Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was the monarch of Prussia from 1740 until his death in 1786. He was the last Hohenzollern monarch titled King in Prussia, declaring himself King of Prussia after annexing Royal Prussia from the Polish–Lithuanian Commonwealth in 1772. His most significant accomplishments include military successes in the Silesian wars, reorganisation of the Prussian Army, the First Partition of Poland, and patronage of the arts and the Enlightenment. Prussia greatly increased its territories and became a major military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "Old Fritz" (German: der Alte Fritz).

In his youth, Frederick was more interested in music and philosophy than war, which led to clashes with his authoritarian father, Frederick William I of Prussia. However, upon ascending to the throne, he attacked and annexed the rich Austrian province of Silesia in 1742, winning military acclaim. He became an influential military theorist, whose analyses emerged from his extensive personal battlefield experience and covered issues of strategy, tactics, mobility and logistics.

Cleopatra Selene (Ancient Greek: Κλεοπάτρα Σελήνη; c. between 135 and 130 – 69 BC) was the Queen consort of Egypt (Cleopatra Selene or Cleopatra V Selene) from 115 to 102 BC, the Queen consort of Syria from 102 to 92 BC, and the monarch of Syria (Cleopatra II) from 82 to 69 BC. The daughter of Ptolemy VIII Physcon and Cleopatra III of Egypt, Cleopatra Selene was favoured by her mother and became a pawn in Cleopatra III's political manoeuvres. In 115 BC, Cleopatra III forced her son Ptolemy IX to divorce his sister-wife Cleopatra IV, and chose Cleopatra Selene as the new queen consort of Egypt. Tension between the king and his mother grew and ended with his expulsion from Egypt, leaving Cleopatra Selene behind; she probably then married the new king, her other brother Ptolemy X.

Following the marriage of the Syrian Seleucid princess Cleopatra I to Ptolemy V of Egypt, dynastic marriages between the two kingdoms became common. In 102 BC, Cleopatra III decided to establish an alliance with her nephew Antiochus VIII of Syria; Cleopatra Selene was sent as his bride. After his assassination in 96 BC, she married his brother and rival Antiochus IX. Cleopatra Selene lost her new husband in 95 BC and married a final time to Antiochus IX's son Antiochus X, who disappeared from the records and is presumed to have died in 92 BC, but may have remained in power until 89/88 BC (224 SE (Seleucid year)). Cleopatra Selene then hid somewhere in the kingdom with her children. Eventually, Syria split between the sons of Antiochus VIII with Philip I ruling in the Syrian capital Antioch and Antiochus XII in the southern city Damascus. (Full article...)

Thurisind (Latin: Turisindus, died c. 560) was king of the Gepids, an East Germanic Gothic people, from c. 548 to 560. He was the penultimate Gepid king, and succeeded King Elemund by staging a coup d'état and forcing the king's son into exile. Thurisind's kingdom, known as Gepidia, was located in Central Europe and had its centre in Sirmium, a former Roman city on the Sava River (now the town of Sremska Mitrovica, Serbia).

His reign was marked by multiple wars with the Lombards, a Germanic people who had arrived in the former Roman province of Pannonia under the leadership of their king, Audoin. Thurisind also had to face the hostility of the Byzantine Empire, which was resentful of the Gepid takeover of Sirmium and anxious to diminish Gepid power in the Pannonian Basin, a plain covering most of modern Hungary and partly including the bordering states. The Byzantines' plans to reduce the Gepids' power took effect when Audoin decisively defeated Thurisind in 551 or 552. The Byzantine Emperor Justinian forced a peace accord on both leaders so that equilibrium in the Pannonian Basin could be sustained. (Full article...)

Shepseskare or Shepseskara (Egyptian for "Noble is the Soul of Ra"; died c. 2458 BC) was an Ancient Egyptian king, the fourth or fifth ruler of the Fifth Dynasty (2494–2345 BC) during the Old Kingdom period. Shepseskare lived in the mid-25th century BC and was probably the owner of an unfinished pyramid in Abusir, which was abandoned after a few weeks of work in the earliest stages of its construction.

Following historical sources, Shepseskare was traditionally believed to have reigned for seven years, succeeding Neferirkare Kakai and preceding Neferefre on the throne, making him the fourth ruler of the dynasty. He is the most obscure ruler of this dynasty and the Egyptologist Miroslav Verner has strongly argued that Shepseskare's reign lasted only a few months at the most, after that of Neferefre. This conclusion is based upon the state and location of Shepseskare's unfinished pyramid in Abusir as well as the very small number of artefacts attributable to this king. Verner's arguments have now convinced several Egyptologists such as Darrell Baker and Erik Hornung. (Full article...)

Prince William, Duke of Gloucester (William Henry; 24 July 1689 – 30 July 1700), was the son of Princess Anne (later Queen of England, Ireland and Scotland from 1702) and her husband, Prince George of Denmark. He was their only child to survive infancy. Styled Duke of Gloucester, he was viewed by contemporaries as a Protestant champion because his birth seemed to cement the Protestant succession established in the "Glorious Revolution" that had deposed his Catholic grandfather James II & VII the previous year.

Anne was estranged from her brother-in-law and cousin, William III & II, and her sister, Mary II, but supported links between them and her son. He grew close to his uncle William, who created him a Knight of the Garter, and his aunt Mary, who frequently sent him presents. At his nursery in Campden House, Kensington, he befriended his Welsh body-servant, Jenkin Lewis, whose memoir of the Duke is an important source for historians, and operated his own miniature army, called the "Horse Guards", which eventually comprised 90 boys.

Atlanersa (also Atlanarsa) was a Kushite ruler of the Napatan kingdom of Nubia, reigning for about a decade in the mid-7th century BC. He was the successor of Tantamani, the last ruler of the 25th Dynasty of Egypt, and possibly a son of Taharqa or less likely of Tantamani, while his mother was a queen whose name is only partially preserved. Atlanersa's reign immediately followed the collapse of Nubian control over Egypt, which witnessed the Assyrian conquest of Egypt and then the beginning of the Late Period under Psamtik I. The same period also saw the progressive cultural integration of Egyptian beliefs by the Kushite civilization.

Atlanersa may have fathered his successor Senkamanisken with his consort Malotaral, although Senkamanisken could also be his brother. He built a pyramid in the necropolis of Nuri, now conjecturally believed to be Nuri 20 and may also have started a funerary chapel in the same necropolis, now called Nuri 500. Atlanersa was the second Nubian king to build a pyramid in Nuri after Taharqa. Excavations of his pyramid produced many small artefacts which are now on display in the Museum of Fine Arts in Boston, US. Atlanersa's most-prominent construction is his temple to the syncretic god Osiris-Dedwen in Jebel Barkal called B700, which he finished and had time to only partially decorate. This suggests that he died unexpectedly. The temple entrance was to be flanked with two colossal statues of the king, one of which was completed and set in place and is now in the National Museum of Sudan. (Full article...)

George III (George William Frederick; 4 June 1738 – 29 January 1820) was King of Great Britain and Ireland from 25 October 1760 until his death in 1820. The Acts of Union 1800 unified Great Britain and Ireland into the United Kingdom of Great Britain and Ireland, with George as its king. He was concurrently Duke and Prince-elector of Hanover in the Holy Roman Empire before becoming King of Hanover on 12 October 1814. He was a monarch of the House of Hanover, who, unlike his two predecessors, was born in Great Britain, spoke English as his first language, and never visited Hanover.

George was born during the reign of his paternal grandfather, King George II, as the first son of Frederick, Prince of Wales, and Princess Augusta of Saxe-Gotha. Following his father's death in 1751, Prince George became heir apparent and Prince of Wales. He succeeded to the throne on George II's death in 1760. The following year, he married Princess Charlotte of Mecklenburg-Strelitz, with whom he had 15 children. George III's life and reign were marked by a series of military conflicts involving his kingdoms, much of the rest of Europe, and places farther afield in Africa, the Americas and Asia. Early in his reign, Great Britain defeated France in the Seven Years' War, becoming the dominant European power in North America and India. However, Britain lost 13 of its North American colonies in the American War of Independence. Further wars against revolutionary and Napoleonic France from 1793 concluded in the defeat of Napoleon at the Battle of Waterloo in 1815. In 1807, the transatlantic slave trade was banned from the British Empire. (Full article...)

Abū al-ʿAbbās Aḥmad ibn Ṭalḥa ibn Jaʿfar ibn Muḥammad ibn Hārūn (Arabic: أبو العباس أحمد بن طلحة الموفق), 853/4 or 860/1 – 5 April 902, better known by his regnal name al-Muʿtaḍid bi-llāh (Arabic: المعتضد بالله, lit. 'Seeking Support in God'), was the caliph of the Abbasid Caliphate from 892 until his death in 902.

Al-Mu'tadid was the son of al-Muwaffaq, who was the regent and effective ruler of the Abbasid state during the reign of his brother, Caliph al-Mu'tamid. As a prince, the future al-Mu'tadid served under his father during various military campaigns, most notably in the suppression of the Zanj Rebellion, in which he played a major role. When al-Muwaffaq died in June 891 al-Mu'tadid succeeded him as regent. He quickly sidelined his cousin and heir-apparent al-Mufawwid; when al-Mu'tamid died in October 892, he succeeded to the throne. Like his father, al-Mu'tadid's power depended on his close relations with the army. These were first forged during the campaigns against the Zanj and were reinforced in later expeditions which the Caliph led in person: al-Mu'tadid would prove to be the most militarily active of all Abbasid caliphs. Through his energy and ability, he succeeded in restoring to the Abbasid state some of the power and provinces it had lost during the turmoil of the previous decades. (Full article...)

Coenred (also spelled Cenred or Cœnred fl. 675–709) was king of Mercia from 704 to 709. Mercia was an Anglo-Saxon kingdom in the English Midlands. He was a son of the Mercian king Wulfhere, whose brother Æthelred succeeded to the throne in 675 on Wulfhere's death. In 704, Æthelred abdicated in favour of Coenred to become a monk.

Coenred's reign is poorly documented, but a contemporary source records that he faced attacks from the Welsh. Coenred is not known to have married or had children, although later chronicles describe him as an ancestor of Wigstan, a 9th-century Mercian king. In 709, Coenred abdicated and went on pilgrimage to Rome, where he remained as a monk until his death. In the view of his contemporary, Bede, Coenred "who had ruled the kingdom of Mercia for some time and very nobly, with still greater nobility renounced the throne of his kingdom". Æthelred's son Ceolred succeeded Coenred as king of Mercia. (Full article...)

Tiberius III (Greek: Τιβέριος, romanized: Tibérios), born Apsimar (Latin: Apsimarus; Greek: Ἀψίμαρος, romanized: Apsímaros), was Byzantine emperor from 698 to 705. Little is known about his early life, other than that he was a droungarios, a mid-level commander, who served in the Cibyrrhaeot Theme. In 696, Tiberius was part of an army sent by Byzantine Emperor Leontius to retake the North African city of Carthage, which had been captured by the Arab Umayyads. After seizing the city, this army was pushed back by Umayyad reinforcements and retreated to the island of Crete. As they feared the wrath of Leontius, some officers killed their commander, John the Patrician, and declared Tiberius the emperor. Tiberius swiftly gathered a fleet and sailed for Constantinople, where he then deposed Leontius. Tiberius did not attempt to retake Byzantine Africa from the Umayyads, but campaigned against them along the eastern border with some success. In 705, former emperor Justinian II, who had been deposed by Leontius, led an army of Slavs and Bulgars from the First Bulgarian Empire to Constantinople, and after entering the city secretly, deposed Tiberius. Tiberius fled to Bithynia, but was captured a few months later and beheaded by Justinian between August 705 and February 706. His body was initially thrown into the sea, but was later recovered and buried in a church on the island of Prote. (Full article...)

Abū Bakr Muḥammad ibn Ṭughj ibn Juff ibn Yiltakīn ibn Fūrān ibn Fūrī ibn Khāqān (8 February 882 – 24 July 946), better known by the title al-Ikhshīd (Arabic: الإخشيد) after 939, was an Abbasid commander and governor who became the autonomous ruler of Egypt and parts of Syria (Levant) from 935 until his death in 946. He was the founder of the Ikhshidid dynasty, which ruled the region until the Fatimid conquest of 969.

The son of Tughj ibn Juff, a general of Turkic origin who served both the Abbasids and the autonomous Tulunid rulers of Egypt and Syria, Muhammad ibn Tughj was born in Baghdad but grew up in Syria and acquired his first military and administrative experiences at his father's side. He had a turbulent early career: he was imprisoned along with his father by the Abbasids in 905, was released in 906, participated in the murder of the vizier al-Abbas ibn al-Hasan al-Jarjara'i in 908, and fled Iraq to enter the service of the governor of Egypt, Takin al-Khazari. Eventually he acquired the patronage of several influential Abbasid magnates, chiefly the powerful commander-in-chief Mu'nis al-Muzaffar. These ties led him to being named governor first of Palestine and then of Damascus. In 933, he was briefly named governor of Egypt, but this order was revoked after the death of Mu'nis, and Ibn Tughj had to fight to preserve even his governorship of Damascus. In 935, he was re-appointed to Egypt, where he quickly defeated a Fatimid invasion and stabilized the turbulent country. His reign marks a rare period of domestic peace, stability and good government in the annals of early Islamic Egypt. In 938 Caliph al-Radi granted his request for the title of al-Ikhshid, which had been borne by the rulers of his ancestral Farghana Valley. It is by this title that he was known thereafter.

Edmund I or Eadmund I (920/921 – 26 May 946) was King of the English from 27 October 939 until his death in 946. He was the elder son of King Edward the Elder and his third wife, Queen Eadgifu, and a grandson of King Alfred the Great. After Edward died in 924, he was succeeded by his eldest son, Edmund's half-brother Æthelstan. Edmund was crowned after Æthelstan died childless in 939. He had two sons, Eadwig and Edgar, by his first wife Ælfgifu, and none by his second wife Æthelflæd. His sons were young children when he was killed in a brawl with an outlaw at Pucklechurch in Gloucestershire, and he was succeeded by his younger brother Eadred, who died in 955 and was followed by Edmund's sons in succession.

Æthelstan had succeeded as the king of England south of the Humber and he became the first king of all England when he conquered Viking-ruled York in 927, but after his death Anlaf Guthfrithson was accepted as King of York and extended Viking rule to the Five Boroughs of north-east Mercia. Edmund was initially forced to accept the reverse, the first major setback for the West Saxon dynasty since Alfred's reign, but he was able to recover his position following Anlaf's death in 941. In 942, Edmund took back control of the Five Boroughs and in 944 he regained control over the whole of England when he expelled the Viking kings of York. Eadred had to deal with further revolts when he became king, and York was not finally conquered until 954. Æthelstan had achieved a dominant position over other British kings and Edmund maintained this, perhaps apart from Scotland. The north Welsh king Idwal Foel may have allied with the Vikings as he was killed by the English in 942. The British kingdom of Strathclyde may also have sided with the Vikings as Edmund ravaged it in 945 and then ceded it to Malcolm I of Scotland. Edmund also continued his brother's friendly relations with Continental rulers, several of whom were married to his half-sisters. (Full article...)

Manuel Marques de Sousa, Count of Porto Alegre (13 June 1804 – 18 July 1875), nicknamed "the Gloved Centaur", was an army officer, politician and abolitionist of the Empire of Brazil. Born into a wealthy family of military background, Manuel Marques de Sousa joined the Portuguese Army in Brazil in 1817 when he was little more than a child. His military initiation occurred in the conquest of the Banda Oriental (Eastern Bank), which was annexed and became the southernmost Brazilian province of Cisplatina in 1821. For most of the 1820s, he was embroiled in the Brazilian effort to keep Cisplatina as part of its territory: first during the struggle for Brazilian independence and then in the Cisplatine War. It would ultimately prove a futile attempt, as Cisplatina successfully separated from Brazil to become the independent nation of Uruguay in 1828.

A few years later, in 1835 his native province of Rio Grande do Sul was engulfed in a secessionist rebellion, the Ragamuffin War. The conflict lasted for almost ten years, and the Count was leading military engagements for most of that time. He played a decisive role in saving the provincial capital from the Ragamuffin rebels, allowing forces loyal to the legitimate government to secure a key foothold. In 1852, he led a Brazilian division during the Platine War in an invasion of the Argentine Confederation that overthrew its dictator. He was awarded a noble title, eventually raised from baron to viscount and finally to count. (Full article...)

Martinus (Ancient Greek: Μαρτίνος, romanized: Martínos) or Marinus (Greek: Μαρίνος, romanized: Marínos; died possibly in 641) was caesar of the Byzantine Empire from c. 639 to 641. Martinus was the fifth son of Emperor Heraclius and Empress Martina, who was Heraclius' second wife and niece. Martinus was elevated to caesar, a junior imperial title that placed him on the line of succession, at some point between 638 and 640 by his father.

Heraclius died on 11 February 641, leaving the Byzantine Empire to Martinus's half-brother Constantine III and his elder full brother Heraclonas; Constantine III soon died of tuberculosis, although some of his partisans alleged that Martina poisoned him. One such partisan, Valentinus, led troops to Chalcedon, across the Bosporus strait from the imperial capital, Constantinople, to force Martina to install Constans II, the son of Constantine III, as co-emperor. Valentinus seized Constantinople and forced Martina to install Constans II in September or October 641, and deposed Martina, Heraclonas, and Martinus. Martinus was mutilated and exiled to Rhodes. He died soon after, possibly during or immediately after the mutilations. (Full article...)

Tolui (c. 1191–1232) was the youngest son of Genghis Khan and Börte. A prominent general during the early Mongol conquests, Tolui was a leading candidate to succeed his father after his death in 1227 and ultimately served as regent of the Mongol Empire until the accession of his brother Ögedei two years later. Tolui's wife was Sorghaghtani Beki; their sons included Möngke and Kublai, the fourth and fifth khans of the empire, and Hulagu, the founder of the Ilkhanate.

Tolui was less active than his elder brothers Jochi, Chagatai, and Ögedei during their father's rise to power, but once he reached adulthood he was considered the finest warrior of the four. He commanded armies under his father during the first invasion of Jin China (1211–1215), and his distinguished service during the Mongol invasion of the Khwarazmian Empire secured his reputation. After the fall of the cities of Transoxiana in 1220, Genghis dispatched Tolui early the following year to subjugate the region of Khorasan, which had begun to cause trouble for the Mongol armies. Tolui executed his orders with ruthless efficiency, assaulting the major cities of Merv, Nishapur, and Herat, and subjugating numerous others. Medieval chroniclers attributed more than three million deaths to the massacres he ordered at Nishapur and Merv; while these figures are considered exaggerated by modern historians, they are evidence of the abnormal brutality of Tolui's campaign.

Constantine Angelos (Greek: Κωνσταντῖνος Ἄγγελος; c. 1093 – after 1166) was a Byzantine aristocrat who married into the Komnenian dynasty and served as a military commander under Manuel I Komnenos, serving in the western and northern Balkans and as an admiral against the Normans. He was the founder of the Angelos dynasty, which went on to rule the Byzantine Empire in 1185–1204 and found and rule the Despotate of Epirus (1205–1318) and the Empire of Thessalonica (1224–1242/46).

King of Sumer and Akkad (Sumerian: 𒈗𒆠𒂗𒄀𒆠𒌵 lugal-ki-en-gi-ki-uri, Akkadian: šar māt Šumeri u Akkadi) was a royal title in Ancient Mesopotamia combining the titles of "King of Akkad", the ruling title held by the monarchs of the Akkadian Empire (2334–2154 BC) with the title of "King of Sumer". The title simultaneously laid a claim on the legacy and glory of the ancient empire that had been founded by Sargon of Akkad (r. 2334–2279 BC) and expressed a claim to rule the entirety of lower Mesopotamia (composed of the regions of Sumer in the south and Akkad in the north). Despite both of the titles "King of Sumer" and "King of Akkad" having been used by the Akkadian kings, the title was not introduced in its combined form until the reign of the Neo-Sumerian king Ur-Nammu (c. 2112–2095 BC), who created it in an effort to unify the southern and northern parts of lower Mesopotamia under his rule. The older Akkadian kings themselves might have been against linking Sumer and Akkad in such a way.

In later centuries of Mesopotamian history, when the major kingdoms were Assyria and Babylon, the title was mostly used by monarchs of Babylon since they ruled lower Mesopotamia. For Assyrian kings, the title became a formal assertion of authority over the city of Babylon and its surroundings; only those Assyrian rulers who actually controlled Babylon used the title and when Assyria permanently lost control of Babylon to the Neo-Babylonian Empire, the rulers of that empire began using it instead. The final king to claim to be the King of Sumer and Akkad was Cyrus the Great (r. c. 559–530 BC) of the Achaemenid Empire, who assumed several traditional Mesopotamian titles after his conquest of Babylon in 539 BC.

Juneyd or Junayd Bey (Turkish: İzmiroğlu Cüneyd; fl. before 1402 – 1425) was the last ruler (bey) of the Aydınid principality in what is now central western Turkey. His exact relationship with the Aydınid dynasty is unclear. His father was a long-time and popular governor of Smyrna under the Ottoman sultan Bayezid I. This allowed Junayd to consistently rely on the loyalty of the area's populace.

Bayezid was defeated by Timur at the Battle of Ankara, beginning a civil war for succession between his sons – a period known as the "Ottoman Interregnum". Taking advantage of the situation, Junayd attacked the Aydınid brothers, Isa and Umur II, who had been restored by Timur. By early 1406, Isa and Umur were dead and Junayd was the undisputed ruler of the former Aydınid domains. Like all the rulers of the region, Christian and Muslim alike, Junayd was also an active participant in the civil war between Bayezid's sons İsa, Süleyman, Musa and Mehmed, in which he changed his allegiance several times. He supported İsa against Mehmed, and became a vassal of Süleyman. His persistent attempts to exploit the conflict to broaden his power and independence forced Süleyman to send him as provincial governor of Ohrid in Rumeli in 1410. After Süleyman's overthrow and death in 1411 at the hands of his brother Musa, Junayd returned to Anatolia and seized Smyrna, but had to recognize the suzerainty of Mehmed. During Mehmed's absence in Rumeli to campaign against Musa, Junayd reclaimed his independence and attacked his neighbouring rulers. As a result, in 1414 Mehmed led a regional coalition against Junayd. Junayd's mother was able to save his life, but once again Junayd was dispossessed and sent to Rumeli as governor of Nicopolis. From there, he joined the unsuccessful rebellion of Mustafa Çelebi, until the Byzantines agreed to intern him and Mustafa in 1416. (Full article...)

Mary Woffington Cholmondeley (1729 – 4 April 1811) was an Irish socialite of the Georgian era. Her sister was the famous actor Peg Woffington. After a failed attempt at an acting career, Mary married the second son of the Earl of Cholmondeley and chose to live as a socialite. With connections in both English and French high society, she came to have a "modest salon", and was close friends with Frances Burney and Samuel Johnson. (Full article...)

Burebista (Ancient Greek: Βυρεβίστας, Βοιρεβίστας) was the king of the Getae and Dacian tribes from 82/61 BC to 45/44 BC. He was the first king who successfully unified the tribes of the Dacian kingdom, which comprised the area located between the Danube, Tisza, and Dniester rivers, and modern day Romania and Moldova. In the 7th and 6th centuries BC it became home to the Thracian peoples, including the Getae and the Dacians. From the 4th century to the middle of the 2nd century BC the Dacian peoples were influenced by La Tène Celts who brought new technologies with them into Dacia. Sometime in the 2nd century BC, the Dacians expelled the Celts from their lands. Dacians often warred with neighbouring tribes, but the relative isolation of the Dacian peoples in the Carpathian Mountains allowed them to survive and even to thrive. By the 1st century BC the Dacians had become the dominant power.

From 61 BC onwards Burebista pursued a series of conquests that expanded the Dacian kingdom. The tribes of the Boii and Taurisci were destroyed early in his campaigns, followed by the conquest of the Bastarnae and probably the Scordisci peoples. He led raids throughout Thrace, Macedonia, and Illyria. From 55 BC the Greek cities on the west coast of the Black Sea were conquered one after another. These campaigns inevitably culminated in conflict with Rome in 48 BC, at which point Burebista gave his support to Pompey. This in turn made him an enemy to Julius Caesar, who decided to start a campaign against Dacia. This plan fell through in 44 BC when Caesar was assassinated. Burebista himself was assassinated in a plot by the Dacian aristocracy at around the same time. (Full article...)

Gaius Pius Esuvius Tetricus was a Gallo-Roman nobleman who ruled as emperor of the Gallic Empire from 271 to 274 AD. He was originally the praeses (provincial governor) of Gallia Aquitania and became emperor after the murder of Emperor Victorinus in 271, with the support of Victorinus's mother, Victoria. During his reign, he faced external pressure from Germanic raiders, who pillaged the eastern and northern parts of his empire, and the Roman Empire, from which the Gallic Empire had seceded. He also faced increasing internal pressure, which led him to declare his son, Tetricus II, caesar in 273 and possibly co-emperor in 274, although this is debated. The Roman emperor Aurelian invaded in 273 or 274, leading to the Battle of Châlons, at which Tetricus surrendered. Whether this capitulation was the result of a secret agreement between Tetricus and Aurelian or that surrender was necessary after his defeat is debated. Aurelian spared Tetricus, and made him a senator and the corrector (governor) of Lucania et Bruttium. Tetricus died of natural causes a few years after 274. (Full article...)

Stanisław Poniatowski (15 September 1676 – 29 August 1762) was a Polish military commander, diplomat, and noble. Throughout his career, Poniatowski served in various military offices, and was a general in both the Swedish and Polish–Lithuanian militaries. He also held numerous civil positions, including those of podstoli of Lithuania and Grand Treasurer of the Lithuanian army in 1722, voivode of the Masovian Voivodeship in 1731, regimentarz of the Crown Army in 1728, and castellan of Kraków in 1752. Throughout his lifetime, he served in many starost positions.

Poniatowski was involved in Commonwealth politics, and was a prominent member of the Familia, a faction led by the Czartoryski family. On a number of occasions he was in service of Stanisław I Leszczyński, the principal rival of Augustus II for the throne of Poland. Having served under Leszczyński as a military officer and envoy during the Great Northern War, Poniatowski later embraced the Russian-supported Augustus. Subsequently, during the War of the Polish Succession, he returned, with the majority of the Familia, to his earlier allegiance. He later effected a reconciliation with Augustus III, and eventually became one of the new king's chief advisors. (Full article...)

Boïsesthlabos (Greek: Βοϊσέσθλαβος), transliterated as Višeslav (Serbian Cyrillic: Вишеслав) or Vojislav (Serbian Cyrillic: Војислав), is the first Serbian ruler known by name, who ruled in c. 780. Serbia was a Slavic principality, subject to the Byzantine Empire, located in the western Balkans, bordering with Bulgaria in the east. Mentioned in the De Administrando Imperio (DAI) from the mid-10th century, Višeslav was a progenitor of the Serbian ruling family, known in historiography as the Vlastimirović dynasty. He was descended from the unnamed "Serbian prince" who led his people to the Dalmatia province and established hereditary rule under Byzantine suzerainty. The names of Višeslav's predecessors were not included in the DAI. The dynasty ruled the Principality of Serbia from the early 8th century until around 960. (Full article...)

Marcus Annius Florianus (died 276), also known as Florian, was Roman emperor from the death of his half-brother, Emperor Tacitus, in July 276 until his own murder in September of that year.

Florianus was the maternal half-brother of Tacitus, who was proclaimed emperor in late 275 after the unexpected death of Emperor Aurelian. After Tacitus died the following year, allegedly assassinated as a consequence of a military plot, Florianus proclaimed himself emperor, with the recognition of the Roman Senate and much of the empire. However, the new emperor soon had to deal with the revolt of Probus, who rose up shortly after Florianus ascended the throne, with the backing of the provinces of Egypt, Syria, Palestine, and Phoenicia. Probus took advantage of the terrain of the Cilician Gates, and the hot climate of the area, to which Florianus' army was unaccustomed, to chip away at their morale. Florianus' army rose up against him and killed him. (Full article...)

Hugh of Fauquembergues, also known as Hugh of St Omer, Hugh of Falkenberg, or Hugh of Falchenberg (Latin: Hugo de Falchenberch; died in 1105 or 1106) was Prince of Galilee from 1101 to his death. He was Lord of Fauquembergues before joining the First Crusade. Baldwin I of Jerusalem granted him Galilee after its first prince, Tancred, who was Baldwin's opponent, had voluntarily renounced it. Hugh assisted Baldwin against the Fatimids and made raids into Seljuk territories. He established the castles of Toron and Chastel Neuf (at present-day Tebnine and Hunin, respectively). He died fighting against Toghtekin, Atabeg of Damascus. (Full article...)

Anastasius I Dicorus (Ancient Greek: Ἀναστάσιος, romanized: Anastásios; c. 431 – 9 July 518) was Roman emperor from 491 to 518. A career civil servant, he came to the throne at the age of 61 after being chosen by Ariadne, the wife of his predecessor, Zeno. His reign was characterized by reforms and improvements in the empire's government, finances, economy and bureaucracy. The resulting stable government, reinvigorated monetary economy and sizeable budget surplus allowed the empire to pursue more ambitious policies under his successors, most notably Justinian I. Since many of Anastasius' reforms proved long-lasting, his influence over the empire endured for centuries.

Anastasius was a Miaphysite Christian and his personal religious tendencies caused tensions throughout his reign in the empire that was becoming increasingly divided along religious lines. (Full article...)

The reign of Marcus Aurelius began with his accession on 7 March 161 following the death of his adoptive father, Antoninus Pius, and ended with his own death on 17 March 180. Marcus first ruled jointly with his adoptive brother, Lucius Verus. They shared the throne until Lucius' death in 169. Marcus was succeeded by his son Commodus, who had been made co-emperor in 177.

Under Marcus, Rome fought the Roman–Parthian War of 161–66 and the Marcomannic Wars. The so-called Antonine plague occurred during his reign. In the last years of his rule, Marcus composed his personal writings on Stoic philosophy known as Meditations. (Full article...)

Andrianampoinimerina (Malagasy pronunciation: [anˈɖʐianˌmpuʲnˈmerʲnə̥]) (c. 1745–1810) ruled the Kingdom of Imerina on Madagascar from 1787 until his death. His reign was marked by the reunification of Imerina following 77 years of civil war, and the subsequent expansion of his kingdom into neighboring territories, thereby initiating the unification of Madagascar under Merina rule. Andrianampoinimerina is a cultural hero and holds near mythic status among the Merina people, and is considered one of the greatest military and political leaders in the history of Madagascar.

Andrianampoinimerina took power upon deposing his uncle, King Andrianjafy, who had ruled over Imerina Avaradrano (Northern Imerina). Prior to Andrianampoinimerina's reign, Imerina Avaradrano had been locked in conflict with the three other neighboring provinces of the former kingdom of Imerina that had last been unified under King Andriamasinavalona a century before. Andrianampoinimerina established his capital at the fortified town of Ambohimanga, a site of great spiritual, cultural and political significance that was designated a UNESCO World Heritage Site in 2001. The king's original royal lodgings can still be visited at Ambohimanga today. From this position, he progressively extended his domain first over all Imerina and then over the greater Highlands, absorbing the Betsileo, Sihanaka, Bezanozano and Bara territories. Having reigned for 23 years at the time of his death, Andrianampoinimerina had successfully reunited Imerina and vastly expanded the Merina kingdom, with the intent to ultimately unify all of Madagascar under Merina rule. His son and heir, Radama I, continued the conquests Andrianampoinimerina had begun, and over the next two decades largely achieved his father's vision. (Full article...)

Alexios V Doukas (Greek: Ἀλέξιος Δούκας; died December 1204), Latinized as Alexius V Ducas, was Byzantine emperor from February to April 1204, just prior to the sack of Constantinople by the participants of the Fourth Crusade. His family name was Doukas, but he was also known by the nickname Mourtzouphlos or Murtzuphlus (Μούρτζουφλος), referring to either bushy, overhanging eyebrows or a sullen, gloomy character. He achieved power through a palace coup, killing his predecessors in the process. Though he made vigorous attempts to defend Constantinople from the crusader army, his military efforts proved ineffective. His actions won the support of the mass of the populace, but he alienated the elite of the city. Following the fall, sack, and occupation of the city, Alexios V was blinded by his father-in-law, the ex-emperor Alexios III, and later executed by the new Latin regime. He was the last Byzantine emperor to rule in Constantinople until the Byzantine recapture of Constantinople in 1261. (Full article...)

Andronikos Doukas (Greek: Ἀνδρόνικος Δούκας, c. 1057 – c. 1077 or after 1081), Latinized as Andronicus Ducas, was the third son of Byzantine emperor Constantine X Doukas (r. 1059–1067) and younger brother of Byzantine emperor Michael VII Doukas (r. 1071–1078). Unlike his other brothers, he was not named junior co-emperor by his father, and was raised to the dignity only by Romanos IV Diogenes (r. 1068–1071). He is otherwise relatively insignificant, and was not involved in the affairs of state to any degree. (Full article...)
