Heraldry encompasses all of the duties of a herald, including the science and art of designing, displaying, describing and recording coats of arms and badges, as well as the formal ceremonies and laws that regulate the use and inheritance of arms. The origins of heraldry lie in the medieval need to distinguish participants in battles or jousts, whose faces were hidden by steel helmets.

Vexillology (from the Latin vexillum, a flag or banner) is the scholarly study of flags, including the creation and development of a body of knowledge about flags of all types, their forms and functions, and of scientific theories and principles based on that knowledge. Flags were originally used to assist military coordination on the battlefield, and have evolved into a general tool for signalling and identification, particularly identification of countries.

Swedish heraldry refers to the cultural tradition and style of heraldic achievements in modern and historic Sweden. It belongs culturally to the German-Nordic heraldic tradition, noted for its multiple helmets and crests which are treated as inseparable from the shield, repetition of colours and charges between the shield and the crest, and its scant use of heraldic furs. Swedish heraldry is similar to Danish heraldry; both were heavily influenced by German heraldry. The medieval history of the Nordic countries was closely related, so they developed their heraldic individuality rather late. Swedish and Finnish heraldry have a shared history prior to the Diet of Porvoo in 1809. Unlike the macaronic and highly stylized English blazon, Swedish heraldry is described in plain language, using only Swedish terminology.

In Sweden today, the official coats of arms of corporations and government offices are protected by Swedish law, if the coat of arms is registered with the Swedish Patent and Registration Office. Heraldic arms of common citizens (burgher arms), however, are less strictly controlled; these are recognised by inclusion in the annually published Scandinavian Roll of Arms. (more...)

William Camden (May 2, 1551–November 9, 1623) was an English antiquarian and historian. He wrote Britannia, the first topographical survey of the island of Great Britain, and Annales, the first detailed historical account of the reign of Elizabeth I of England. In 1597 he was appointed Clarenceux King of Arms to facilitate his research, the post carrying a salary, and the College of Arms at the time being a centre of antiquarian studies. The appointment, however, roused the jealousy of the herald Ralph Brooke, who in retaliation published an attack on Britannia, charging Camden with inaccuracy and plagiarism. Camden successfully defended himself against the charges in subsequent editions of the work. (more...)

The term flag of convenience describes the business practice of registering a merchant ship in a sovereign state different from that of the ship's owners. The term refers to the civil ensign the ship flies to indicate its country of registration or flag state. A ship operates under the laws of its flag state, and these laws are used if the ship is involved in an admiralty case. The modern practice of flagging ships in foreign countries began in the 1920s in the United States, when shipowners frustrated by increased regulations and rising labor costs began to register their ships to Panama. As of 2009, more than half of the world’s merchant ships are registered under flags of convenience. (more...)
