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.

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.

Canadian heraldry refers to the cultural tradition and style of coats of arms and other heraldic achievements in modern and historic Canada, including national, provincial, and civic arms, noble and personal arms, ecclesiastical heraldry, heraldic displays as corporate logos, and Canadian heraldic descriptions.

Canadian heraldry derives mainly from heraldic traditions in France and the United Kingdom while adding distinctly Canadian symbols, especially those which reference the First Nations and other aboriginal peoples of Canada. Canadian heraldry has a unique system of cadency for daughters inheriting arms, and a special symbol for United Empire Loyalists. Since 1988, both personal and corporate heraldry in Canada is officially governed by the Canadian Heraldic Authority, which reviews all applications for arms. (more...)

Polish national law defines flags either through an act of parliament or a ministerial ordinance. Apart from the national flag, these are mostly military flags, used by one or all branches of the Polish Armed Forces, especially the Polish Navy. Flags flown by vessels of non-military uniformed services are also included in the list.

Most of the flags feature white and red, the national colors of Poland. The national colors, officially adopted in 1831, are of heraldic origin and derive from the tinctures (colors) of the coats of arms of Poland (the White Eagle) and Lithuania (the Pursuer). Additionally, some flags incorporate the White Eagle itself, either identical with that of the national coat of arms or one of its variants, known as military eagles, used by the Armed Forces.

Sir John Bernard Burke (January 5, 1814 - December 12, 1892) was a British officer of arms and genealogist. He was born in London, and was educated in London and in France. His father, John Burke (1787-1848), was also a genealogist, and in 1826 issued a Genealogical and Heraldic Dictionary of the Peerage and Baronetage of the United Kingdom. This work, generally known as Burke's Peerage, has been issued annually starting in 1847. While practising as a barrister Bernard Burke assisted his father in his genealogical work, and in 1848 took control of his publications. (more...)
