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.

John Philip Brooke Brooke-Little, CVO, FSA, FHS, (6 April 1927 –13 February 2006) was an influential and popular writer on heraldic subjects and a long-serving officer of arms at the College of Arms in London, England. In 1947, while still a student, Brooke-Little founded the "Society of Heraldic Antiquaries." This organization is now known as The Heraldry Society and is recognized as one of the leading learned societies in its field. He also served as the society's chairman for 50 years until 1997 and then as its President. ( more...)

The Flag of Scotland, ( Scottish Gaelic: Bratach nàiseanta na h-Alba, Scots: Banner o Scotland), also known as Saint Andrew's Cross or The Saltire, is the national flag of Scotland. Consisting of a blue background over which is placed a white representation of an X-shaped cross, the Saltire is one of Scotland's most recognisable symbols.

According to legend, the Christian apostle and martyr Saint Andrew, the patron saint of Scotland, was crucified on an X-shaped cross at Patras, (Patrae), in Achaea. Use of the familiar iconography of his martyrdom, showing the apostle bound to an X-shaped cross, first appears in the Kingdom of Scotland in 1180 during the reign of William I. Use of a simplified symbol associated with Saint Andrew which does not depict his image has its origins in the late 14th century. The earliest reference to the Saint Andrew's Cross as a flag is to be found in the Vienna Book of Hours, circa 1503, where a white saltire is depicted with a red background. In the case of Scotland, use of a blue background for the Saint Andrew's Cross is said to date from at least the 15th century. ( more...)

The current Coat of arms of the Basque Country is the official coat of arms of the Basque Country, Autonomous community of Spain. It consists of a party per cross representing the three historical territories of Álava, Guipuscoa and Biscay, as well as a fourth, void quarter. The arms are ringed by a regal wreath of oak leaves, symbolic of the Gernikako Arbola. The fourth quarter once constituted the linked chains of Navarre; however, following a legal suit by the Navarre Government claiming that the usage of the arms of a region on the flag of another was illegal, the Constitutional Court of Spain bound to remove the chains of Navarre in a judgment of 1986.
