Coat of arms of Flanders

The Arms of the Flemish Community are: Or, a lion rampant sable, armed and langued gules. Although the lion has been in use for almost nine hundred years as the arms of the Count of Flanders, it only became the official symbol of the Flemish Community in 1973. At present its form and use is subject to the Decree of 7 November 1990.

The Flemish lion derives from the arms of the Counts of Flanders. Their first appearance is on a seal of Count Philip of Alsace, dating from 1163. As such they constitute the oldest of the many territorial arms bearing a lion in the Low Countries. Still, Count Philip was not the first of his line to bear a lion, for his cousin, William of Ypres, already used a seal with a lion passant in 1158; and the shield on the enamel effigy of about 1155 from the tomb of his maternal uncle, Geoffrey Plantagenet, Count of Anjou, bears numerous lions rampant.

When the county of Flanders was inherited by the Dukes of Burgundy in 1405, the Flemish lion was placed on an escutcheon in their dynastic arms. It passed with the rest of the Burgundian inheritance to the House of Habsburg in 1482. The Habsburgs would bear the title and arms of the county of Flanders until 1795. As part of the claims and counterclaims resulting from War of the Spanish Succession, the Flemish lion likewise featured in the arms of Kings of Spain until 1931 and in the arms of the kingdom of the Two Sicilies until 1860.

In 1816 the Flemish lion became part of the coats of arms of the provinces of East Flanders and West Flanders that administer most of the territory of the former county.

It is the inverse of the arms of Brabant, which are a gold lion on a black field.

Like many other nationalist movements, the Flemish movement sought and appropriated historical symbols as an instrument for rallying support. The choice of the Flemish lion was primarily based on the popular historical novel De leeuw van Vlaanderen (1838) of Hendrik Conscience, that forged the Battle of the Golden Spurs of 11 July 1302 into an icon of Flemish resistance against foreign oppression. It was enhanced even further when Hippoliet van Peene wrote the anthem De Vlaamse Leeuw in 1847. By the late nineteenth century it was customary for supporters of the Flemish movement to fly the Flemish lion on 11 July.
