Flag of Flanders
|Design||A yellow field charged with the Flemish coat of arms in the center.|
The flag was officially adopted by the Cultural Council for the Dutch Cultural Community (Cultuurraad voor de Nederlandse Cultuurgemeenschap) in 1973, and later, in 1985, by its successor, the Flemish Parliament. In 1990, also the coat of arms was adopted as an official symbol. 
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.
