Flag of the Serbian Empire

The oldest known drawing of a Serbian flag is from the 1339 map made by Angelino Dulcert; Serbia, at the time ruled by King Stefan Dušan, is represented by a flag of a red double-headed eagle placed above the capital Skopje (Scopi).[7][8] Stefan Dušan was crowned Emperor in 1346; Dušan also adopted the Byzantine tetragramme with four fire-steels, which afterwards became an element of the Serbian flag until today (the Serbian cross).[9] A flag in Hilandar, seen by Dimitrije Avramović, was alleged by the brotherhood to have been a flag of Emperor Dušan; it was a triband of red at the top and bottom and white in the centre.[10] Emperor Dušan also adopted the Imperial divelion, which was purple and had a golden cross in the centre.[11] Another of Dušan's flags was the Imperial cavalry flag, kept at the Hilandar monastery on Mount Athos; a triangular bicolor flag, of red and yellow
