Adopted in 1370; The flag of Denmark is red with a white cross that extends to the edges of the flag. The vertical part of the cross is shifted to the hoist side. The banner is referred to as the Dannebrog (Danish flag) and is one of the oldest national flags in the world. Traditions as to the origin of the flag design vary, but the best known is a legend that the banner fell from the sky during an early-13th century battle. Caught up by the Danish king before it ever touched the earth, this heavenly talisman inspired the royal army to victory. In actuality, the flag may derive from a crusade banner or ensign.
