The flag of Austria has three equal horizontal bands of red (top), white, and red. Together with the Danish flag, the Austrian flag is said to be among the oldest national flag designs in the world.
Duke Friedrich II (1210-1246), the last Babenberg, known as the Quarrelsome or the Warlike, to become more independent from the Holy Roman Empire designed a new coat of arm red-white-red in the year 1230.
Legend
According to legend, the flag was invented by Duke Leopold V of Austria while he was involved in a fierce battle during the Crusades. After the battle, his white battledress was completely drenched in blood, but when he removed his belt the cloth underneath was untouched by it. So taken was he by this singular sight that he adopted the colors and scheme as his banner.
