Flag Ratio: 2:3
Together with the Danish flag, the Austrian flag is said to be among the oldest national flag designs in the world.
The flag was designed by Duke Leopold V of Austria (1157-1194) while he was involved in a fierce battle during the Crusades. After the Siege of Acre, 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 colours and scheme as his banner.
