The flag of Austria has three equal horizontal bands of red (top), white, and red. The Austrian flag is possibly the oldest national flag design in the world. The Danish flag and the Austrian flag are said to be the oldest in use.
According to legend, the flag was invented by Duke Leopold V of Austria (1157-1194) as a consequence of his fighting during the Crusades. After a fierce battle, his white battle dress was completely drenched in blood. When he removed his belt, the cloth underneath was untouched by it, revealing the combination of red-white-red. So taken was he by this singular sight that he adopted the colours and scheme as his banner.
