The national flag of Austria is a triband in the following order: red, white, and red. The Austrian flag is considered one of the oldest national symbols still in use by a modern country, with its first recorded use in 1230. The origin of the Bindenschild has not been conclusively established; it possibly derived from the Styrian margraves of the Otakar noble family, who themselves may have adopted the colours from the descendants of the Carinthian duke Adalbero (ruled 1011–1035), a scion of the House of Eppenstein extinct in 1122. These were the family colours of the Imperial House of Habsburg, and were themselves in part derived from the banner of the Holy Roman Empire.
The Austrian flag has been featured or included on multiple collector coins.
