The national flag of Austria (Flagge Österreichs) 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 Austrian triband originated from the arms of the Babenberg dynasty. As opposed to other flags, such as the black-and-yellow banner of the Habsburgs, the red-white-red flag was from very early on associated, not with a reigning family or monarch, but with the country itself.
In addition to serving as the flag of Austria since 1230, it was adopted as the naval ensigns and state flags of the Kingdom of Lombardy–Venetia, Grand Duchy of Tuscany and Duchy of Modena and Reggio in the 18th and 19th centuries respectively, as they were ruled by the House of Habsburg or its cadet branches.
