[[File:Flag of the Habsburg Monarchy.svg|thumb|{{FIAV|historical}} Flag of the [[Austrian Empire]] (used {{circa|1804}}–1867)]]
Since the days of [[Rudolph I of Germany|Rudolph of Habsburg]] and the 1283 [[Treaty of Rheinfelden]], the combination of red-white-red was widely considered to be the [[Archduchy of Austria|Austrian]] (later also [[Inner Austria]]n) colours used by the ruling Habsburg dynasty. However, the black-yellow flag was used as the ''national flag'' (in a modern sense) of the Austrian [[Habsburg monarchy]], the later [[Austrian Empire]] and the [[Cisleithania|Austrian]] part of [[Austria-Hungary]], and sometimes even for the entire empire until 1918. 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]].<ref>{{cite web |url=http://www.flaggenlexikon.de/foest3.htm |title=National Flaggen des Österreich-Ungarn |access-date=2004-11-03 |author=Volker Preuß|language=de}}</ref>

Beginning in the reign of Emperor [[Joseph II, Holy Roman Emperor|Joseph II]], the [[Austro-Hungarian Navy|Austrian, later Austro-Hungarian Navy]] used a [[Austro-Hungarian Navy#Naval flags|naval ensign]] (''Marineflagge'') based on the red-white-red colours, and augmented with a shield of similar colours. Both of these flags became obsolete with Austria-Hungary's dissolution in 1918, and the newly formed rump state of [[German Austria]] adopted the red-white-red triband as its national flag.
