This is a broad category for people who ruled Austria in a monarchical capacity; presidents and other republican rulers should not go here.

Austria was a margraviate from 976 to 1156, a duchy from 1156 to 1457, and an archduchy from 1457 to 1804. Throughout this period, Austria was a constituent state of the Holy Roman Empire. During the archduchy period, most of the Holy Roman Emperors also held the title of Archduke of Austria. In 1804, the Holy Roman Emperor Francis II proclaimed Austria an empire itself, and two years later, dissolved the Holy Roman Empire. The ruler of Austria was the Emperor of Austria until 1918. In 1867, the Empire of Austria was united with the Kingdom of Hungary. That union dissolved in 1918 after World War I, and Austria became a republic.
