When did the Hapsburg monarchy end?
Habsburg Monarchy
The head of the Austrian branch of the House of Habsburg was often elected Holy Roman Emperor: from 1452 until the Empire's dissolution in 1806, Charles VII of Bavaria (1742–1745) was the only Holy Roman Emperor who was not Habsburg ruler of Austria.[6][7] The two entities were never coterminous, as the Habsburg Monarchy covered many lands beyond the Holy Roman Empire, and most of the Empire was ruled by other dynasties.
