Habsburg monarchy

The Habsburg monarchy, also known as the Habsburg Empire or Habsburg Realm (/ˈhæpsbɜːrɡ/), and Danube Monarchy, was the collection of empires, kingdoms, duchies, counties and other polities (composite monarchy) that were ruled by the House of Habsburg. From 1804 it was referred to as the Austrian Empire, and from 1867 as Austria-Hungary.

The history of the Habsburg monarchy can be traced back to the election of Rudolf I as King of Germany in 1273 and his acquisition of the Duchy of Austria for the Habsburgs in 1282. In 1482, Maximilian I acquired the Netherlands through marriage. Both realms passed to his grandson and successor, Charles V, who also inherited the Spanish throne and its colonial possessions, and thus came to rule the Habsburg empire at its greatest territorial extent. The abdication of Charles V in 1556 led to a division within the dynasty between his son Philip II of Spain and his brother Ferdinand I, who had served as his lieutenant and the elected king of Hungary, Croatia and Bohemia. The Spanish branch (which held all of Iberia, the Netherlands, and lands in Italy) became extinct in the male line in 1700, but continued through the female line through the House of Bourbon. The Austrian branch (which ruled the Holy Roman Empire, Hungary, Bohemia and various other lands) was itself split into different branches in 1564 but reunited 101 years later. It became extinct in the male line in 1740, but continued through the female line as the House of Habsburg-Lorraine.
