Territories Ruled by Maria Theresa

As Archduchess of Austria and Queen of Hungary and Bohemia (1740–1780), Maria Theresa ruled the Habsburg hereditary lands:

• Archduchy of Austria
• Kingdom of Hungary
• Kingdom of Bohemia
• Austrian Netherlands (modern Belgium)
• Duchy of Milan
• Banat of Temeswar
• Grand Duchy of Transylvania

She secured these through the War of Austrian Succession and pragmatic sanctions, though Silesia was lost to Prussia.
