The Kingdom of Croatia (Croatian: Kraljevina Hrvatska; Latin: Regnum Croatiae; Hungarian: Horvát Királyság, German: Königreich Kroatien) was part of the Lands of the Hungarian Crown, but was subject to direct Imperial Austrian rule for significant periods of time, including its final years. Its capital was Zagreb. It was also a part of the lands of the Habsburg monarchy from 1527, following the Election in Cetin, and the Austrian Empire from 1804 to 1867.
The Kingdom of Croatia had large territorial losses in wars with the Ottoman Empire in the 16th century.
