Lands of the Hungarian Crown

They are distinct from the Lands of the Crown of Saint Stephen, which referred to a constituent part of the territory of Austria-Hungary following the Austro-Hungarian Compromise of 1867 up until the dissolution of the empire in 1918 at the end of World War I. St. King Ladislaus I due to a dynastic crisis in Croatia, with the help of the local nobility who supported his claim managed to swiftly seize power in northern parts of the Croatian kingdom (Slavonia).

The nature of the relationship varied through time, Croatia retained a large degree of internal autonomy overall, while the real power rested in the hands of the local nobility.

[9] Although it was a part of the Hungarian Crown Lands, the Banate of Bosnia was a de facto independent state for much of its history.

However, after the fall of the revolution, the March Constitution of Austria defined the Principality of Transylvania as being a separate crown land that was entirely independent of Hungary.

However, the Kingdom of Croatia-Slavonia kept and improved its position as an autonomous realm within the Lands of the Crown of Saint Stephen.

After World War I, Transylvania was ceded to Romania and Croatia (with Slavonia) formed the State of Slovenes, Croats and Serbs (on 1 December 1918 it united with the Kingdom of Serbia to form the Kingdom of Serbs, Croats and Slovenes).
