The Lands of the Hungarian Crown (Hungarian: A Magyar Szent Korona Országai) was the titular expression of Hungarian pretensions to the various territories that the king of Hungary ruled nominally or absolutely.
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.
The Banate of Bosnia (Serbo-Croatian: Banovina Bosna / Бановина Босна), or Bosnian Banate (Bosanska banovina / Босанска бановина), was a medieval state located in what is today Bosnia and Herzegovina. Although Hungarian kings viewed Bosnia as part of Hungarian Crown Lands, the Banate of Bosnia was a de facto independent state for most of its existence. It was founded in the mid-12th century and existed until 1377 with interruptions under the Šubić family between 1299 and 1324. In 1377, it was elevated to a kingdom. The greater part of its history was marked by a religiopolitical controversy revolving around the native Christian Bosnian Church condemned as heretical by the dominant Chalcedonian Christian churches, namely the Catholic and Eastern Orthodox churches, with the Catholic Church being particularly antagonistic and persecuting its members through the Hungarians.
