Royal Hungary

Royal Hungary refers to the western and northern parts of the Kingdom of Hungary that remained under Habsburg rule after the country's trisection in the 16th century. Following the Battle of Mohács in 1526, Hungary was divided into three parts: Royal Hungary, the principality of Transylvania (a vassal of the Ottoman Empire), and Turkish Hungary, which was directly incorporated into the Ottoman Empire.

Royal Hungary, though smaller and less resource-rich, maintained its own constitution and institutions. It was characterized by a defensive system of fortresses along the border with Ottoman-controlled territory. The region experienced religious conflict, with the Reformation gaining a strong foothold, and faced challenges from both Ottoman incursions and internal political divisions. Despite these struggles, Royal Hungary remained a distinct entity within the Habsburg dominions for over a century and a half.12
