The Principality of Transylvania, from 1765 Grand Principality of Transylvania, was a realm of the Hungarian Crown and since 1804 an Austrian crownland ruled by the Habsburg and Habsburg-Lorraine monarchs of the Habsburg Monarchy (later Austrian Empire). During the Hungarian Revolution of 1848, the Hungarian government proclaimed union with Transylvania in the April Laws of 1848 (after the Transylvanian Diet's confirmation on 30 May and the king's approval on 10 June that Transylvania again become an integral part of Hungary, an initiative rejected by the Romanians and Saxons who formed the majority population of Transylvania). After the failure of the revolution, the March Constitution of Austria decreed that the Principality of Transylvania be a separate crown land entirely independent of Hungary. In 1867, as a result of the Austro-Hungarian Compromise, the principality was reunited with Hungary proper.
