Andrew II, also known as Andrew of Jerusalem, was King of Hungary and Croatia between 1205 and 1235. He ruled the Principality of Halych from 1188 until 1189/1190, and again between 1208/1209 and 1210. He was the younger son of Béla III of Hungary, who entrusted him with the administration of the newly conquered Principality of Halych in 1188. Andrew's rule was unpopular, and the boyars expelled him. Béla III willed property and money to Andrew, obliging him to lead a crusade to the Holy Land. Instead, Andrew forced his elder brother, King Emeric of Hungary, to cede Croatia and Dalmatia as an appanage to him in 1197. The following year, Andrew occupied Hum.

The Golden Bull of 1222 was a golden bull, or edict, issued by Andrew II of Hungary. King Andrew II was forced by his nobles to accept the Golden Bull (Aranybulla), which was one of the first examples of constitutional limits being placed on the powers of a European monarch. The Golden Bull was issued at the year 1222 diet of Fehérvár. The law established the rights of the Hungarian nobility, including the right to disobey the King when he acted contrary to law. The nobles and the church were freed from all taxes and could not be forced to go to war outside of Hungary and were not obligated to finance it. This was also a historically important document because it set down the principles of equality for all of the nation's nobility. Seven copies of the edict were created, one for each of the following institutions: to the Pope, to the Knights Templar, to the Knights Hospitaller, to the Hungarian king itself, to the chapters of Esztergom and Kalocsa and to the palatine.
