Emeric of Hungary in the context of "Andrew II of Hungary"

Andrew II (Hungarian: II. András, Croatian: Andrija II., Slovak: Ondrej II., Ukrainian: Андрій II; c. 1177 – 21 September 1235), 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 (or noblemen) 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.

Although Andrew did not stop conspiring against Emeric, the dying king made Andrew guardian of his son, Ladislaus III, in 1204. After the premature death of Ladislaus, Andrew ascended the throne in 1205. According to historian László Kontler, "[i]t was amidst the socio-political turmoil during [Andrew's] reign that the relations, arrangements, institutional framework and social categories that arose under Stephen I, started to disintegrate in the higher echelons of society" in Hungary. Andrew introduced a new grants policy, the so-called "new institutions", giving away money and royal estates to his partisans despite the loss of royal revenues. He was the first Hungarian monarch to adopt the title of "King of Halych and Lodomeria". He waged at least a dozen wars to seize the two Rus' principalities, but was repelled by the local boyars and neighboring princes. He participated in the Fifth Crusade to the Holy Land in 1217–1218, but the crusade was a failure.
