Andrew of Hungary (, ; 1210January 1234) was Prince of Halych–Volhynia between 1227 and 1230, and between 1231 and 1234, and Prince of Zvenyhorod in 1226. Early life Andrew was the youngest (third) son of King Andrew II of Hungary and his wife, Gertrude of Merania. He was born around 1210, according to historian Gyula Kristó. Mór Wertner placed the date of his birth in the period between 1210 and 1212. He was infant, when his mother was assassinated in the autumn of 1213. His name is first mentioned by a letter of Pope Honorius III in February 1217. The infant Andrew's nanny was Alice of French origin, a lady-in-waiting of Queen Yolanda of Courtenay, his father's second spouse. His betrothal to Isabella, a daughter of Leo I, King of Cilicia was decided by their parents during his father's return from the Holy Land in early 1218. Andrew II and Leo I intended them to become joint heirs to the Armenian (Cilician) throne. Pope Honorius confirmed their engagement in 1219. However, their betrothal was later broken in favor of a more advantageous marriage between Isabella and Philip of Antioch for her bridegroom. Following his older brother Coloman was captured after Mstislav Mstislavich and his Cuman allies defeated the Hungarians near Halych in August 1221, Andrew II entered into negotiations with Mstislav and they reached a compromise in late 1221 or early 1222. The Hungarian king renounced Halych and arranged a marriage alliance between his youngest son, Andrew, and Mstislav's daughter Elena (also known as Maria) in order to secure Coloman's release. Coloman also had to abandon all claim on Halych in favor of the approximately eleven-year-old Andrew. Their father tried to obtain a papal exemption from these conditions and asked for the transfer of the royal title of Coloman to Andrew, but Pope Honorius refused the request. Prince of Halych After 1222, Andrew disappears from contemporary records in Hungary. His subsequent role in Halych as puppet ruler of his father is narrated only by the Galician–Volhynian Chronicle. Therefore, some Hungarian historians questioned the narration of the Old Ruthenian work, considering the young Andrew died in 1224 at the latest and his betrothal with Mstislav's daughter never took effect. Mór Wertner proved that a charter of Coloman implicitly suggests that Andrew was still alive around 1230 or 1231. First reign Danylo Romanovych – son-in-law of Mstislav – refused the agreement between
