Acre, Andrew did not participate in any other military actions. Instead, he collected relics, including a water jug allegedly used at the marriage at Cana, the heads of Saint Stephen and Margaret the Virgin, the right hands of the Apostles Thomas and Bartholomew and a part of Aaron's rod. If Thomas the Archdeacon's report of certain "evil and audacious men" in Acre who "treacherously passed him a poisoned drink" is reliable, Andrew's inactivity was because of illness. Andrew decided to return home at the very beginning of 1218, even though Raoul of Merencourt, Latin Patriarch of Jerusalem, threatened him with excommunication. Andrew first visited Tripoli and participated in the marriage of Bohemond IV of Antioch and Melisende of Lusignan on 10 January. From Tripoli, he travelled to Cilicia, where he and Leo I of Armenia betrothed Andrew's youngest son, Andrew, and Leo's daughter, Isabella. Andrew proceeded through the Seldjuk Sultanate of Rum before arriving in Nicaea (now İznik, Turkey). His cousins (the sons of his uncle, Géza) attacked him when he was in Nicaea. He arranged the marriage of his oldest son, Béla, to Maria Laskarina, a daughter of Emperor Theodore I Laskaris. When he arrived in Bulgaria, Andrew was detained until he "gave full surety that his daughter would be united in marriage" to Ivan Asen II of Bulgaria, according to Thomas the Archdeacon. Andrew returned to Hungary in late 1218. Andrew's "crusade had achieved nothing and brought him no honor", according to historian Thomas Van Cleve. Oliver of Paderborn, James of Vitry and other 13th-century authors blamed Andrew for the failure of the crusade. Stephen Donnachie says that "...from examining Honorius’s registers and the diplomatic communications between Andrew and the papal curia, Andrew’s genuine commitment to the crusade should not be doubted nor his extensive preparations for the campaign dismissed, even if he did ultimately bungle his opportunity." Golden Bull (1218–1222) When he returned to Hungary, Andrew complained to Pope Honorius that his kingdom was "in a miserable and destroyed state, deprived of all of its revenues." A group of barons had even expelled Archbishop John from Hungary. Andrew was in massive debt because of his crusade, which forced him to impose extraordinarily high taxes and debase coinage. In 1218 or 1219, Mstislav Mstislavich invaded Halych and captured Andrew's son, Coloman. Andrew compromised with Mstislavich. Coloman was released, and Andrew's youngest son and namesake was betrothed to Mstislavich's
