daughter. In 1220, a group of lords persuaded Andrew to make his eldest son, Béla, the duke of Croatia, Dalmatia and Slavonia. Andrew employed Jews and Muslims to administer royal revenues, which caused a discord between Andrew and the Holy See starting in the early 1220s. Pope Honorius urged Andrew and Queen Yolanda to prohibit Muslims from employing Christians. Andrew confirmed the privileges of clergymen, including their exemption from taxes and their right to be exclusively judged by church courts, but also prohibited the consecration of udvornici, castle folk and other serfs in early 1222. However, a new conflict emerged between Andrew and the Holy See after he persuaded Béla to separate from his wife, Maria Laskarina.

A significant difference between them is that, in England, the settlement strengthened the position of all the royal subjects but, in Hungary, the aristocracy came to dominate both the crown and the lower orders.

The following year, Pope Honorius urged Andrew to launch a new crusade. If the report of the Continuatio Claustroneuburgensis is reliable, Andrew took the cross to show that he intended to launch a new crusade, but no other sources mention this event.
