With the assistance of the pagans, Duke Vazul's son, Andrew, who had been living in exile in the Kievan Rus' and had been baptized there, seized power and was crowned; thus, a member of a collateral branch of the dynasty seized the crown. King Andrew I (1046–1060) managed to pacify the pagan rebels and restore the position of Christianity in the kingdom. In 1048, King Andrew invited his younger brother, Béla to the kingdom and conceded one-third of the counties of the kingdom "(Tercia pars regni)" in appanage to him. This dynastic division of the kingdom, mentioned as the first one in the "Chronicon Pictum" "(prima regni huius divisio)", was followed by several similar divisions during the 11th through 13th centuries, when parts of the kingdom were governed by members of the Árpád dynasty. In the 11th century, the counties entrusted to the members of the ruling dynasty did not form a separate province within the kingdom, but they were organized around two or three centers. The dukes governing the "Tercia pars regni" accepted the supremacy of the kings of Hungary, but some of them (Béla, Géza and Álmos) rebelled against the king in order to acquire the crown and allied themselves with the rulers of the neighboring countries.
