The Catholicosate of the Armenian Apostolic Church followed its people in taking refuge outside the Armenian highlands, which had turned into a battleground of Byzantine and Seljuk contenders. Its seat was first transferred to Sebasteia in 1058 in Cappadocia, where had existed a significant Armenian population. Later, it moved to various locations in Cilicia; Tavbloor in 1062; Dzamendav in 1066; Dzovk in 1116; and Hromkla in 1149. During King Levon I's rule, the Catholicos was located in distant Hromkla. He was assisted by fourteen bishops in administering the Armenian Church in the kingdom, a number which grew in later years. The archbishops' seats were located in Tarsus, Sis, Anazarba, Lambron, and Mamistra. There existed up to sixty monastic houses in Cilicia, although the exact locations of the majority of them remain unclear.
