Feeling the need to preserve his power, Hasan-Jalal traveled twice to Karakorum, the capital of the Mongol empire, where he was able to obtain special autonomy rights and privileges for himself and the people under his domain from the ruling "khan". Despite this arrangement, the Mongols viewed many of the people of the region with contempt and taxed them excessively. Arghun Khan, the regional Mongol "ostikan" at the time, placed so many restrictions against Armenians that it prompted Hasan-Jalal in 1256 to journey to the capital once more to protest against the encroachments upon Catholicos Nerses. In response, Batu Khan drafted a document "guaranteeing freedom for Lord Nerses, Katolikos of Albania, for all his properties and goods, that he be free and untaxed and allowed to travel freely everywhere in the dioceses under his authority, and that no one disobey what he said."
