In 1071 Erzincan was absorbed into the Mengüçoğlu under the Seljuk Sulëiman Kutalmish. Marco Polo, who wrote about his visit to Erzincan, said that the "people of the country are Armenians" and that Erzincan was the "noblest of cities" which contained the See of an Archbishop. In 1243 it was destroyed in fighting between the Seljuks under Kaykhusraw II and the Mongols. However, by 1254 its population had recovered enough that William of Rubruck was able to say an earthquake had killed more than 10,000 people. During this period, the city reached a level of semi-independence under the rule of Armenian princes.
