In 1644 the Ottoman Sultan dismissed Islyam's brother Mehmed IV and placed Islyam on the throne. Islyam appointed his younger brother Kyrym as kalga. As nureddin he continued Gazi, the son of his brother Mubarak. In 1651 Kyrym was killed at the Battle of Berestechko and was replaced by Gazi, the new nureddin being Islyam's younger brother Adil. Kyrym, Mubarak and Adil were all fathers of khans. Islyam is remembered as a builder and successful administrator. He tended to appoint non-nobles without antagonizing the clan leaders. For the Ukrainian rebellion see below. In 1654 he died of natural causes.
