Muhammad II Chelebi
Muhammad II Chelebi was the fourth and last Sultan of the Eretnids. He was crowned when he was 7 years old, after his father died in August 1380 from the plague. His regent was Kadi Burhan al-Din, who proclaimed himself as the ruler by January 1381.
Sometime after Kadi Burhan al-Din's usurpation of the rule, a certain Ahi Nawruz planned the assassination of Kadi Burhan al-Din and likely agreed with Muhammad, as he planned to reinstall him as the ruler. Though this faction was promptly extinguished by Kadi Burhan al-Din, while Muhammad was spared. In the spring of 1387, dignitaries from Sivas, Sarraf Bayezid, Ahi Muhammad, Ahi Nasr al-Din, Emir-i Hajj, and a certain Christian priest, incited Muhammad to take over the throne as Kadi Burhan al-Din was away resting at a summer pasture. This revolt was repressed by one of the commanders of Kadi Burhan al-Din, who didn't view the revolt as a major threat.
According to Ibn Khaldun and Ibn Hajar al-Asqalani, Muhammad was killed by Kadi Burhan al-Din in 1390.
