Abu Bakr, the first successor of Muhammad, nominated Umar as his successor on his deathbed, and there was consensus in the Muslim community to his choice. His successor, Uthman Ibn Affan, was elected by a council of electors (Majlis). But soon he was seen by some more as a "king" than as an elected leader. Uthman was killed by members of an opposition group. Then Ali took control. He was very popular with many, but he was not accepted as caliph by the governors of Egypt. Later on even some of his own guard were against him. He had two major rebellions and was assassinated after a tumultuous rule of only five years. This period is known as the Fitna, or the first Islamic civil war.
