While Sunnis regard Umar ibn al-Khattab in high esteem and respect his place as one of the "Four Righteously Guided Caliphs", the Shia do not view him as a legitimate leader of the Ummah and believe that Umar and Abu Bakr conspired to usurp power from Ali. Shia believe that the Sunni view of Umar was created by the later Umayyad dynasty to honour the man that gave power to the first Umayyad ruler and third Sunni Caliph, Uthman. In this way, it gives legitimacy to Umar's consultation that started their own dynasty.
