The Ibadi Revolt was an Ibadi Kharijite uprising that occurred in ca. 747–748 against the Umayyad Caliphate. It established the first Ibadi imamate, a short-lived state located in the Arabian Peninsula. Although the revolt failed to create a permanent Ibadi imamate, the sect was able to achieve some limited victories. As a result of the uprising, the Ibadis were allowed to retain their effective autonomy in Hadramawt, and they were to remain an influential force in southern Arabia for the next several centuries.
