Bashmurian revolts (Coptic: ⲡⲓⲧⲱⲟⲩⲛ ⲙ̀ⲡⲓϣⲁⲙⲏⲣ, Arabic: ثورة البشموريين) were a series of revolts by the Egyptians in the Bashmur region in the north of the Nile Delta against the Umayyad and Abbasid Caliphates in the eighth and ninth centuries. Exactly how many revolts there were cannot be determined, but the major military conflicts took place in 749, 767 and 831–832.
