  Mu'awiya succeeded Ali in 661 and founded the dynastic Umayyad Caliphate, during which Alids were severely persecuted. After Ali, his followers (shi'a) recognized his eldest son Hasan as their imam. When he died in 670, likely poisoned at the instigation of Mu'awiya, the Shia community followed Hasan's younger brother Husayn, who was killed by Umayyad forces in the Battle of Karbala in 680, alongside many of his relatives. To revenge the Karbala massacre, soon followed in 685 the Shia uprising of al-Mukhtar, who claimed to represent Ibn al-Hanafiyya. The main movements that followed this uprising were the now-extinct Kaysanites and the Imamites. The Kaysanites mostly followed Abu Hashim, the son of Ibn al-Hanafiya. When Abu Hashim died around 716, this group largely aligned itself with the Abbasids, that is, the descendants of Muhammad's uncle Abbas. On the other hand, the Imamites were led by quiescent descendants of Husayn, through his only surviving son, Ali Zayn al-Abidin (d. 713). An exception was Ali's son Zayd, who led a failed uprising against the Umayyads around 740. For his followers, known as the Zaydites, any learned Hasanid or Husaynid who rose against tyranny qualified as imam.
