This paper will study the uprising of Zaid Ibn Ali and his son, Yahya, during the last decade of the Umayyad reign. Zaid Ibn Ali invited people to join him according to the Quran and the Sira'. Initially some groups pledged their loyalty to him (bai'a). But in practice, during the movement, he was alone and lacked strong support. Also during Yahya's movement in Khurasan, the Abbasids followers did not support him, although, after his death they demand retaliation. While, long before the Zaid's movement, the Abbassids began their revolt, but during these two movements they did not cooperate, even they took out their followers from Kufeh and ordered them not to cooperate with Zaid. The article argues that the Abbasids, by 'moving in the margins', saved themselves from the dangers threatened these movements. But, during the early years of their reign, by claiming retaliation of death of Zaid and Yahya, they showed their relationship with them.
