The Zubayrids branch which descended from
Zubayr ibn al-Awwam, an important member of Asadi clan, were an important faction during the
Second Fitna, the second early Islamic civil war. After
Mu'awiya declared his son
Yazid to be his successor, Zubayr's son Abd Allah refused to acknowledge Yazid as the caliph in 676. In 683, Abd Allah gained control of Mecca and established a polity. After Yazid's death, Abdullah declared himself the ''Amir al-Mu'minin
(Commander of the Believers) and founded the Zubayrid Caliphate''. Soon after, Abd Allah gained control of half of Persia as well as half of Egypt. Both the Alids (family and descendants of
Ali, fourth Rashidun caliph) and the Zubayrids were two of the
Companions of the Prophet dynasties which held the most numerous lands and estates within caliphate realm. The Zubayrids regime were fond to appoint peoples with Yemeni
Azd background as governors in
al-Sham subunits. This included southern clans of
Kinda and
Kalb. == Lineage ==
