The Yemeni Hamdanids were a series of three families descended from the Arab Banū Hamdān tribe, who ruled in northern Yemen between 1099 and 1174. They must not be confused with the Hamdanids who ruled in al-Jazira and northern Syria in 906-1004. They were expelled from power when the Ayyubids conquered Yemen in 1174.
The first Hatimid line (Banū Ḥātim; r. 1099–1116)
The Banu’l-Qubaib line (r. 1116–1139)
The second Hatimid line (r. 1139–1174)
All the three lines (and definitely the third one) appear to have been descended from the Hamdan tribe, just like the Ismaili Sulayhid dynasty who ruled Yemen and were adherents of the Egyptian Fatimid caliphs. The Sulayhid capital was moved from San'a to Jibla in 1088, and a Hamdan tribesman called Imran bin al-Fadl was appointed governor of the city together with the king's uncle As'ad bin Shihab. When the Sulayhid da'i or leader Saba' bin Ahmad died in 1098, control over San'a passed to the powerful tribal leader Hatim bin al-Ghashim al-Mughallasi who took the title sultan. Hatim established the power of the Hamdanids together with his eldest son Muhammad. However, he soon found reason to kill his son, who was given to murdering beautiful young girls. When Hatim died in 1109, he was therefore succeeded by his second son Abdallah, who was poisoned in 1111. His younger brother Ma'n then came to power. Ma'n was deposed and imprisoned in 1116 by the qadi Ahmad, son of governor Imran, since he was too weak to uphold authority over the Hamdan sub-tribes. Hisham, al-Humas and Hatim (II), belonging to the al-Qubaib line of the Hamdanids, then maintained power until 1139. Under Hatim there was tribal discord and the people of San'a rose in revolt. The son of qadi Ahmad bin Imran, Hamid ad-Dawla Hatim, entered the city with 700 Hamdani horsemen and was established as sultan.
