Hamdanids (Yemen)
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.
