Sulayhid dynasty

The Sulayhid dynasty (Arabic: بَنُو صُلَيْح, romanized: Banū Ṣulayḥ, lit. 'Children of Sulayh') was an Ismaili Shi'ite Arab dynasty established in 1047 by Ali ibn Muhammad al-Sulayhi that ruled most of historical Yemen at its peak. The Sulayhids brought to Yemen peace and a prosperity unknown since Himyaritic times. The regime was confederate with the Cairo-based Fatimid Caliphate, and was a constant enemy of the Rassids - the Zaidi Shi'ite rulers of Yemen throughout its existence. The dynasty ended with Arwa al-Sulayhi affiliating to the Taiyabi Ismaili sect, as opposed to the Hafizi Ismaili sect that the other Ismaili dynasties such as the Zurayids and the Hamdanids adhered to.
