The Sulaymanids was a sharif dynasty from the line of Muhammad's grandson Hasan bin Ali which ruled around from 1063 to 1174. Their centre of power lay in Harad in the Central Tihama of Hajjah in Yemen, due to Zaydi expansion in Hajjah the Sulaymanids sphere of influence was concentrated in Northern Tihama & Asir which was previously counted to Yemen known as Al-Mekhlaf Al-Sulaymani (The Sulaymani region).
