Hafizi Ismāʿīlīsm, the following of al-Hafiz, intimately tied to the Fatimid regime in Cairo, disappeared after the collapse of the Caliphate in 1171 and the Ayyubid invasion of southern Arabia in 1173. But the Tayyibi dawah, initiated by Arwa, survived in Yemen with its headquarters remaining in Haraz. Due to the close ties between Sulayhid Yemen and Gujarat, the Tayyibi cause was also upheld in western India and Yemen, which gradually became home to the largest population of Tayyibis, known there as Sulaymani, Dawoodi Bohra and Alavi Bohra.[citation needed]
