During the Umayyad and Abbasid caliphates, the governor of Sind (Arabic: عامل السند‎ ‘āmil al-Sind) was an official who administered the Muslim province of Sind. The governor was the chief Muslim official in the province and was responsible for maintaining security in the region. As the leader of the provincial military, he was also in charge of carrying out campaigns against the non-Muslim kingdoms of India. Governors appointed to the region were selected either directly by the caliph, or by an authorized subordinate, and remained in office until they either died or were dismissed.
