Sind was an administrative division of the Umayyad Caliphate and later of the Abbasid Caliphate in post-classical India, from around 711 CE with the Umayyad conquest of Sindh by the Arab military commander Muhammad ibn al-Qasim, to around 854 CE with the emergence of the independent dynasties of the Habbarid Emirate and the Emirate of Multan. The "Governor of Sind" was an official who administered the caliphal province over what are now Sindh and South Punjab in Pakistan, with Makran in Balochistan also usually being under his control.
