محمد بن القاسم الثقفي
In 711 AD, Muhammad bin Qasim led an Umayyad force of 20,000 cavalry and 5 catapults. Muhammad bin Qasim defeated the Raja Dahir and captured the cities of Alor, Multan and Debal. Sindh became the easternmost State of the Umayyad Caliphate and was referred to as "Sind" on Arab maps, with lands further east known as "Hind". Muhammad bin Qasim built the city of Mansura as his capital; the city then produced famous historical figures such as Abu Mashar Sindhi, Abu Ata al-Sindhi, Abu Raja Sindhi. At the port city of Debal, most of the Bawarij embraced Islam and became known as Sindhi Sailors, who were renowned for their navigation, geography and languages. After Bin Qasim left, the Arab Caliphate ruled Sindh through the Governors.
