The Brahmin dynasty, also known as the Chacha dynasty,[1] ruled the Sindh region in western Indian subcontinent, succeeding the Rai dynasty. Most of the information about its existence comes from the Chach Nama, a historical account of the Chach-Brahmin dynasty.[2]
The members of the dynasty continued to administer parts of Sindh under the Umayyad Caliphate's Caliphal province of Sind after it fell in 712. These rulers include Hullishāh and Shishah.

The casus belli for the Ummayad invasion was Sindhi pirates seizing tribute sent from the king of Serendib to the Ummayad Caliph. For the campaign Caliph Abd al-Malik ibn Marwan granted a large army to the governor Al-Hajjaj ibn Yusuf, but no attempt was made to annex Sindh due to the caliph's death. Under his son and successor Al-Walid I, the general Muhammad bin Qasim led Islamic invasion of Sindh in 712.
During the conflict local Buddhist clans who maintained loyalty to the previous Rai dynasty such as the Jats, allied themselves with the Ummayads against Dahir. The last Hindu king of Sindh Raja Dahir was killed during the battle of Aror and Sindh was annexed into the Ummayad Caliphate.[5]
