Serendib (old name) in the context of "Raja Dahir"

Raja Dahir (663–712) was the last Hindu Maharaja of Sindh from 695 to 712. A Brahmin ruler, his kingdom was invaded in 711 by the Arab Umayyad Caliphate, led by Muhammad bin Qasim, where Dahir died. According to the Chach Nama, the Umayyad campaign against Dahir was due to a pirate raid off the Sindh coast that resulted in gifts to the Umayyad caliph from the king of Serendib (old name of Sri Lanka) being stolen.

Raja Dahir was born in 663 into the Brahman dynasty of Sindh, a family deeply rooted in Hindu traditions and governance. His father, Chach of Aror, who ruled from 631 to 671, was a Brahmin who ascended to the throne after marrying the widowed Queen Suhandi. This event established the Chach dynasty, which would rule Sindh for nearly a century.
