history of sindh

Prehistoric period

 

The original inhabitants of ancient Sindh were believed to be aboriginal tribes speaking languages of the Indus Valley civilization around 3000 BC.

Location of the Indus Valley civilization

The Indus Valley Civilization went into decline around the year 1700 BC for reasons that are not entirely known, though its downfall was probably precipitated by a massive earthquake that dried up the Ghaggar River. The Indo-Aryans are believed to have founded the Vedic civilization that existed between the Sarasvati River and Ganges river around 1500 BC. This civilization helped shape subsequent cultures in South Asia.
In his book Kitab-ul-Hind, the Persian scholar Abū Rayhān Bīrūnī (Al-Beruni) declared that even before the advent of Islam into Sindh (711 A.D.), the Sindhi language was prevalent in Sindh.
