Wasit - A settlement in Babylonia also known as Kashkar
Wasit was a city built in the last quarter of the 7th century AD by Al-Hajaj bin Yousif Al-Thaqafi, as an administrative centre for Iraq. Its name appears to originate from Syriac ܟܪܟܐ karḵa meaning "citadel" or "town".

It was built on the west bank of the Tigris following a flood which left the older city of Kashkar stranded on the east bank.

Wasit absorbed the population of Kashkar, which became a ghost city, only to suffer the same fate of abandonment in the 16th Century after a new flood.

Modern location: Ruins in south east of Kut in eastern Iraq
