During the British Raj era, Morvi State was one of several princely states governed by the Jadeja dynasty of Rajputs. It was classified as an 11-gun salute state.[3] The Machchhu dam failure or Morbi disaster was a dam-related flood disaster which occurred on 11 August 1979, in India. The Machchu-2 dam, situated on the Machhu river, burst, sending a wall of water through the town of Morbi in the Morbi district of Gujarat, India. Estimates of the number of people killed vary greatly ranging from 1800 to 25000 people.
