Very little is known of the early history of the district. The Soda Rajputs, said to be descendants of Parmar Soda, are supposed to have come into this part of Sind about 1226, when they quickly displaced the rulers of the country, though, according to other authorities, they did not conquer the country from the Sumras, the dominant race, before the beginning of the 16th century. The local dynasty of the Sodas succumbed to the Kaihoras about 1750, since which period the district has been subject more or less to Sind. The Talpur mirs succeeded the Kaihoras, and built a number of forts to overawe the people, who were lawless and addicted to robbery. On the British conquest of Sind in 1843 the greater part of the district was made over to Cutch, but in 1856 it was incorporated in the province of Sind. In 1859 a rebellion broke out, which was quickly suppressed.
