Sind (sometimes called Scinde, Sindhi: سنڌ) was a province of British India from 1 April 1936 to 1947 and Dominion of Pakistan from 14 August 1947 to 14 October 1955.
After Pakistan's creation, the province lost the city of Karachi, as it became the capital of the newly created country.
On 1 April 1936, Sind was separated from Bombay Presidency to get the status of a province and the provincial capital was settled in Karachi.
[1] In 1948, Karachi city (2,103 km2 area) separated from Sind to form the Federal Capital Territory of Pakistan.
In 1947 due to communal tensions and partition two million Muslim muhajir migrated to Pakistan while most Sindhi Hindus fled to India.
