The party was founded in June 1936, the same year that the Sind province had been created.
The party had as its explicit purpose to foster communal harmony between Hindus and Muslims.
[4] The party counted on the support of waderas (large-scale land-owners),[1] such as Allah Bux Soomro and Yar Muhammad Junejo.
[5] Bux stated:[5] Whatever our faiths we must live together in our country in an atmosphere of perfect amity and our relations should be the relations of the several brothers of a joint family, various members of which are free to profess their faith as they like without any let or hindrance and of whom enjoy equal benefits of their joint property.
[3] Allah Bux Soomro later served as Premier of Sindh from 23 March 1938 – 18 April 1940 until a no-confidence motion was passed against him by the Indian National Congress and Muslim League.
