The Sindh Muslim League was an integral pre-independence faction of the All-India Muslim League and later, in the post-independence period, a breakaway faction of the Muslim League led by Muhammad Ayub Khuhro, which existed from 1952 to 1954.
The Sindh Muslim League was conceptualized by Abdullah Haroon and Bahadur Yar Jung, but initially lacked support.
[1] But by 1938, it managed to secure seats in the newly established Sind Legislative Assembly under the leadership of Ghulam Hussain Hidayatullah by forming alliances with powerful feudal lords and Pirs.
After independence, Ayub Khuhro was the first Chief Minister of Sindh in Pakistan.
In 1952, severe in-fighting between Ayub Khuhro and some other Muslim League leaders in Sindh saw the central Muslim League leadership asking Khuhro to step down.
