Exploring the Left-wing Opposition to the One-Unit Scheme in Pakistan (1955-1970): A Focus on the Left of Sindh
Abstract

The Left in Sindh played a significant role in the movement against the One-Unit scheme. The One-Unit scheme aimed to merge all four provinces of West Pakistan into a single wing called West Pakistan to achieve parity in population between West and East Pakistan. This move essentially denied the existence of the provinces of West Pakistan. While the Sindhi nationalist parties were aligned with the Left in Sindh and actively participated in the movement, it was the leftist parties such as the Communist Party of Pakistan, Sindh Hari Committee, Hyderabad Students Federation, and Sindh National Students’ Federation that took the forefront in the movement. This paper delves into the rationale behind the One-Unit scheme and the reasons behind the anti-One Unit movement, drawing primarily from secondary sources that provide a comprehensive understanding of the major political uprisings and the significant role played by the Left in leading the anti-One Unit movement.
