What led to the breakup of west and east Pakistan?

The breakup of West and East Pakistan in 1971 was primarily driven by deep-seated political, economic, and cultural disparities between the two regions. East Pakistan, home to the majority of the population, felt marginalized by the West Pakistani government, which was dominated by West Pakistani interests. The situation escalated after the 1970 general elections, where the Awami League in East Pakistan won a majority but was denied power, leading to widespread protests. The government’s military crackdown in March 1971 further intensified tensions, culminating in a war for independence and the creation of Bangladesh.
