Bangladesh was formed in 1971 after a bloody liberation war, which was primarily fought between the Pakistani military and the Bengali population of East Pakistan, now Bangladesh. The war followed the declaration of independence by Sheikh Mujibur Rahman, and it resulted in Bangladesh's independence after a nine-month conflict.
The year 1971 marked the creation of Bangladesh as a separate nation following its split from Pakistan, which had been formed in 1947 after the partition of India. The independence of Bangladesh was achieved with the support of India, which intervened in the war on behalf of the Bengali people.
This event was significant not only for Bangladesh but for South Asian geopolitics, marking a new chapter in the region's history.
