The Fourth Five Year Plan period in India was from 1969 to 1974.
The 1971 Indo-Pak War (also known as the Bangladesh Liberation War) was a significant military conflict that resulted in the creation of Bangladesh (formerly East Pakistan).
The war lasted for 13 days (December 3-16, 1971) and is considered one of India's most decisive military victories.
The Fourth Five Year Plan faced several challenges during this period, including the war and the influx of refugees from East Pakistan.
Despite these challenges, the plan continued with its focus on growth of agriculture to achieve self-sufficiency in food, and to increase agricultural production to meet the requirements of industry and exports.
The war had economic implications for India, as military expenditures increased during this period, affecting some of the planned economic priorities.
