The correct answer is: b) The 1971 Bangladesh Liberation War.
Meghalaya witnessed significant migration from East Pakistan (now Bangladesh) during the 1971 Bangladesh Liberation War. The war was fought between the government of Pakistan and the Bengali nationalist Mukti Bahini, with India supporting the latter. The war resulted in the creation of Bangladesh as an independent country.
The migration of people from East Pakistan to Meghalaya during the war was due to a number of factors. First, the war caused widespread displacement and suffering in East Pakistan. Many people were forced to flee their homes due to the fighting, and many others were killed or injured. Second, the war led to a breakdown of law and order in East Pakistan. This made it difficult for people to live in the country, and many people fled to neighboring countries, including India. Third, the Indian government encouraged the migration of people from East Pakistan to India. The Indian government saw the migration as a way to weaken Pakistan and to support the creation of Bangladesh.
The migration of people from East Pakistan to Meghalaya had a significant impact on the state. The influx of refugees put a strain on the state’s resources, and it also led to social and political tensions. However, the migration also had some positive effects. The refugees brought with them new skills and ideas, and they helped to boost the state’s economy.
The migration of people from East Pakistan to Meghalaya is a complex and controversial issue. However, it is an important part of the state’s history.
The other options are incorrect because:
a) The 1947 Partition of India did not result in significant migration from East Pakistan to Meghalaya.
c) The 1965 Indo-Pak War did not result in significant migration from East Pakistan to Meghalaya.
d) Periods of economic hardship in East Pakistan did result in some migration from East Pakistan to Meghalaya, but this was not on the same scale as the migration that occurred during the 1971 Bangladesh Liberation War.
