In India, between 1948 and 1971, there were large scale migrations from Bangladesh to Assam. This influx of illegal migrants from Bangladesh (then East Pakistan) was on account of political turmoil and civil unrest. Even after the end of civil war and formation of Bangladesh, migration continued, though illegally. To identify illegal immigrants, the National Register of Citizens (NRC) was prepared for the first time in Assam in 1951. The Final NRC in Assam published on August 31, 2019 has created a cause of concern because it has excluded 1.9 million people, mostly poor, from its draft list.
