About the Reorganisation of Assam and the Assam Accord
After independence in 1947, Assam entered a long period of territorial reorganisation. The process began with the Sylhet Referendum of 1947, through which Sylhet district went to East Pakistan. Assam then lost further territory as new states were carved out of it. On 1 December 1963, Nagaland was created as a separate state of India from the Naga hills area of Assam. Later, on 21 January 1972, Meghalaya was created as a full state from the hill districts of Assam. In the same year, 1972, the reorganisation of the north-east continued: Manipur and Tripura became full states, while Mizoram and Arunachal Pradesh (NEFA) became Union Territories. Both of these Union Territories, Mizoram and Arunachal Pradesh, became full states in 1987. As a result of these changes, Assam’s map shrank considerably from what it had been at the time of independence.
One direct administrative consequence of the 1972 reorganisation was the shift of Assam’s capital. Shillong had been the capital of Assam, but when Meghalaya became a separate state in 1972, Shillong went to Meghalaya. Assam therefore had to move its capital. The capital was shifted from Shillong to Dispur in Guwahati, and Dispur has been the official capital of Assam since 1972. Meanwhile, Shillong remained the capital of Meghalaya. This is a frequently asked fact: the reorganisation did not only change boundaries, it also changed the seat of government of Assam.
The second, and even more dramatic, part of this topic is the Assam Agitation and the Assam Accord. The Assam Agitation started in 1979 and continued for six years, from 1979 to 1985. Its main issue was the detection and deportation of illegal foreign (Bangladeshi) immigrants. In other words, the movement was primarily against the illegal immigration of foreigners, especially from Bangladesh. The agitation was led by the All Assam Students’ Union (AASU), joined by the All Assam Gana Sangram Parishad (AAGSP); the two organisations led the movement jointly. A prominent AASU leader of the agitation was Prafulla Kumar Mahanta. The movement mobilised people across Assam and became one of the most powerful mass movements in the state’s history.
The agitation ended with the Assam Accord, signed on 15 August 1985 between the Government of India and the AASU/AAGSP leaders. On behalf of the Government of India, the Accord was signed by Prime Minister Rajiv Gandhi. The Accord fixed a cut-off date of 25 March 1971 for the detection of foreigners. Under it, foreigners who had entered Assam before 1966 were to be regularised; those who came between 1 January 1966 and 24 March 1971 were to be deleted from the electoral rolls for a period of ten years and then regularised; and those who came on or after 25 March 1971 were to be detected and deported. The Accord brought the six-year agitation to an end and led to elections in Assam. The topic therefore connects the territorial reorganisation of Assam with the state’s greatest post-independence mass movement.
