The Assam Movement (or Assam Agitation) (1979-1985) was a popular movement against illegal immigrants in Assam. The movement, led by All Assam Students Union (AASU) and the 'All Assam Gana Sangram Parishad' (AAGSP), developed a program of protests and demonstration to compel the Indian government to identify and expel illegal, (mostly Bangladeshi), immigrants and protect and provide constitutional, legislative and administrative safeguards to the indigenous Assamese people. The agitation programs were largely non-violent, but the Nellie massacre was a case of extreme violence. The agitation program ended in August 1985 following the Assam Accord, which was signed by leaders of AASU-AAGSP and the Government of India.
