It is a social movement, based on the socio-economic and political theory "Progressive Utilization Theory" (PROUT) given by Prabhat Ranjan Sarkar. Bengal or Bangalistan was divided several times in the past. The Nellie Massacre, Mandai Massacre, etc. are the examples of criminal activities done against the Bengalis in India. The Bengalis or the followers of Bangalistan movement protested the National Register of Citizens for Assam.
