This negligence by Assam and Indian government led to the foundation of the Mizo National Famine Front (MNFF), set up to provide relief to the far-flung areas. This body later became the Mizo National Front (MNF), which staged a major uprising in 1966. Under its leader Laldenga (who later became the chief minister of Mizoram), MNF fought a bitter separatist struggle for 20 years against the Indian Army until an accord that guaranteed Mizoram's autonomy as a separate state was signed in 1986.
