By the late 1930s, the princely state of Manipur negotiated with the British administration its preference to be part of India, rather than Burma.[page needed] These negotiations were cut short with the outbreak of World War II. On 21 September 1949, Maharaja Budhachandra signed a Treaty of Accession merging the kingdom into India.

Over 2010–2013, the militant insurgency was responsible for the violent death of about 1 civilian per 100,000 people, each year. The world's average annual death rate from intentional violence has been 7.9 per 100,000 people.
