The Bengal famine of 1943 was an anthropogenic famine in the Bengal province of British India during World War II. An estimated 0.8–3.8 million people died, in the Bengal region, from starvation, malaria and other diseases aggravated by malnutrition, population displacement, unsanitary conditions and lack of health care. Millions were impoverished as the crisis overwhelmed large segments of the economy and catastrophically disrupted the social fabric. Eventually, families disintegrated; men sold their small farms and left home to look for work or to join the British Indian Army, and women and children became homeless migrants, often travelling to Calcutta or other large cities in search of organised relief.

The Japanese occupation of Burma was the period between 1942 and 1945 during World War II, when Burma was occupied by the Empire of Japan. The Japanese had assisted formation of the Burma Independence Army, and trained the Thirty Comrades, who were the founders of the modern Armed Forces (Tatmadaw). The Burmese hoped to gain support of the Japanese in expelling the British, so that Burma could become independent.
