The Japanese Occupation of Singapore occurred during World War II, from February 15, 1942, to September 12, 1945. The Japanese Imperial Army invaded Singapore, which was then a British colony, and quickly defeated the British forces. This marked a significant shift in power in Southeast Asia. During the occupation, the Japanese implemented strict military rule and propaganda, leading to widespread suffering among the local population. Many people faced harsh treatment, including forced labor and imprisonment. The occupation ended when the Allies regained control, leading to Singapore's eventual return to British rule.
