The history of Colombia during World War II began in 1939. Although geographically distant from the main theaters of war, Colombia played an important role in World War II because of its strategic location near the Panama Canal, and its access to both the Atlantic and Pacific Oceans. Colombia also experienced major changes to its military and society, due to increased influence from the United States, but it was also able to maintain its sovereignty throughout the war, as well as avoid sending troops into battle.
