Ecuadoran-Peruvian Border War [1941]

South American border war fought between 5–31 July 1941. It was the first of three military conflicts between Ecuador and Peru during the 20th century. During the war, Peru occupied the western Ecuadorian province of El Oro and parts of the Andean province of Loja. Although the Ecuadorian–Peruvian War occurred during World War II, it was not part of the conflict; Ecuador and Peru were neither affiliated with nor supported by the Allies or the Axis.
