Ecuador-Peru Conflict, 1941

The Second Ecuadorian–Peruvian War, usually called simply the Ecuadorian–Peruvian War, and known locally as the War of '41 (Spanish: Guerra del 41), was a South American war fought between 5 July to 2 October of 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, parts of the Andean province of Loja and all the amazon disputed territory. Although the war took place during World War II, it is unrelated to that conflict, as neither country was supported by either the Allies or the Axis. A ceasefire agreement between the two countries came into effect on 31 July 1941, but Peru soon broke it. A new ceasefire agreement came into effect on 2 October ending the clashes. Both countries signed the Rio Protocol on 29 January 1942, and Peruvian forces subsequently withdrew. Enmity over the territorial dispute continued after 1942, and the border disputes were not entirely resolved until the Cenepa War of 1995 and the signing of the Brasilia Presidential Act agreement in October 1998.
