Colombia–Peru War

1932–1933 · 20th century · Also known as Leticia Incident

The Colombia–Peru War was fought between September 1932 and May 1933 after Peruvian civilians and soldiers seized the Amazon river port of Leticia, which Peru had ceded to Colombia under the Salomón–Lozano Treaty. Fighting along the Putumayo and Amazon rivers ended after the assassination of Peru's president Luis Sánchez Cerro, and League of Nations mediation returned Leticia to Colombia, confirmed by the Rio de Janeiro Protocol of 1934.
