Ecuadorian–Peruvian War (1857–1860)
The Ecuadorian–Peruvian War took place between 1857 and 1860. The conflict began when Ecuador attempted to sell Amazon basin land claimed by Peru in order to settle a debt with British creditors. When diplomatic relations between the two countries broke down, prior to the fragmentation of the Ecuadorian government into several competing factions, the Peruvian government ordered a blockade of Ecuador's ports in order to force the cancellation of the sale, and the official acknowledgement of Peruvian ownership of the disputed territories. By late 1859, control of Ecuador was consolidated between General Guillermo Franco, in the city of Guayaquil, and a provisional government in Quito headed by Gabriel García Moreno. Peruvian President Ramón Castilla sailed to Guayaquil with several thousand soldiers in October 1859, and negotiated the Treaty of Mapasingue with General Franco in January 1860. The signing of the treaty indicated Ecuadorian compliance with all of Peru's demands, and temporarily marked the end of the territorial dispute between the two countries. However, in September 1860, the forces of the provisional government, commanded by García Moreno and General Juan José Flores defeated Franco's government at the Battle of Guayaquil, ending the civil war in Ecuador. The new government disavowed the Treaty of Mapasingue, followed shortly afterwards by its Peruvian counterpart; this re-opened the territorial dispute.
