Cenepa War

The Cenepa War (January 26 – February 28, 1995), also known as the Alto Cenepa War, was a brief and localized military conflict between Ecuador and Peru, fought over control of a disputed area on the border between the two countries. The two nations had signed a border treaty following the Ecuadorian–Peruvian War of 1941, but Ecuador later disagreed with the treaty as it applied to the Cenepa and Paquisha areas, and in 1960 Ecuador declared the treaty null and void.

The indecisive outcome of the Cenepa War — both sides claim victory — along with the mediation efforts of Argentina, Brazil, Chile and the United States, paved the way for the opening of diplomatic negotiations that ultimately led to the signing of a definitive peace agreement in 1998, putting an end to one of the longest territorial disputes in the Western Hemisphere.
