Why did Ecuador and Peru fight a war over a base that didn't exist?
In 1981, a brief military clash erupted between Ecuador and Peru over three border outposts. Peru labeled the sites 'False Paquisha' because they were not the legal bases defined by the 1942 Rio Protocol. This strange conflict revealed deep-seated tensions that would simmer for nearly two more decades.
The Paquisha War, also known as the Paquisha Incident, began on January 22, 1981, after the Peruvian government reported an attack on an aircraft conducting surveillance near the Comaina River. Upon inspection, Peruvian forces discovered three Ecuadorian military detachments occupying territory that Peru considered its own under the 1942 Rio de Janeiro Protocol. Peruvian President Fernando Belaúnde Terry dubbed these sites 'False Paquisha' to distinguish them from the legitimate, treaty-sanctioned Paquisha base.
The dispute centered on a 78 km section of the border that remained poorly defined. Ecuador argued the Rio Protocol was inexecutable, while Peru maintained the matter was settled. Tensions escalated as both nations militarized the Cordillera del Cóndor. By February 1981, Peruvian forces had systematically recovered the occupied posts, including 'PV-22,' 'PV-3,' and 'PV-4,' eventually driving Ecuadorian troops back to the summit of the mountain range. The conflict concluded with the Sorrosa-Du Bois Act, which established a ceasefire and mandated a separation of forces.
Despite the ceasefire, the underlying territorial dispute persisted throughout the 1980s. Ecuador’s congress reaffirmed the nullity of the Rio Protocol in 1983, and both nations continued to build military infrastructure along the border. The cycle of tension eventually led to another confrontation in 1995, the Cenepa War. It was not until the 1998 Brasilia Presidential Act that Ecuador formally recognized the validity of the Rio Protocol, finally ending the long-standing territorial disagreement between the two nations.
