Relations have remained sour because of the war. In 1975, both countries were at the brink of war, only a few years before the centennial of the War of the Pacific. The conflict was fueled by ideological disputes: Peruvian General Juan Velasco was a left-winger while Chilean General Augusto Pinochet was a right-winger. Velasco, backed by Cuba, set the date for invasion on August 6, the 150th independence anniversary of Bolivia, and the proposed date when Chile intended to grant this country with a sovereign corridor north of Arica, in former Peruvian territory, transfer not approved by Peru. However, he was successfully dissuaded from starting the invasion on that date by his advisor, General Francisco Morales Bermúdez, whose original family was from the former Peruvian (currently Chilean) region of Tarapacá. Velasco later fell ill and was deposed by a group of generals who proclaimed Morales Bermúdez president on August 28.
