In 1884 Chile emerged from the War of the Pacific as a potential threat to the hegemony of the United States. The Chilean navy, then the strongest fleet in the Pacific, was able to confront American policy. In 1882 Chile refused US mediation in the War of the Pacific. In 1885, as the United States Navy occupied Colón, then part of Colombia, the Chilean government ordered its navy to occupy Panama City and not to leave until after the American forces evacuated Colon. Finally in 1888 Chile annexed Easter Island, located some 2,000 miles west of Valparaíso, and by occupying Easter Island, Chile joined the imperial nations.
