Treaty of Ancón

1883 · 19th century · Part of the War of the Pacific

The Treaty of Ancón, signed on 20 October 1883, ended the war between Chile and Peru in the War of the Pacific. Peru ceded the nitrate province of Tarapacá to Chile, while Tacna and Arica were to remain under Chilean control for ten years, followed by a plebiscite. The plebiscite was never held, and the dispute was settled only by the Treaty of Lima of 1929.
