Treaty of Ancón

Categories: History of Chile | History of Peru | Treaties

The Treaty of Ancón was signed by Peru and Chile on 20 October 1883, in the district of Ancón, Lima. It was intended to settle the two nations' remaining territorial differences at the conclusion of their involvement in the War of the Pacific and to stabilise post-bellum relations between them.

Under the treaty's terms, Chile gained control over the province of Tarapacá. Chile was also to occupy the provinces of Tacna and Arica for ten years, after which a plebiscite would be organised to determine their nationality. However, for several decades following the two countries were unable to reach agreement on the terms the plebiscite.

Finally, in 1929, through the mediation of the United States under President Herbert Hoover, an accord was reached. Under the Tacna-Arica compromise, Chile kept Arica, while Peru reacquired Tacna and received USD $6 million indemnity and other concessions.
