Treaty of Lima (1929)

The Tacna–Arica compromise or Treaty of Lima^[a] was a series of documents that settled the territorial dispute of both Tacna and Arica provinces of Peru and Chile respectively. According to the Treaty, the Tacna-Arica Territory was divided between both countries; Tacna being awarded to Peru, with Chile retaining sovereignty over Arica. Chile also agreed to pay up to US$6 million (about £1.23 million; equivalent to $110 million in 2024) in compensation to Peru. The treaty was signed on 3 June 1929 in Lima by then-Peruvian Representative Pedro José Rada y Gamio and Chilean Representative Emiliano Figueroa Larrain.^[1]

The controversy was a direct aftermath of the War of the Pacific, a confrontation of Chile against Peru and Bolivia. Chile won the war and conquered the Peruvian territories of Tarapacá, Tacna and Arica. The defeated Peruvian government was forced to sign the Treaty of Ancón in 1883. According to this treaty, Tarapacá was annexed to Chile, and a plebiscite was meant to take place in 1893, 10 years after the signing of the treaty. The plebiscite, however, never took place, as both countries had conflicting points of view and did not reach an agreement.^[2] Chile began a campaign known as Chilenization in 1909. Peru followed in 1911 with the recalling of its ambassador and a break of diplomatic relations.^{[citation needed]}

On July 20, 1922, Chile and Peru agreed to arbitrate the dispute with the President of the United States.^[3] U.S. President Calvin Coolidge appointed, in 1925, the first U.S. arbitrator, General John J. Pershing; General William Lassiter followed in 1926. Neither negotiator was able to break the deadlock. US Secretary of State Frank B. Kellogg suggested direct negotiations in Washington, D.C. in 1928. It was these negotiations that led to the Treaty of Lima.^{[citation needed]}

Treaty

The deal that was finally reached allowed Peru to reacquire Tacna while Chile kept Arica. Chile had also to make some concessions such as building a Peruvian-administered wharf in Arica and pay a six million-dollar indemnification, among other provisions. In 1999, Chile and Peru at last agreed to fully implement the Treaty of Lima, providing Peru with access to port facilities in Arica.^[4]
