Treaty of Lima
Lima, Peru
What happened
Peru, represented by Pedro José Rada y Gamio, and Chile, represented by Emiliano Figueroa Larraín. After the War of the Pacific, Chile had governed the Peruvian provinces of Tacna and Arica since 1883, and a promised vote on their future was never held. After years of talks with help from the United States, the two countries agreed to split the region. Tacna went back to Peru, Arica stayed with Chile, and Chile paid Peru up to US$6 million.
Why it matters
Why it matters: It settled a long dispute and fixed the border between Chile and Peru. But it disappointed Bolivia's hopes for access to the sea, which contributed to the Chaco War.
What came next
The treaty took effect on 28 August 1929, when Tacna returned to Peru. In 1999 the two countries agreed to fully carry out its terms, giving Peru port facilities in Arica.
Did you know?
Every 28 August, Tacna holds a parade with a giant Peruvian flag to celebrate its return to Peru.
