Congress of Tacna

1837 · 19th century · Also known as Pact of Tacna

The Pact of Tacna was the agreement of May 1837 by which delegates of the North Peruvian Republic, the South Peruvian Republic and Bolivia defined the Peru–Bolivian Confederation. It made Andrés de Santa Cruz Supreme Protector for ten years, with control of foreign affairs and the army. Opposition in all three states to its centralising terms weakened the confederation before its defeat in 1839.
