Peru and the United States first established diplomatic relations in 1826, five years following the proclamation of Peruvian independence in July 1821 under General San Martin. The area that became the Republic of Peru previously had been under Spanish sovereignty. Diplomatic relations have been interrupted due to intermittent territorial disputes with its neighbors, periods of military rule, and coups that have overthrown civilian constitutional government. However, diplomatic ties have never been severed between the two countries. Peru has been a member of the United Nations since 1949.
United States Recognition of Peru, 1826.
The independence of Peru was recognized by the United States by the appointment of James Cooley as Charge d’Affaires on May 2, 1826.
United States Recognition of the Peru-Bolivian Confederation, 1838.
Following its independence from Spain, in 1836 Peru joined the Peru-Bolivian Confederation. The United States recognized the Peru-Bolivian Confederation on March 16, 1837 by the appointment of James B. Thornton as Chargé d’Affaires. Thornton was commissioned to Peru but received by the Peru-Bolivian Confederation. Succeeding Thornton, who died in Peru in January, 1838, J.C. Pickett was appointed Charge d’Affaires on June 8, 1838. He did not present his credentials until January, 1840. This lapse in diplomatic representation may be attributed to the dissolution of the Peru-Bolivian Confederation in 1839, and the return to separate U.S.-Peru diplomatic relations.
