Vivanco–Pareja Treaty
The Vivanco–Pareja Treaty was a treaty between Peru and Spain, signifying cooperation between the two nations during the Chincha Islands War. It was signed on January 27, 1865, on board the frigate Villa de Madrid, by Manuel Ignacio de Vivanco and José Manuel Pareja.
As a consequence, on November 7, 1865, because of his unwillingness to declare war against Spain and his discredit for having signed the treaty, Peruvian President Juan Antonio Pezet was forced out of office and replaced by his vice president, General Pedro Diez Canseco.
