A series of uprisings and warlike conflicts led to the emergence of the Peruvian Republic, first as an independent state of the Spanish monarchy, and second to the breaking of all ties with it.

One of the first uprisings that questioned Spanish power over the Viceroyalty of Peru was the Rebellion of Tupac Amaru II in 1780.

Because Spanish colonial power in America was mainly concentrated in the Viceroyalty of Peru, the intervention of foreign forces was necessary for the revolution to be successful.

Martin's forces were successful in occupying the capital city of Lima in 1820, and Peruvian Independence was declared on 28 July 1821.

The Metropolitan Municipality of Lima unveiled a monument to admiral Abel-Nicolas Bergasse du Petit-Thouars that stands in front of the Radio Nacional del Perú headquarters.

Lima also played host to various delegations from other countries who visited to acknowledge and celebrate Peruvian Independence.
