Overview
Peru — the seat of the Spanish Viceroyalty of Peru and the stronghold of royalist power in South America — was liberated through the combined campaigns of both great liberators. José de San Martín, arriving by sea from Chile, occupied Lima and proclaimed Peruvian independence on 28 July 1821, becoming "Protector" of Peru. But royalist forces remained strong in the highlands, and after the inconclusive Guayaquil Conference with Bolívar (July 1822), San Martín withdrew.
History
The final liberation fell to Simón Bolívar and Antonio José de Sucre. Bolívar won the cavalry Battle of Junín (6 August 1824), and Sucre destroyed the last major royalist army at the Battle of Ayacucho (9 December 1824), where the Spanish viceroy surrendered — effectively ending Spanish rule in South America. Peru now became a sovereign republic.
Later history and present status
The 19th century was turbulent, dominated by caudillos and, mid-century, by a guano-export boom that funded the state. The catastrophic War of the Pacific (1879–1884) against Chile cost Peru the nitrate province of Tarapacá and years of occupation. The 20th century saw oscillation between civilian and military rule, the Shining Path (Sendero Luminoso) insurgency of the 1980s–1990s, and the authoritarian government of Alberto Fujimori (1990–2000). Recent years have been marked by extreme political instability, with seven presidents since 2016. President Dina Boluarte was impeached and removed on 10 October 2025 amid a crime wave; she was succeeded by Congress president José Jerí, who was himself removed by Congress on 17 February 2026 (by a vote of 75–24, with 3 abstentions) over undisclosed meetings with Chinese businessmen (the "Chifagate" scandal). Congressman José María Balcázar was elected by Congress to succeed Jerí on 18 February 2026, serving as interim caretaker, with general elections scheduled for 12 April 2026. [FLAG: Peru's leadership is highly fluid; the interim presidency and the April 2026 election are fast-moving.]
