American Popular Revolutionary Alliance

The Peruvian Aprista Party (Spanish: Partido Aprista Peruano, PAP) (listen) is a Peruvian political party and a member of the Socialist International. The party was founded as the American Popular Revolutionary Alliance (Spanish: Alianza Popular Revolucionaria Americana, APRA) by Víctor Raúl Haya de la Torre, who originally intended to create a network of anti-imperialist social and political movements in Latin America. Members are called "compañeros" (fellows), based on the fraternity espoused by Haya de la Torre.

Facing international pressure from the United States, which was promoting anti-communism in the Americas, the party is said to have adopted a mild right-wing populist agenda by the 1940s. The party later adopted in 2006 a new platform as García's second presidency implemented a series of policies labelled as center-right, embracing free-market capitalism, dialogue with other right-wing parties and organizations in the country, and closer ties with the Catholic Church and Evangelical churches. A number of scholars say that the party has shifted to the right side of the left–right political spectrum.

Founded continentally in 1924 in Mexico City, Mexico, and nationally in 1930 in Lima, it is one of the oldest political parties in Latin America. Among the Peruvian political parties in activity, specifically for having been stripped of electoral victories by coups or military governments after having triumphed democratically, it also went through two long periods of illegality, both under military and civilian governments, having been persecuted by the presidencies of Luis Miguel Sánchez Cerro and Manuel A. Odría. The Peruvian Aprista Party has gained in the presidency in two occasions: in 1985 and 2006, both under the candidacy of Alan García. At parliamentary level, the party was represented uninterrupted from 1995 until 2020, falling below the electoral threshold to attain legislative representation.

Although APRA does not operate throughout Latin America as its founder envisioned for, it has served as a powerful influence for other social democratic Latin American political organizations, such as the PT in Brazil, the Democratic Action (AD) in Venezuela and the Socialist Party of Chile.
