The origins of APRA in Cajamarca, 1928–1935⋆

From its foundation in 1930 until the late 1980s, the Alianza Popular Revolucionaria Americana (APRA) comprised the largest and best organised political party in Peru, but surprisingly few studies exist on how the organisation was established and built up a mass following at the provincial level. This article examines the birth of APRA in the Andean department of Cajamarca. It highlights the support the organisation obtained among key middle–class groups (i.e. lawyers, schoolteachers, cattle dealers, etc.), and the links they forged with the rural and urban poor. APRA's efforts to mobilise “new” social actors, such as women and students, are also described.
