Napoleon Bonaparte’s 1807 invasion of Spain and Portugal set in motion a transatlantic imperial crisis that, within two decades, resulted in Spain’s losing nearly all of its American possessions. Typically, the founding of most Spanish South American nations is attributed to the heroic leadership of the great liberators: Simón Bolívar and José de San Martín. While San Martín is most famous for organizing the Army of the Andes that carried out the liberation of Chile, parts of Peru, and eventually, in 1822, reunited with Bolívar in Ecuador, his time in western Río de la Plata building his army is less understood. From 1814 until 1817, General San Martín took up residence in the western Río de la Plata (Argentina) city of Mendoza to build an army capable of defeating Spanish rule in Chile and Peru. To receive permission to cross the Andes westward into Chile, San Martín needed more than soldiers well trained in European military style and horses: he needed to negotiate with the local Pehuenche people—part of the broader Mapuche peoples of southern Chile and western Río de la Plata—who had successfully resisted Spanish conquest for centuries.
Before San Martín could cross the Andes to invade Chile, he participated in two interethnic diplomatic rituals known as parlamentos in Spanish and koyang in Mapudungun, with the Pehuenche. Nearly forty recorded Spanish–Mapuche parlamentos had taken place in Chile and near Mendoza since 1593. In the two 1816 parlamentos, interpreters translated the negotiations between Pehuenche representatives and San Martín over the exchange of horses, the giving of gifts, the recognition of Pehuenche dominion, and permission for the Army of the Andes to cross the mountains west to Chile. While San Martín chose to spread news of this agreement to confuse the Spanish forces in Chile as to the location of their crossing, opting not to cross Pehuenche lands, these parlamentos nevertheless speak to the power and importance of Pehuenche political traditions during the Age of Revolution.
