Juan José Castelli was an Argentine lawyer and revolutionary leader prominent in the May Revolution and an original member of the Primera Junta. A central figure in the early stages of the Argentine War of Independence, he combined legal training with Enlightenment ideas to advocate political change across the Viceroyalty of the Río de la Plata, notably directing campaigns in Upper Peru and implementing radical measures in occupied territories.

Early life and education

Born in Buenos Aires into a family of merchant and Creole roots, Castelli studied at the Real Colegio San Carlos before attending the University of Chuquisaca in Charcas and later the University of Salamanca in Spain. Influenced by the works of Montesquieu, Rousseau, Voltaire, and Adam Smith, he read pamphlets circulating from the French Revolution and the American Revolution, connecting ideas from the Enlightenment with local grievances against the Bourbon Reforms and the Spanish Empire. During studies he became acquainted with figures tied to the Ilustración and networks that included students from Lima, Cuzco, Córdoba, and Montevideo.

Political and legal career

Returning to Buenos Aires, Castelli established a practice as a procurador and engaged in public debates in salons frequented by members of the Sociedad Patriótica and the Lodge of Lautaro. He served in municipal bodies connected to the Cabildo of Buenos Aires and maintained correspondence with leaders in Santiago, Caracas, Bogotá, and Mexico City. His legal interventions touched on cases involving merchants from Cadiz, officials from the Viceroyalty of the Río de la Plata, and clergy associated with Order of Saint Augustine and Jesuits networks. Castelli's alliances included interactions with Manuel Belgrano, Mariano Moreno, Cornelio Saavedra, Hipólito Vieytes, and Juan José Paso.

Role in the May Revolution and Primera Junta

During the crisis following the Napoleonic invasion of Spain and the deposition of Ferdinand VII of Spain, Castelli was a leading voice in the meetings preceding the May Week. He advocated immediate removal of the Viceroy Baltasar Hidalgo de Cisneros and helped shape the program of the Primera Junta, collaborating with Mariano Moreno, Cornelio Saavedra, Juan Larrea, and Manuel Belgrano. As a vocal proponent of delegitimizing the Junta Grande opponents and implementing decrees inspired by French Revolutionary Calendar ideas and British trade liberalization, he worked to extend the authority of the Junta to provinces such as Salta, Mendoza, San Juan, and Córdoba.

Military campaigns and actions in Upper Peru

Appointed as a political and military commissioner, Castelli led expeditions into Upper Peru (modern Bolivia), confronting royalist forces linked to commanders like José Manuel de Goyeneche and defenders in Potosí and Charcas. He ordered the trial and execution of prominent royalist and clerical figures, actions that drew criticism from conservative elements in Buenos Aires and ecclesiastical authorities such as bishops from La Plata and officials tied to the Spanish Inquisition legacy. His campaigns intersected with the careers of officers like Antonio González Balcarce, Juan José Viamonte, Manuel Belgrano, and opponents backed by Lima and Callao garrisons. Castelli implemented reformist measures in occupied cities, promoting secularization akin to reforms seen under Joseph Bonaparte in Spain and inspired by policies from Napoleon Bonaparte's era.

Later life, arrest, and exile

Following setbacks in Upper Peru, including defeats faced by allied forces and a strategic retreat influenced by royalist advances and logistical challenges, Castelli was recalled to Buenos Aires where political rivals within the Primera Junta and conservative factions opposed his methods. Accused of excesses and coordination failures, he suffered political isolation as figures such as Cornelio Saavedra and moderates associated with the Junta Grande moved against the radical leadership linked to Mariano Moreno. Arrested amid factional disputes, he was deported toward San Juan and later escorted to Santiago del Estero where illness overtook him. Castelli died in exile, his health undermined by infection and hardships similar to those experienced by other revolutionary exiles like Miguel de Azcuénaga and Juan Martín de Pueyrredón.

Political ideas and legacy

Castelli's thought fused influences from Enlightenment authors and revolutionary constitutions such as the United States Constitution and the French Constitution of 1793, arguing for political representation, civil liberties, and the removal of colonial privileges held by institutions like the Spanish Crown and sections of the Catholic Church. His measures in Upper Peru remain debated among historians examining secularization, anticlericalism, and revolutionary justice in the contexts of Latin American independence movements alongside contemporaries like Simón Bolívar, José de San Martín, Bernardino Rivadavia, Esteban Echeverría, and Manuel Belgrano. Monuments, biographies, and historiography in institutions such as the National Historical Museum, university departments at the University of Buenos Aires, and archives in Salta and Sucre continue to reassess his role, situating him within broader narratives of the Argentine War of Independence, regional uprisings, and the transatlantic circulation of revolutionary ideas.
