The Habsburg and Bourbon administrative architecture of Spanish America (16th–19th centuries) gave viceroys concentrated authority through a hierarchical, centralized system designed for control over vast distances.
The viceroy (virrey) held plenipotentiary power—executive, judicial (appeal), military (captain-general), ecclesiastical (patronato real), fiscal. Four viceroyalties: New Spain (Mexico City), Peru (Lima), New Granada (Bogotá, 1717/1739), Río de la Plata (Buenos Aires, 1776). Each a mini-kingdom.
Royal Audiencias (high courts) in each viceroyalty (Mexico, Guadalajara, Guatemala, Santo Domingo, Lima, Charcas, Quito, Bogotá, Panama, Caracas, Buenos Aires, Cuzco, Santiago) served as:
Viceroy appointed corregidores (districts: corregimientos) and alcaldes mayores (larger provinces) to:
Intendants (intendentes) — French-inspired, directly appointed by Crown, with fiscal/military/administrative authority over intendencias. Reduced viceregal patronage, increased royal revenue, professionalized administration. Tension with viceroys and audiencias.
Presidios (frontier forts) — regular troops, commanded by viceroy's appointees. Milicias — local militias (criollo officers, Indigenous/plebeian rank) for defense, order. Viceroy = Captain-General.
Crown (via viceroy) nominated bishops, collected tithes, controlled benefices. Church = ideological pillar, social service provider, landholder. Viceroy = Vice-Patron.
The system worked for 300 years because it balanced delegated absolutism with institutional checks—until Napoleonic disruption broke the imperial link.
