South America Major (1768–1779 CE): Post-Jesuit Reforms, Economic Continuity, and Rising Social Unrest

Between 1768 and 1779 CE, South America Major—encompassing all lands north of the Río Negro, extending across the full continental span of Brazil, Uruguay, Paraguay, northern Argentina and northern Chile, Bolivia, Peru, Ecuador (excluding the Cape lands at the Isthmian boundary), Colombia (excluding the Darién region, which belongs to Isthmian America), Venezuela, Guyana, Suriname, and French Guiana—experienced sustained economic prosperity amidst ongoing repercussions from the Jesuit expulsions. This era was marked by intensified Bourbon reforms in Spanish territories, administrative tightening in Portuguese Brazil, continued indigenous resistance, and the first significant stirrings of unrest among colonial populations, laying foundations for future independence movements.

Political Developments

Intensified Bourbon Reforms in Spanish America

The Spanish Crown significantly accelerated Bourbon reforms, aiming to centralize administration, increase taxation efficiency, and tighten political control across the Viceroyalty of Peru and other territories. Administrative reforms sought to diminish regional autonomy, particularly affecting local elites and religious institutions.

Continued Portuguese Administrative Tightening

Portuguese colonial governance further centralized control in Brazil, maintaining economic prosperity through gold mining and plantation agriculture, while imposing stronger regulations and taxation measures following the earlier expulsion of Jesuits.

Aftermath of Jesuit Expulsion

The Jesuit expulsions continued to reshape governance, particularly in areas formerly under Jesuit control, notably Paraguay, Uruguay, and surrounding Guaraní regions. Colonial authorities struggled to reorganize these territories, increasing tensions, instability, and indigenous vulnerability.

Economic Developments

Sustained Mining Prosperity

Gold extraction in Brazil’s Minas Gerais remained strong, underpinning Portuguese economic prosperity, while silver production at Bolivia’s Potosí continued supporting Spanish colonial economies and global trade links.

Plantation Agriculture and Slave Labor Dependency

Plantation economies, especially sugar cultivation in Brazil, remained economically vibrant and heavily reliant on enslaved African labor. This continued driving demographic shifts and reinforcing the importance of Brazil’s role in Atlantic commerce.

Continued Expansion of Ranching Economies

Livestock ranching economies further flourished in Argentina, Uruguay, Paraguay, and southern Brazil, maintaining regional economic stability, rural growth, and influencing long-term settlement patterns.

Cultural and Technological Developments

Disrupted Jesuit Legacy and Cultural Adjustments

The dismantling of Jesuit missions continued profoundly affecting indigenous cultural life, education, and social stability. While many mission communities faced decline, the cultural and educational legacies—particularly in music, crafts, agriculture, and literacy—endured and influenced broader cultural patterns.

Urban Prosperity and Architectural Achievements

Urban centers—including Lima, Quito, Bogotá, Salvador, and Rio de Janeiro—continued flourishing, showcasing colonial wealth, cultural vibrancy, and architectural sophistication. Public buildings, religious institutions, and urban infrastructure reflected sustained prosperity.

Social and Religious Developments

Social Instability Following Jesuit Expulsions

The removal of Jesuits intensified social instability, particularly among indigenous communities formerly protected within reductions. Exploitation, displacement, and social fragmentation became more pronounced, generating resentment and tensions within colonial societies.

Entrenched and Evolving Social Hierarchies

Rigid racial and class hierarchies persisted, increasingly challenged by growing social and economic tensions. European elites remained dominant, indigenous populations faced heightened vulnerability, and enslaved and mixed-race populations navigated systemic inequalities and marginalization.

Indigenous Resistance and Frontier Conflicts

Indigenous resistance remained vigorous, particularly among frontier groups such as the Mapuche in Chile, Andean indigenous communities, Amazonian peoples, and former Jesuit-protected Guaraní populations, whose resistance increasingly shaped colonial military, diplomatic, and administrative strategies.

Long-Term Consequences and Historical Significance

The era from 1768 to 1779 CE was pivotal in deepening colonial reforms, economic prosperity, and social complexities across South America Major. The ongoing consequences of Jesuit expulsions continued reshaping social structures and indigenous relations, while intensified Bourbon and Portuguese reforms inadvertently set the stage for increased political unrest. These combined tensions and transformations would prove critical precursors to subsequent independence movements and profound societal changes in the late eighteenth and early nineteenth centuries.
