Argentina: Colonial Period

The Argentina colonial period began in the early sixteenth century with Spanish colonization, though the region long remained a peripheral outpost of the Viceroyalty of Peru, governed from distant Lima. Buenos Aires, founded in 1536 and refounded in 1580 after an earlier abandonment, grew slowly; lacking the silver and gold of the Andes, the area relied instead on cattle ranching, hides, and trade routes linking the Atlantic coast to the mining center of Potosí.

In 1776, as part of the Bourbon Reforms, Spain elevated the region by creating the Viceroyalty of the Río de la Plata, with Buenos Aires as its capital and covering territory that now spans Argentina, Bolivia, Paraguay, and Uruguay. The change was driven by a desire to defend against Portuguese expansion from Brazil, counter British ambitions in the South Atlantic, and curb contraband trade. Buenos Aires subsequently grew into a flourishing Atlantic port and administrative center.

British invasions of Buenos Aires in 1806 and 1807 were repelled by local militias rather than Spanish regulars, giving the criollo population new confidence in their own capacity for self-rule. Growing frustration with Spanish trade restrictions and Bourbon administration, compounded by Spain's political crisis under Napoleon, culminated in the May Revolution of 1810, which established an autonomous local government. Formal independence followed in 1816, marking the end of Spanish colonial rule. This Argentina colonial period laid the institutional and economic foundations later inherited by the independent nation; see the Argentina country profile for broader context, and Wikipedia's overview of the Viceroyalty for further reading.
