Viceroyalty of the Río de la Plata

Uruguay, 1776–1810. Draft, not yet reviewed

The Viceroyalty of the Río de la Plata was the last to be organised and also the shortest-lived viceroyalty of the Spanish Empire in the Americas. It was established in 1776 from several former Viceroyalty of Peru dependencies that mainly extended over the Río de la Plata Basin, roughly the present-day territories of Argentina, northern Chile, Bolivia, Paraguay and Uruguay, extending inland from the Atlantic Coast. Buenos Aires was chosen as the capital. These events proved decisive at the 1810 May Revolution events deposing Viceroy Cisneros at Buenos Aires.

Seat of power: Buenos Aires

Juan José de Vértiz y Salcedo

Viceroy of the Rio de la Plata, 1778–1784

He assumed the post of Viceroy in 1778, having had a wide set of accomplishments, developing a local economy, colonizing uninhabited lands (or inhabited by local natives), establishing local government (Intendencias) all over the viceroyalty and prepared the way to the foundation of the Real Audiencia de Buenos Aires. During his administration, he established the first city census, which at the time showed about 37,000 inhabitants. He played an important role in the repression of the uprising of Túpac Amaru II in Peru.

Nicolás Antonio de Arredondo

Viceroy of the Rio de la Plata, 1789–1795

As viceroy, he improved the layout of the streets of Buenos Aires and fortified the city of Montevideo. He created local councils and police corps, gave a boost to animal husbandry, mediated between the conflicts of business people and ranchers, and fought against contraband.

Antonio de Olaguer y Feliú

Viceroy of the Rio de la Plata, 1797–1799

During his mandate, he had to contend with the presence of British and Portuguese forces in the Río de la Plata region, as well as nascent revolutionary sentiment inspired by the recent French Revolution. He opened the port of Buenos Aires to foreign traffic in a bid to stimulate the commercial activities of the Viceroyalty, which had begun to suffer from the growing tensions between the European powers.

Gabriel de Avilés, 2nd Marquis of Avilés

Viceroy of the Rio de la Plata, 1799–1801

He was viceroy in Buenos Aires until 1801, when he was promoted to viceroy of Peru. Avilés had a reputation as a man of good character, kind and pious.

Baltasar Hidalgo de Cisneros

Viceroy of the Rio de la Plata, 1809–1810

He disestablished the government Junta of Javier de Elío and quelled the Chuquisaca Revolution and the La Paz revolution. An open cabildo deposed him as viceroy during the May Revolution, but he attempted to be the president of the new government junta, thus retaining power. The popular unrest in Buenos Aires did not allow that, so he resigned.
