Cisplatine War

1825 CE – 1828 CE · 3 years

The Cisplatine War, also called the Argentine-Brazilian War, was fought in 1825–1828 over the Banda Oriental, now Uruguay. The Empire of Brazil and the United Provinces of the Río de la Plata contested the province; the peace settlement provided for an independent state.

Causes and outcome

Why was the Cisplatine War fought?

The Banda Oriental had been incorporated as Cisplatina under Portuguese rule in 1821 and remained under Brazil after its independence. A renewed uprising in 1825 challenged Brazilian control. The conflict became a war between Brazil and the United Provinces over the province’s future.

What was the outcome?

The Preliminary Peace Convention of 27 August 1828 provided for a free, independent state in Cisplatina and the withdrawal of both sides’ troops. Ratifications were exchanged in Montevideo on 4 October. The new state became Uruguay, rather than a province of either belligerent.
