Jonas Halstead Coe, sometimes given in Spanish as Comodoro Juan Coe, was an American-born naval commander, notable in the early naval history of Argentina and Uruguay.

The Cry of Asencio or Admirable alarm was an 1811 pronunciamiento that took place at the Banda Oriental against the Spanish rule in Montevideo. Made in support of Buenos Aires, which had already ousted the viceroy and established a local government during the May Revolution, it is considered the beginning of the Oriental revolution.

The Battle of Montevideo was a battle between the British and Spanish Empires during the Napoleonic Wars, in which British forces captured the city of Montevideo. It formed part of the British invasions of the River Plate. Locally, it is remembered as the Siege of Montevideo.

The Portuguese invasion of the Banda Oriental was a short-lived and failed attempt, beginning in 1811 and ending the following year, by the Portuguese Empire to annex the remaining territory of the Spanish Viceroyalty of the Río de la Plata.

The Portuguese conquest of the Banda Oriental was the armed-conflict that took place between 1816 and 1820 in the Banda Oriental, for control of what today comprises the whole of the Republic of Uruguay, the northern part of the Argentine Mesopotamia and southern Brazil. The four-year armed-conflict resulted in the annexation of the Banda Oriental into the United Kingdom of Portugal, Brazil and the Algarves as the Brazilian province of Cisplatina.

The Siege of Paysandú began 3 December 1864, during the Uruguayan War, when Brazilian forces and Colorado forces attempted to capture the city of Paysandú in Uruguay from its Uruguayan Army defenders. The siege ended 2 January 1865, when the Brazilian and Colorado forces conquered the town.

The Spanish-Portuguese War between 1735-1737 was fought over the Banda Oriental, roughly present-day Uruguay.
