Thirty-Three Orientals were a band of thirty-three armed men led by Juan Antonio Lavalleja who launched an 1825 expedition from Buenos Aires to the Banda Oriental to spark a rebellion against Brazilian Empire control. The group’s crossing and landing precipitated the Cisplatine War between the United Provinces of the River Plate and the Brazilian Empire and paved the way for the creation of the independent state of Uruguay. Their action became a foundational episode in Uruguayan history and a symbol invoked by political factions such as Partido Colorado and Partido Nacional.

Background and Origins

The expedition emerged amid geopolitical tensions involving the United Provinces of the River Plate, the Brazilian Empire, and local caudillos after the Congress of Vienna-era rearrangements and the collapse of Spanish Empire authority in South America. The Banda Oriental had been contested since the Luso-Brazilian invasion of 1816 and the subsequent annexation as the Cisplatina Province by Prince Regent João-led United Kingdom of Portugal, Brazil and the Algarves. Regional leaders including José Gervasio Artigas and later Fructuoso Rivera had earlier resisted foreign influence; by 1825 exile communities in Buenos Aires and political émigrés such as Andrés Lamas and Bernardino Rivadavia debated forms of reincorporation and independence. The conspirators coordinated with dignitaries from Montevideo and the Oriental exiles in Buenos Aires to exploit Brazil’s preoccupation with internal rebellions and Portuguese legacies.

Organization and Members

The unit’s nominal leader was Juan Antonio Lavalleja, a veteran of earlier campaigns under figures like José Artigas and allied in various phases with Manuel Oribe and Fructuoso Rivera. The thirty-three included landowners, clerics, military veterans and émigrés drawn from provinces such as Canelones, Soriano, Colonia del Sacramento and Paysandú. Prominent individuals among them included Luis de la Cruz, Gervasio Antonio de Posadas-era officers, and local notables like Santiago Vázquez; some members later became legislators in the Assembly of the Oriental Province. The contingent coordinated with political operatives in Buenos Aires including envoys to Manuel Dorrego and contacts within the Portena political networks. Financing and materiel were secured through private patrons, merchant allies in Montevideo and sympathetic military figures such as Carlos María de Alvear-aligned officers.

The 1825 Expedition and Campaign

The crossing from Buenos Aires to the Banda Oriental occurred in April 1825, with the force landing near La Florida and initiating the proclamation known as the "Pronunciamiento de los Treinta y Tres" that called for liberation from Brazilian authority and reunion with the United Provinces. The insurgents linked up with uprisings in Cerro Largo and Maldonado and fought skirmishes culminating in engagements associated with the larger Cisplatine War. Key clashes within the campaign context included the Battle of Sarandí and guerrilla-style actions that disrupted Brazilian Imperial Army control in the countryside. The successful mobilization led to the Assembly of Florida which ultimately declared the secession of the Banda Oriental from the Brazilian Empire and endorsed accession talks with the United Provinces of the River Plate.

Political and Military Impact

The expedition’s immediate political effect was to precipitate formal war between the United Provinces of the River Plate and the Brazilian Empire (the Cisplatine War), drawing in naval commanders like William Brown and land commanders such as José María Paz. International diplomacy involved actors like Great Britain and figures tied to the Congress of Aix-la-Chapelle-era balance; British mediation helped lead to the 1828 Preliminary Peace Convention and the negotiated creation of an independent buffer state, the Estado Oriental del Uruguay. The campaign reshaped regional alignments among caudillos including Manuel Oribe and Fructuoso Rivera, influenced partisan development of the Partido Colorado and Partido Blanco, and affected later conflicts like the Guerra Grande by embedding Lavalleja-era legitimacy claims in Reynaldo narratives and constitutions.

Legacy and Cultural Representation

The thirty-three became enduring symbols in Uruguayan national mythology, commemorated in monuments such as the Obelisco de Montevideo and celebrations like the national holiday marking the "Landing of the Thirty-Three." Their image appears in visual arts by painters referencing the independence era, in historiography authored by Eduardo Acevedo, José Pedro Varela scholarship, and in literature touching on postcolonial identity debates. Political movements from Partido Colorado to Blanco factions have invoked their memory in campaigns, while composers and playwrights staged works in venues like the Solís Theatre. Museums such as the Museo Nacional de Artes Visuales and collections in Montevideo preserve related artifacts and iconography, and the episode is cited in constitutional histories and school curricula across Uruguay and the Río de la Plata region.
