Source-derived summary

The Treinta y Tres Orientales (English: Thirty-Three Orientals or Thirty-Three Easterners) were a revolutionary group led by Juan Antonio Lavalleja and Manuel Oribe that started an insurrection against the Empire of Brazil during the Brazilian occupation of the Provincia Oriental. Their actions started in with the crossing of the Uruguay River on the night of April 19, 1825, an event that marked the beginning of the Cisplatine War, and culminated in the foundation of modern Uruguay.

Background

Between 1816 and 1820, the United Kingdom of Portugal, Brazil and the Algarves invaded and occupied the post-Spanish Provincia Oriental. These Luso-Brazilian forces easily defeated the resistance of the forces of José Gervasio Artigas who, when routed, had to abandon the province in 1820, and went into self-exile in Paraguay.

In February 1824 Oriental Province was annexed under the name Cisplatina Province by newly independent Brazil. It had held the same name under the former Portuguese colonial administration. Previously, a separatist movement (1822–1823) directed by various partisans of the United Provinces of the Río de la Plata (present day Argentina) had been subdued by the Brazilians. The goal of the doomed movement had been the unification of Cisplatina with the United Provinces.

Organization

One of the military leaders of the partisans, Lavalleja, who had fought together with Artigas against the Portuguese and Brazilians, organized a new military expedition, from Buenos Aires Province to Cisplatina Province. The goal was again to expel the Brazilians and unite Cisplatina Province with the United Provinces of the Río de la Plata.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Thirty-Three Orientals”, the useful work is to connect “militant revolutionary group” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q942460. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1825, 1816, 1820 and 1824.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
