The Battle of Caseros (Spanish: Batalla de Caseros; Portuguese: Batalha de Caseros) was fought near the town of El Palomar, Argentina, on 3 February 1852, between forces of the Argentine Confederation, commanded by Juan Manuel de Rosas, and a coalition consisting of the Argentine provinces of Entre Ríos and Corrientes, the Empire of Brazil, and Uruguay. The allied forces, known as the Grand Army (Ejército Grande), defeated Rosas, who fled to the United Kingdom. This defeat marked a sharp division in the history of Argentina. After the battle, Justo José de Urquiza, a caudillo and governor of Entre Ríos, became the provisional Director of the Argentine Confederation and sponsored the creation of the country's constitution in 1853, later becoming the first constitutional president of Argentina in 1854.
