Battle of Las Piedras

Uruguay · Date: Monday, May 18, 2026

A national holiday in Uruguay commemorating the 1811 victory of revolutionary forces against Spanish colonial troops, a key step toward independence.

Origin & history

The Battle of Las Piedras was fought on May 18, 1811, between the revolutionary forces led by José Gervasio Artigas and the Spanish royalist army commanded by General José Posadas. The encounter took place near Las Piedras, a town in the Canelones Department. Artigas, who would later become the national hero of Uruguay, orchestrated a strategic victory that significantly boosted the morale of the independence movement. The battle marked the first major success of the Uruguayan Revolution against Spanish rule. Artigas's forces, composed mainly of local gauchos and indigenous people, used guerrilla tactics to overcome the better-equipped Spanish troops. This victory paved the way for the eventual independence of Uruguay, which was formally achieved in 1828. The event is remembered as a turning point that inspired further revolts across the region and cemented Artigas's role as the father of Uruguayan nationhood.

Customs & traditions

The day is marked with official ceremonies, including a wreath-laying at the monument of José Artigas in Montevideo's Plaza Independencia. Military parades and reenactments of the battle are held in Las Piedras, where actors in period uniforms demonstrate the combat tactics used in 1811. Schools and public institutions organize educational events about the battle and Artigas's legacy. Many Uruguayans spend the day with family, attending local fairs or enjoying asado (barbecue). Traditional Uruguayan foods like chivito (steak sandwich), choripán (grilled sausage in bread), and dulce de leche desserts are popular. Some communities host folk music and dance performances, celebrating the gaucho culture that played a key role in the revolution. Although it is a public holiday, many businesses remain open in tourist areas, and the overall atmosphere is patriotic but relaxed.

Why it is celebrated

The Battle of Las Piedras is celebrated as a foundational moment in Uruguay's struggle for independence. It represents the courage and determination of the Uruguayan people to free themselves from Spanish colonial rule. For modern Uruguayans, the holiday honors the ideals of freedom, sovereignty, and national identity embodied by Artigas. It serves as a reminder of the sacrifices made by past generations and reinforces a sense of unity and pride in the country's history.
