Cause

The Uruguayan Civil War, fought between the Colorado and Blanco parties, escalated when Manuel Oribe, backed by Argentine caudillo Juan Manuel de Rosas, moved to assert control over Uruguay. His forces advanced on Montevideo in 1843, initiating a prolonged military investment of the capital.

Event

Beginning in 1843, Oribe's forces encircled Montevideo, creating a siege that lasted until 1851. The city, defended by the Gobierno de la Defensa under Joaquín Suárez, held out while Oribe's Gobierno del Cerrito controlled the surrounding countryside, effectively dividing Uruguay into two competing administrations.

Consequence

The siege resulted in nearly eight years of divided sovereignty in Uruguay. It ended in 1851 when Oribe capitulated following the intervention of Brazil and Entre Ríos against Rosas. The prolonged conflict drew international attention, including from France, and inspired Alexandre Dumas's 1850 work The New Troy.
