The Great Siege of Montevideo (Spanish: Gran Sitio de Montevideo), named as Sitio Grande in Uruguayan historiography, was the siege suffered by the city of Montevideo between 1843 and 1851 during the Uruguayan Civil War.
In practice, this siege meant that Uruguay had two parallel governments:
Gobierno de la Defensa in Montevideo, led by Joaquín Suárez (1843 – 1852)
Gobierno del Cerrito (with headquarters in the present-day neighborhood of Cerrito de la Victoria), ruling the rest of the country, led by Manuel Oribe (1843 – 1851)
The siege inspired a book by the French writer Alexandre Dumas, The New Troy (1850).
