The city of Montevideo suffered a siege of eight years between 1843 and 1851, during which it was supplied by sea with British and French support. Oribe, with the support of the then conservative Governor of Buenos Aires Province Juan Manuel de Rosas, besieged the Colorados in Montevideo, where the latter were supported by the French Legion, the Italian Legion, the Basque Legion and battalions from Brazil. Finally, in 1851, with the additional support of Argentine rebels who opposed Rosas, the Colorados defeated Oribe. The fighting, however, resumed in 1855, when the Blancos came to power, which they maintained until 1865. Thereafter, the Colorado Party regained power, which they retained until past the middle of the 20th century.
