Colorado Party (Uruguay) in the context of Broad Front (Uruguay)

The Redshirts (Italian: Camicie rosse or Giubbe rosse), also called the Red Coats, are volunteers who followed the Italian patriot Giuseppe Garibaldi during his campaigns. The name derived from the colour of their shirts or loose-fitting blouses that the volunteers, usually called Garibaldini, wore in lieu of a uniform.

The force originated as the Italian Legion supporting the Colorado Party during the Uruguayan Civil War. The story is that Garibaldi was given red shirts destined for slaughterhouse workers. Later, during the wars of Italian unification, the Redshirts won several battles against the armies of the Austrian Empire, the Kingdom of Two Sicilies and the Papal States. Most notably, Garibaldi led his Redshirts in the Expedition of the Thousand of 1860, which concluded with the annexation of Sicily, Southern Italy, Marche, and Umbria to the Kingdom of Sardinia, which led to the creation of a unified Kingdom of Italy. His military enterprises in South America and Europe made Garibaldi become known as the "Hero of the Two Worlds".

The Uruguayan Civil War, also known in Spanish as the Guerra Grande ("Great War"), was a series of armed conflicts between the leaders of Uruguayan independence. While officially the war lasted from 1839 until 1851, it was a part of armed conflicts that started in 1832 and continued until the final military defeat of the Blancos faction in 1904.

Supporters of the two opposing presidents Rivera and Oribe formed two political parties: the Colorado Party and the National Party, both of which received backing and support from foreign sources, including neighboring Empire of Brazil, the Argentine Confederation, Buenos Aires Province as well as European powers, primarily the British Empire and the Kingdom of France, but also a legion of Italian volunteers including Giuseppe Garibaldi. The great diversity of nationalities among the military forces supporting the Colorado Party posed difficulties in arguing for their struggle in terms of a "national liberation"; instead, the Colorado Party side argued that they were defending "humanity" and "civilization" against "tyranny".

José Fructuoso Rivera y Toscana (17 October 1784 – 13 January 1854) was a Uruguayan general and patriot who fought for the liberation of Banda Oriental from Brazilian rule, thrice served as President of Uruguay and was one of the instigators of the long Uruguayan Civil War. He is also considered to be the founder of the Colorado Party, which ruled Uruguay without interruption from 1865 until 1958. He made a controversial decision to almost completely eliminate the native Charrúa during the 1831 Massacre of Salsipuedes.

Manuel Ceferino Oribe y Viana (August 26, 1792 – November 12, 1857) was the 2nd Constitutional president of Uruguay and founder of Uruguay's National Party, the oldest Uruguayan political party and considered one of the two Uruguayan "traditional" parties, along with the Colorado Party, which was, until the 20th century, its only political adversary.

The National Party (Spanish: Partido Nacional, PN) also known as the White Party (Spanish: Partido Blanco), is a major political party in Uruguay. Founded in 1836 by General Manuel Oribe, it is one of the country's oldest active political parties along with the Colorado Party, their origin dates back to the establishment of Uruguay as an independent state.

Positioned on the centre-right of the political spectrum, the National Party is ideologically liberal, nationalist, Pan-Americanist and humanist. Considering the interim co-government of the Gobierno del Cerrito headed by Manuel Oribe, and the Defense Government from Montevideo led by the Colorado Joaquín Suarez, in the middle of the Uruguayan Civil War, and with the exception of the administration of Luis Lacalle Pou, the PN has ruled the country for 35 years interruptedly throughout its history. The party has a long tradition of being in the political opposition during the 19th and 20th centuries, against its traditional adversary, the Colorado Party. Although Manuel Oribe is recognized as the party's founder, Aparicio Saravia is considered its idealist and main historical caudillo.

The Uruguayan War (10 August 1864 – 20 February 1865) was fought between Uruguay's governing Blanco Party and an alliance consisting of the Empire of Brazil and the Uruguayan Colorado Party, covertly supported by Argentina. Since its independence, Uruguay had been ravaged by intermittent struggles between the Colorado and Blanco factions, each attempting to seize and maintain power in turn. The Colorado leader Venancio Flores launched the Liberating Crusade in 1863, an insurrection aimed at toppling Bernardo Berro, who presided over a Colorado–Blanco coalition (fusionist) government. Flores was aided by Argentina, whose president Bartolomé Mitre provided him with supplies, Argentine volunteers and river transport for troops.

The fusionism movement collapsed as the Colorados abandoned the coalition to join Flores' ranks. The Uruguayan Civil War quickly escalated, developing into a crisis of international scope that destabilized the entire region. Even before the Colorado rebellion, the Blancos within fusionism had sought an alliance with Paraguayan dictator Francisco Solano López. Berro's now purely Blanco government also received support from Argentine federalists, who opposed Mitre and his Unitarians. The situation deteriorated as the Empire of Brazil was drawn into the conflict. Almost one fifth of the Uruguayan population were considered Brazilian. Some joined Flores' rebellion, spurred by discontent with Blanco government policies that they regarded as harmful to their interests. Brazil eventually decided to intervene in the Uruguayan affair to reestablish the security of its southern frontiers and its regional ascendancy.

General elections were held in Uruguay on 31 October 2004, alongside a constitutional referendum. The result was a victory for the Broad Front, marking the first time a party other than the Colorado Party or National Party had held power since the two parties were formed in the 1830s.

Broad Front leader Tabaré Vázquez was elected president on his third attempt after his party won just over 50% of the vote, enough for him to win the presidency in a single round. To date, this is the only time that a presidential election has been decided without a runoff since the two-round system was introduced in 1999. The Broad Front also won majorities in the Chamber of Deputies and the Senate.

General elections were held in Uruguay on 25 October 2009 alongside a two-part referendum. As no candidate for president received more than 50% of the vote, a second round was held on 29 November between the top two candidates, José Mujica of the ruling Broad Front (who received 48% of the vote) and former president Luis Alberto Lacalle of the National Party (29%). Mujica won the run-off with 55% of the vote.

In the parliamentary elections, the Broad Front retained its majorities in both chambers, winning 16 of the 30 seats in the senators and 50 of the 99 seats in the Chamber of Deputies. The National Party finished second with 9 senators and 30 deputies, the Colorado Party third with 5 Senators and 17 Deputies, and the Independent Party fourth with 2 deputies.
