National Party of Uruguay
The National Party (Spanish: Partido Nacional, PN), widely known as the White Party (Partido Blanco), is one of the most influential and historic political organizations in Uruguay. Established during the nation's formative years as an independent state, the party has played a central role in shaping the country's governance, representing a blend of nationalist, liberal, and humanist values.
Founded in 1836 by General Manuel Oribe, the National Party has spent much of its history as a counterbalance to the Colorado Party. While it has a long tradition of serving in the political opposition, it continues to be a dominant force in Uruguayan politics, particularly among rural populations and those advocating for the decentralization of power.

Key Facts
- Founded: August 10, 1836, by Manuel Oribe.
- Political Position: Centre-right.
- Core Ideologies: Liberal conservatism, Christian democracy, and nationalism.
- Current Leader: Luis Lacalle Pou.
- Slogan: "La unión nos hará fuerza" (Unity makes strength).
- Primary Base: Strong support in rural areas and the interior of the country.
Historical Foundations
The party's identity was forged during the Uruguayan Civil War. On August 10, 1836, Manuel Oribe decreed the use of a white banner inscribed with "Defenders of the Laws." This distinction became permanent after the Battle of Carpintería, where white badges were used to differentiate Oribe's forces from the revolutionary army of Fructuoso Rivera, leading to the party's enduring nickname, the "White Party."
In 1872, the party adopted its first Program of Principles. This foundational document emphasized the maintenance of peace, the protection of minority representation, the promotion of education, and the strengthening of justice and decentralization.
Evolution of Leadership
While Manuel Oribe is the official founder, Aparicio Saravia is revered as the party's primary historical caudillo (a charismatic military or political leader) and its chief idealist. In recent history, the party saw a significant milestone in March 2020 when Luis Lacalle Pou was sworn in as President, marking the return of a conservative government after 15 years of leadership by the left-wing Broad Front coalition.
Ideology and Internal Factions
The National Party is a broad tent on the centre-right, encompassing various tendencies from liberal to conservative. It describes itself as Pan-Americanist and humanist, though it often experiences internal debate regarding social issues such as same-sex marriage, euthanasia, and the legalization of abortion. Notably, the party's youth wing, Juventud Partido Nacional, has trended toward more favorable positions on LGBT rights.
The party is divided into three primary ideological factions:
- Herrerism: The most influential wing, characterized by economic liberalism and conservatism. It originated with Luis Alberto de Herrera and has been led by a family line including former president Luis Alberto Lacalle and current president Luis Lacalle Pou.
- National Alliance: A centrist faction rooted in Christian democracy.
- Wilsonist Current: A social-liberal faction.
Electoral Performance and Governance
Historically, the National Party has been the champion of the "interior," opposing the centralist policies of the capital, Montevideo. This has secured them a loyal demographic base in rural regions.
The party's electoral history is marked by the Ley de Lemas system (used from 1942 to 1994), which allowed multiple presidential candidates per party. Under this system, the total votes for all candidates in a party were combined to determine the winning party, and the top individual candidate from that party became president. A 1996 referendum ended this practice, restricting parties to a single presidential candidate starting in 1999.
The party's current legislative and administrative strength is reflected in its representation across the Chamber of Deputies, the Senate, and various local governments (Intendencias and Mayoralties).
