Partido Republicano da Reconstituição Nacional
The Republican Party of National Reconstruction ( Portuguese : Partido Republicano da Reconstituição Nacional (PRRN) or simply Partido Reconstituinte ) was a political party in Portugal during the First Republic . The party took a liberal - conservative position and stood in opposition to the democrats who dominated during the first republic .
The PRRN emerged in the 1920s as a split from the Liberal Republican Party (PLR) . Its leading politician was Álvaro de Castro , who also led the only PRRN government (in 1920). Later the PRRN reunited with the PLR and the remnants of the old National Republican Party (the supporters of Sidónio Pais, who was murdered in 1918 ) to form the Republican Nationalist Party .
