The Republican Union Party (Portuguese: Partido da União Republicana, PUR), commonly known as the Republican Union or the Unionist Party, was a political party in Portugal.
The party was established on 24 February 1912 as the result of a split in the National Republican Union (UNR), with one faction breaking away to form the Evolutionist Party and the rump of the UNR becoming the Republican Union.[1] [2] It won 15 seats in the House of Representatives and 11 seats in the Senate in the 1915 parliamentary elections, emerging as the third-largest faction after the Democratic Party.
The party boycotted the 1918 elections,[3] but returned to run in the 1919 elections, in which it won 17 House seats, regaining its place as the third-largest party.
In 1919 the party merged with the Evolutionist Party to form the Republican Liberal Party.[1]
