National Union (in Spanish: Unión Nacional) was a political party in Peru.
It was originally called the Radical Party (Partido Radical) by one of its founders Manuel González Prada, though the name seemed too confrontational to many in the party and thus it became known as the National Union.
Support for the party was limited due to its basis on literature; many Peruvians were illiterate.
The party also called for greater European immigration to Peru.
Such a stance seems to be a paradox because many of its members defended Peru's Quechua speaking citizens.
