Factions in the Republican Party (United States)
The Republican Party in the United States includes several factions, or wings. During the 19th century, Republican factions included the Half-Breeds, who supported civil service reform; the Radical Republicans, who advocated the immediate and total abolition of slavery, and later advocated civil rights for freedmen during the Reconstruction era; and the Stalwarts, who supported machine politics.
