Answer
The Stalwart faction of the Republican Party, led by Roscoe Conkling, represented a conservative wing of the party that opposed civil service reform and sought to preserve the patronage system. They clashed with the Half-Breed faction, led by James G. Blaine, which supported Pendleton's Civil Service Reform Act of 1883. The Stalwarts lost influence after Conkling's defeat in the 1884 presidential election, and the Half-Breeds gained dominance within the party.
