A member of a faction of the Republican Party toward the end of the nineteenth century. Stalwarts were the "traditional" Republicans who opposed Rutherford B. Hayes's civil service reform. They were pitted against the Half-Breeds (moderates) for control of the Republican Party. The only real issue between Stalwarts and Half-Breeds was patronage. The Half-Breeds worked to get civil service reform, and finally created the Pendleton Civil Service Reform Act. Stalwarts favored traditional machine politics.
