The term 'Stalwart Political Group' refers to a political faction within the Republican Party in the United States during the late 19th century. The group was led by Senator Roscoe Conkling of New York and was known for its strong support of President Ulysses S. Grant and his policies. The BASE of the Stalwart Political Group was the patronage system, which allowed the president to appoint people to government positions based on their loyalty to him rather than their qualifications.
