Background: Benjamin Ryan Tillman (August 11, 1847 - July 3, 1918) was a politician of the Democratic Party who served as Governor of South Carolina from 1890 to 1894, and a United States Senator from 1895 until his death in 1918. A white supremacist who opposed civil rights for blacks, Tillman led a paramilitary group of Red Shirts during South Carolina's violent 1876 election. On the floor of the U.S. Senate, he frequently ridiculed blacks, and boasted of having helped to kill them during that campaign. In the 1880s, Tillman, a wealthy landowner, became dissatisfied with the Democratic leadership and led a movement of white farmers calling for reform.
Context: Tillman was sworn in as governor in Columbia on December 4, 1890, before a crowd of jubilant supporters, the largest to see South Carolina's governor inaugurated since Hampton's swearing-in. In his inaugural address, Tillman celebrated his victory, "the citizens of this great commonwealth have for the first time in its history demanded and obtained for themselves the right to choose her Governor; and I, as the exponent and leader of the revolution which brought about the change, am here to take the solemn oath of office ... the triumph of democracy and white supremacy over mongrelism and anarchy, of civilization over barbarism, has been most complete."  Tillman made it clear he was not content that African Americans were allowed even a limited role in the political life of South Carolina:  The whites have absolute control of the State government, and we intend at any and all hazards to retain it. The intelligent exercise of the right of suffrage ... is as yet beyond the capacity of the vast majority of colored men. We deny, without regard to color, that "all men are created equal"; it is not true now, and was not true when Jefferson wrote it.  The legislature, at Tillman's recommendation, reapportioned itself, costing Charleston County four of its twelve seats, and other lowcountry counties one each, with the seats going to the upcountry. Although Tillman sought to reduce public expenditures, he was not successful in doing so as his reform program required spending, and the legislature could find few savings to make. Construction of Clemson College was slowed, and subsidies for fairs were cut.  Among the matters before the new, Tillman-controlled legislature was who should fill the Senate seat held by Hampton, whose term expired in March 1891--until 1913, state legislatures elected senators. There was a call from many in the South Carolina Democratic Party to re-elect Hampton, who had played a major role in the state for the past thirty years, in war and peace. Tillman was embittered against Hampton for a number of slights, including the senator's neutrality in the race against Haskell. The legislature retired Hampton, who received only 43 of 157 votes, and sent Irby to Washington in his place. The ouster of Hampton was controversial, and remained so for decades afterwards; according to Simkins (writing in 1944), "to future generations of South Carolinians, Tillman's act was a ruthless violation of cherished traditions of which Hampton was a living symbol".
