Preston Smith Brooks was an American slaveholder, politician and member of the U.S. House of Representatives from South Carolina, serving from 1853 until his resignation in July 1856 and again from August 1856 until his death.

Charles Sumner was an American lawyer, politician, and statesman who represented Massachusetts in the United States Senate from 1851 until his death in 1874. Before and during the American Civil War, he was a leading American advocate for the abolition of slavery. He chaired the Senate Foreign Relations Committee from 1861 to 1871, until he lost the position following a dispute with President Ulysses S. Grant over the attempted annexation of Santo Domingo. After breaking with Grant, he joined the Liberal Republican Party, spending his final two years in the Senate alienated from his party. Sumner had a controversial and divisive legacy for many years after his death, but in recent decades, his historical reputation has improved in recognition of his early support for racial equality.
