The Radical Republicans were a faction of American politicians within the Republican Party of the United States from around 1854 (before the American Civil War) until the end of Reconstruction in 1877. They called themselves "Radicals", with a goal of immediate, complete, permanent eradication of slavery, without compromise. They were opposed during the War by the moderate Republicans (led by U.S. President Abraham Lincoln), and by the pro-slavery and anti-Reconstruction Democratic Party as well as liberals in the Northern United States during Reconstruction. Radicals led efforts after the war to establish civil rights for former slaves and fully implement emancipation. After weaker measures in 1866 resulted in violence against former slaves in the rebel states, Radicals pushed the Fourteenth Amendment and statutory protections through Congress. They disfavored allowing ex-Confederate officers to retake political power in the Southern United States, and emphasized equality, civil rights and voting rights for the "freedmen", i.e. people who had been enslaved by state slavery laws within the United States.[1]

During the war, Radical Republicans opposed Lincoln's initial selection of General George B. McClellan for top command of the major eastern Army of the Potomac and Lincoln's efforts in 1864 to bring seceded Southern states back into the Union as quickly and easily as possible. Lincoln later recognized McClellan's weakness and relieved him of command. The Radicals passed their own Reconstruction plan through Congress in 1864, but Lincoln vetoed it and was putting his own policies in effect as military commander-in-chief when he was assassinated in April 1865.[2] Radicals pushed for the uncompensated abolition of slavery, while Lincoln wanted to pay slave owners who were loyal to the Union. After the war, the Radicals demanded civil rights for freed slaves, including measures ensuring suffrage. They initiated the various Reconstruction Acts as well as the Fourteenth Amendment and limited political and voting rights for ex-Confederate civil officials and military officers. They keenly fought Lincoln's successor, Andrew Johnson, a former slave owner from Tennessee who favored allowing Southern states to decide the rights and status of former slaves. After Johnson vetoed various congressional acts favoring civil rights for former slaves, they attempted to remove him from office through impeachment, which failed by one vote in 1868.
