What action did the Radical Republicans take during Reconstruction?

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" and were opposed during the War by the Moderate Republicans (led by President Abraham Lincoln), by the conservative Republicans, and the largely pro-slavery and later anti-Reconstruction Democratic Party, as well as by conservatives in the South and liberals in the North during Reconstruction.[1] Radicals strongly opposed slavery during the war and after the war distrusted ex-Confederates, demanding harsh policies for punishing the former rebels, and emphasizing equality, civil rights, and voting rights for the "freedmen" (recently freed slaves).[2]

During the war, Radical Republicans often opposed Lincoln in terms of selection of generals (especially his choice of DemocratGeorge B. McClellan for top command of the major eastern Army of the Potomac) and his efforts to bring seceded Southern states back into the Union as quickly and easily as possible. The Radicals passed their own reconstruction plan through the Congress in 1864, but Lincoln vetoed it and was putting his own presidential policies in effect by virtue as military commander-in-chief when he was assassinated in April 1865.[3] 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 freedmen, such as measures ensuring suffrage. They initiated the various Reconstruction Acts, and limited political and voting rights for ex-Confederate civil officials, military officers and soldiers. They bitterly fought President Andrew Johnson; they weakened his powers and attempted to remove him from office through impeachment, which failed by one vote in 1868.
