Which statement best summarizes the result of the withdrawal of federal protection during Reconstruction in South Carolina? Once federal protection was withdrawn, the Reconstruction Amendments were nullified in South Carolina. Without the presence of federal troops to offer protection, the Republican Party was able to take control of the state. After federal troops left South Carolina, old Confederate military units were reformed under different names. Over time, those who had governed South Carolina prior to the Civil War returned to power to control the state.

Explanation:

Following the withdrawal of federal troops from the southern states of the United States after the end of Reconstruction in 1877, the Democrats regained power in the south. Thus, violations of the rights of African Americans were reinstated, such as the literacy tests that prohibited them from voting, or the Jim Crow Laws that took away a large number of civil and political rights.

Furthermore, in the southern states, anti-African-American armed movements began to take shape, made up of former Confederate soldiers who, through violence, sought to subdue these people, with the aim of expelling them from these territories. These groups carried out their activities clandestinely, to avoid the control of the federal government, but they had the full support of the democratic state governments. Thus, groups such as the Klu Klux Klan or the Red Shirts began to carry out paramilitary and terrorist activities against African-Americans and, to a lesser extent, Republican voters.
