Answer:
The Republican Party struggled in the South because most Southerners resented Reconstruction.
Explanation:
Reconstruction was a period after the end of the Civil War in which the Republican federal government tried to transform Southern states from slave economies to states where the former slaves were now free citizens with civil rights. In this context, radical Republicans wanted to enact laws, institutions and governing powers that guaranteed such rights for all Americans, while Presidents Abraham Lincoln and Andrew Johnson leaned toward a more moderate line to try to stabilize the Union as quickly as possible.
During this time, three amendments were made to the Constitution, known as Reconstruction Amendments. These abolished slavery and forced labor, gave equal protection to the law, and prohibited discrimination on grounds of race, color, or past slave condition. Congress also passed the first Civil Rights Act, the Civil Rights Act of 1875, which banned discrimination in public transportation, public places and in juries. But after about a decade of rapid change, conservative Democratic forces struck back many of them, and the Reconstruction period ended in 1877, when the last federal troops were withdrawn from the Southern states. This was due to the lack of support from the southern Democrat citizens to the Republican Party, which was the sector that promoted the Reconstruction process.
