How did democrats regain control of southern governments from the Republican Party

Post civil war

The Democrats used the racist backlash against the freeing of the slaves as a tool to regain power. They generally opposed Republican policies of reintegration and policies encouraged at moving the country forward after the Civil War.

Answer: They had to regain political power.

Explanation:

During the Reconstruction years, the Democratic Party worked to recover political power in the South appealing to the white Southerners who resisted the Republican ideas about civil and voting rights of African Americans. They spread ideas of white racism and practiced election fraud to gradually return to power in the Southern states throughout the 1870s.
