What was one way that white supremacists gained back control in the south by the 1880's

Sharecropping

Explanation:

One of the ways in which white supremacists were able to regain control of the South, while excluding African Americans, was through the process of sharecropping. Sharecropping is a type of farming that involves families renting land in exchange for a portion of their crop, which is given to the landowner. Sharecropping became common in the South during Reconstruction, after the Civil War.

When slavery was abolished, the Southern economy was in chaos, and tensions arose between black farmers and white landowners. Through the process of sharecropping, penniless black farmers were able to farm. However, the unfair measures that surrounded this practice often meant that black people were trapped in a cycle of poverty and debt, leaving them powerless, and ensuring that white people remained in control of the region.
