What did white Southerners do in response to the new freedoms of African Americans?

White Southerners, seeking to control the freedmen (former slaves), devised special state law codes. Many Northerners saw these codes as blatant attempts to restore slavery.

Explanation:

"White Southerners resented being ruled by Union military governors and Freedmen’s Bureau officials. They sought to restore self-rule. During the summer and fall of 1865, most of the old Confederate states held constitutional conventions. President Johnson’s reconstruction plan permitted only white persons to vote for convention delegates or to participate in the framing of the new state governments. Not surprisingly, none of the state conventions considered extending the right to vote to the freedmen. South Carolina’s provisional governor declared at his state constitutional convention that “this is a white man’s government.”" - (crf-usa.org)
