The statement that accurately describes the effects of the Thirteenth, Fourteenth, and Fifteenth amendments on the lives of southerners is:
Black southerners had more political and economic freedom.
The Thirteenth Amendment abolished slavery, the Fourteenth Amendment granted citizenship and equal protection under the law, and the Fifteenth Amendment granted the right to vote regardless of race. While these amendments were significant in providing rights to Black southerners, it is important to note that there was substantial resistance and many obstacles to the full realization of these rights in the South, including Jim Crow laws and other forms of discrimination.
