Why did the "Civil War Amendments" (13th, 14th, and 15th) of the United States Constitution have limited effects on the status of African Americans in the South during the decades following the Civil War?

A) The Civil Rights Amendments only applied to states of the Union, so states of the old Confederacy ignored them.
B) Southern states used “Black Codes” and other legal and traditional measures to keep African Americans’ rights limited.
C) The Confederate states never agreed to the terms of the peace of the war, so all restrictions on African Americans remained intact.
D) The Civil Rights Amendments had little to do with the rights of African Americans, but rather the amendments focuses on the rights of women and children.
Answer: Southern states used “Black Codes” and other legal and traditional measures to keep African Americans’ rights limited.
