Explanation:

The Thirteenth Amendment to the U.S. Constitution abolished slavery and involuntary servitude, except as punishment for a crime. It did not address Black Codes, school - segregation, or voting rights for African Americans. The Black Codes were state laws that restricted the rights of African Americans after the Civil War. School segregation was addressed by the Brown v. Board of Education case in 1954, and African - American voting rights were addressed by the Fifteenth Amendment.

Answer:

slavery became illegal across the United States.
