How were black codes and the 14th amendment related?

Black codes were laws enacted in the Southern states after the Civil War to restrict the rights and freedoms of newly freed African Americans. The 14th Amendment, ratified in 1868, aimed to provide citizenship and equal protection under the law to all persons born or naturalized in the United States, including former slaves. The existence of black codes highlighted the resistance to the 14th Amendment's principles, as they sought to undermine its intent by enforcing racial discrimination and limiting civil rights. Ultimately, the 14th Amendment was a response to such oppressive laws, seeking to establish a constitutional guarantee of equality.
