Which amendment ensure that the newly freed slaves in the South retreated somewhat humble a between 1867 in 1876?

The 14th Amendment, ratified in 1868, played a crucial role in ensuring that newly freed slaves in the South were granted citizenship and equal protection under the law. However, despite its intentions, the period between 1867 and 1876 saw the implementation of discriminatory laws and practices, such as Black Codes and Jim Crow laws, which sought to suppress the rights and freedoms of African Americans. While the 14th Amendment provided a legal framework for equality, systemic racism and resistance in the South limited its effectiveness during this time.
