Answer:
14th amendment - Equal protection under the law irrespective of race,
Step-by-step explanation:
After its approval by the basic three-quarters of U.S. states, the 14th Amendment, gives citizenship to each and every person born or naturalized in the United States—it also consider former slaves—is officially signed into the U.S. Constitution.
In a two years period,when the Civil War came to an end, the Reconstruction Acts of 1867 grouped the South into five military districts, where new state governments, which stands on universal manhood suffrage, were to be formed. This gave birth to the period known as Radical Reconstruction, which brought into play the 14th Amendment, which had been passed by Congress in 1866, ratified in July 1868. The amendment dealt with pre-Civil War questions of African American citizenship by exerting on “all persons born or naturalized in the United States…are citizens of the United States and of the state in which they live in.” The amendment then confirmed with strong support on the privileges and rights of each and every citizen, and offered all these citizens the “equal protection of the laws.”
