Final answer:
The Fourteenth Amendment granted citizenship to African-Americans and anyone born in the United States, providing equal protection under state and federal law.
Step-by-step explanation:
The Fourteenth Amendment, ratified in 1868, granted citizenship to African-Americans and anyone born in the United States. It stated that 'All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.' This amendment also provided equal protection under both state and federal law, overturning the Dred Scott decision. It played a significant role in ensuring civil rights for African-Americans and establishing their citizenship rights.
