What did the 14th and 15th amendments result in?

The 14th Amendment, ratified in 1868, granted citizenship to all persons born or naturalized in the United States and ensured equal protection under the law, significantly advancing civil rights for formerly enslaved people. The 15th Amendment, ratified in 1870, prohibited the federal and state governments from denying the right to vote based on race, color, or previous condition of servitude, aiming to secure political rights for African American men. Together, these amendments were foundational in the struggle for civil rights and laid the groundwork for future social justice movements in the United States.
