Please help me with this one question for history!

During Reconstruction, three amendments to the Constitution were made in an effort to establish equality for black Americans. The Thirteenth Amendment, adopted in 1865, abolishes slavery or involuntary servitude except in punishment for a crime. During the decade known as Radical Reconstruction (1867-77), Congress granted African American men the status and rights of citizenship, including the right to vote, as guaranteed by the 14th and 15th Amendments to the U.S. Constitution. The 14th Amendment to the U.S. Constitution, ratified in 1868, granted citizenship to all persons born or naturalized in the United States—including former slaves—and guaranteed all citizens “equal protection of the laws.”The 15th Amendment to the U.S. Constitution granted African American men the right to vote by declaring that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude.
