What are the 13th, 14th, and 15th Amendments to the Constitution?

The 13th-Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction. (It means that there are no slavery allowed anymore.)

The 14th-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. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. (It means that all men were created equally and nobody should treat others differently because of their own race, sex and religion.)

The 15th-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. (This means that they can't make the blacks or any other groups of people into slaves anymore because that is illegal nowadays.)
