The Reconstruction Amendments, or the Civil War Amendments, are the Thirteenth, Fourteenth, and Fifteenth Amendments to the United States Constitution, adopted between 1865 and 1870. The amendments were a part of the implementation of the Reconstruction of the American South which occurred after the Civil War.

Explain in detail what each of the Reconstruction Amendments said and established.

1. Thirteenth Amendment (1865): The Thirteenth Amendment abolished slavery and involuntary servitude in the United States. It stated that "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." This amendment effectively ended the institution of slavery, which had been prevalent in the Southern states before and during the Civil War.

2. Fourteenth Amendment (1868): The Fourteenth Amendment granted citizenship to all persons born or naturalized in the United States, including former slaves. It also provided equal protection under the law for all citizens and prohibited states from denying any person life, liberty, or property without due process of law. Furthermore, it imposed penalties on states that denied the right to vote to male citizens over the age of 21. This amendment was intended to ensure the civil rights of all individuals and protect them from discrimination.

3. Fifteenth Amendment (1870): The Fifteenth Amendment prohibited the federal and state governments from denying a citizen the right to vote based on race, color, or previous condition of servitude. This amendment aimed to enfranchise African American men who had previously been excluded from voting in many Southern states. However, it did not guarantee the right to vote for women of any race. The Fifteenth Amendment was a significant step towards equality and civil rights for all citizens, regardless of race.

Overall, the Reconstruction Amendments were crucial in establishing the legal framework for civil rights and equality in the United States, particularly for African Americans who had been oppressed under slavery and faced discrimination after its abolition. These amendments were a key part of the Reconstruction era's efforts to rebuild and reform the South after the Civil War and ensure that all citizens were granted equal rights and protections under the law.
