The Reconstruction Amendments refer to the 13th, 14th, and 15th amendments to the United States Constitution, which were adopted between 1865 and 1870. These amendments aimed to secure rights and freedoms for formerly enslaved African Americans and were a significant part of the broader Reconstruction era following the Civil War. They collectively addressed issues such as abolishing slavery, granting citizenship and equal protection under the law, and ensuring voting rights, which represented a monumental shift in the political and social landscape for African Americans during this time.
