What was the purpose and effect of the 13th 14th and 15th amendments?

The 13th, 14th, and 15th Amendments to the U.S. Constitution were designed to secure civil rights for former slaves following the Civil War. The 13th Amendment abolished slavery, the 14th granted citizenship and equal protection under the law, and the 15th ensured voting rights regardless of race. Collectively, they aimed to promote equality and integrate African Americans into American society, though their effectiveness was often undermined by discriminatory practices and laws in subsequent years. These amendments laid the foundation for future civil rights advancements and ongoing struggles for racial equality.
