How did the 13th 14th and 15th amendment affect the US?

The 13th, 14th, and 15th Amendments, collectively known as the Reconstruction Amendments, profoundly transformed the United States by abolishing slavery, granting citizenship and equal protection under the law, and securing voting rights for African American men. The 13th Amendment, ratified in 1865, abolished slavery, while the 14th Amendment, ratified in 1868, established birthright citizenship and aimed to provide equal protection to all citizens. The 15th Amendment, ratified in 1870, prohibited denying the right to vote based on race or color. Together, these amendments laid the groundwork for civil rights advancements and significantly shaped the legal and social landscape of the nation.
