A significant outcome of the Civil War Amendments in American history was the constitutional guarantee of citizenship and equal protection under the law for former enslaved people. The 13th Amendment abolished slavery, while the 14th Amendment granted citizenship to all persons born or naturalized in the United States, including former enslaved individuals. Furthermore, the 15th Amendment aimed to secure voting rights regardless of race. Collectively, these amendments were pivotal in reshaping American society, contributing to the ongoing struggle for civil rights and equality, and setting the groundwork for future social justice movements.
