The civil rights movement (also known as the American civil rights movement and other terms) in the United States was a decades-long struggle with the goal of enforcing constitutional and legal rights for African Americans that other Americans already enjoyed.
After the American Civil War and the abolition of slavery in the 1860s, the Reconstruction Amendments to the United States Constitution granted emancipation and constitutional rights of citizenship to all African Americans, most of whom had recently been enslaved.
