Ratified in December 1865, the amendment formally ended the legal practice of slavery, which had long been a deeply entrenched institution in American society. This constitutional change marked a pivotal moment in American history, as it not only freed millions of enslaved individuals but also set the stage for subsequent civil rights advancements. The amendment’s passage was a key outcome of the Civil War and represented a fundamental shift in the nation’s legal and moral landscape, promoting the principle that all individuals should have the right to freedom.
