Which amendment abolished slavery in the United States?

The 13th Amendment to the United States Constitution is significant because it formally abolished slavery and involuntary servitude across the nation. Ratified in 1865, this amendment marked a pivotal moment in American history, as it not only sought to end the practice of slavery but also aimed to strengthen the foundation of civil rights in the post-Civil War era. By legally eliminating the institution of slavery, the 13th Amendment represented a crucial step towards equality and civil liberties for all individuals, particularly for African Americans who had been subjected to oppressive conditions under slavery.

In contrast, the 14th Amendment, ratified in 1868, addressed citizenship rights and equal protection under the law, while the 15th Amendment, ratified in 1870, focused on protecting the voting rights of men regardless of race, color, or previous condition of servitude. The 19th Amendment, ratified in 1920, granted women the right to vote. Each of these amendments plays a critical role in expanding civil rights and liberties in the United States, but only the 13th Amendment specifically addresses the abolition of slavery.
