Which amendment abolished slavery in the United States?

The 13th Amendment is significant because it formally abolished slavery and involuntary servitude in the United States, except as punishment for a crime. Ratified on December 6, 1865, this amendment marked a pivotal point in American history, eradicating a practice that had been a deeply entrenched institution. By doing so, it aimed to guarantee freedom for all individuals, ensuring that no person could be held in bondage against their will.

The other amendments mentioned do not pertain to the abolition of slavery. The 1st Amendment protects freedoms concerning religion, expression, assembly, and the right to petition. The 15th Amendment, ratified in 1870, prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude," while 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, but it was specifically the 13th Amendment that ended the institution of slavery in the United States.
