What was one key outcome of the 13th Amendment?

The 13th Amendment, ratified in 1865, is a pivotal piece of legislation in American history that abolished slavery throughout the United States. This amendment formally ended the legal practice of slavery, ensuring that neither slavery nor involuntary servitude, except as punishment for a crime, could exist within the borders of the nation. By enshrining this principle into the Constitution, the 13th Amendment marked a significant turning point in the country’s legal and social landscape, directly influencing the course of civil rights and equality in the years to follow.

It's important to recognize that the other options reflect key developments in American civil rights but do not pertain to the direct implications of the 13th Amendment. The right to vote for women was established later with the 19th Amendment, citizenship for all born in the U.S. was reinforced by the 14th Amendment, and race-based voter discrimination was addressed by the Voting Rights Act of 1965. Understanding the specific impact of the 13th Amendment helps highlight its historic role in shaping American society and law.
