Which amendment in the U.S. Constitution discusses the right to vote?

The Nineteenth Amendment specifically addresses the right to vote by granting women the legal right to participate in elections. Ratified in 1920, it states, "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex." This amendment was a pivotal moment in the women's suffrage movement, as it legally recognized and protected women's voting rights at a federal level, contributing significantly to the broader struggle for civil rights in the U.S.

The First Amendment focuses primarily on freedoms such as speech, religion, press, assembly, and petition, without explicitly mentioning the right to vote. The Thirteenth Amendment abolishes slavery and involuntary servitude but does not directly pertain to voting rights. The Twenty-second Amendment, on the other hand, limits the number of terms a president can serve, which is unrelated to voting rights itself. Thus, the Nineteenth Amendment stands out as the one that directly relates to the expansion of voting rights in the United States.
