(1870) African-American men get the voteFollowing a difficult ratification, the US Constitution’s 15th Amendment is adopted, formally granting all adult black men, regardless of “previous condition of servitude,” the right to vote. By the late 1870s, Southern states will nevertheless take various steps to disenfranchise black voters. It will take another 50 years for American women, of any race, to win the right to vote.The Fifteenth Amendment to the United States Constitution prohibits the federal and state governments from denying a citizen the right to vote based on that citizen’s “race, color, or previous condition of servitude”. It was ratified on February 3, 1870, as the third and last of the Reconstruction Amendments.
