The 17, 19, 23, 24, and 26 amendments have expanded voting rights.
The 13th Amendment to the U.S. constitution abolished slavery and the 14th made African-Americans U.S. citizens. With the 15th Amendment, voting rights could not be denied on account of race, color, or previous condition of servitude.. In theory, all African-American men now had the right to vote.he 19th Amendment gave voting rights to women, including African-American women, in 1920. In 1964, the 24th Amendment outlawed poll taxes, removing another major barrier to African-American voting. In 1965, President Lyndon Johnson signed the Voting Rights Act into law.
