Question

When did Black Women get their right to vote?

Answer 1

African-Americans got the right to vote before women did, so legally, Black Women got the right to vote when all women did - in 1920. So before 1920 no women, black or white could vote - therefore pictures from 1920s likely portray women that recently got the right to vote.

In practice, Black women were harassed and denied the right to vote until 1960s, but this has nothing to do with the law (they were entitled to vote in 1920) but with the racism of the officers and administration workers.
