In 1964, The 24th Amendment prohibits poll taxes in federal elections.
The poll taxes in elections taxed every adult, without reference to their income or resources.
In this year, after years of people fighting to remove polls taxes, The Supreme Court finally rules that the use of poll taxes in state elections violates the equal protection clause of the 14th Amendment to the Constitution. And the last remaining poll taxes are eliminated.
This ruling, passed 47 years ago, protects all people from being taxed unfairly when they want to vote.
