Black suffrage in Pennsylvania

Prior to the early 1800s wealthy African-American men in Pennsylvania could vote just as their rich European-American male counterparts could. However, voting rights were expanded to include poor European-American men ("universal manhood suffrage"), in a shift that began the move away from a society stratified by wealth, to one which was now also based on race; black wealthy men were now no longer allowed to vote.
