词源
From late 19th-century legislation and constitutional amendments passed by a number of U.S. Southern states, which created new literacy and property restrictions on voting, but exempted those whose grandfathers had the right to vote before the American Civil War. The intent and effect of such rules was to prevent poor and illiterate African American former slaves and their descendants from voting, but without denying poor and illiterate whites the right to vote.
