In a death knell to Jim Crow laws, the Supreme Court on June 21, 1915, struck down an Annapolis grandfather lause that largely prevented African-Americans from participating in municipal elections.
That week, the Supreme Court ruled on two related cases involving the city of Annapolis and the state of Oklahoma. Both had cases against them that challenged the constitutionality of certain voting requirements.
At stake in Annapolis was a grandfather clause that said that any person whose grandfather was not a registered voter in the state was not eligible to register to vote.
The Sun's front page headlines reporting the decision read: "Decree Opens Door to Negro.....Eliminates Color Line in All Municipal Elections....Heavy Blow to South."
The case began when three African-American men sued registration officials of Annapolis' Third Ward because they were not allowed to register to vote in a city election held on July 12, 1909.
