On March 8, 1917, the US Senate adopted the cloture rule to limit filibusters. Under Rule 22, two-thirds of Senators could vote to close debate on a given bill, thereby ending an ongoing filibuster. In 1975, that number was lowered to three-fifths of the Senate, which amounts to sixty Senators. Read a history of filibuster and cloture from the archives of the US Senate.

March 8 is International Women's Rights and International Peace Day, better known as International Women's Day.
