It wasn’t until 1920 that women were granted suffrage, but it was 1917 when members of the National Women’s Party —Alice Paul, Lucy Burns and others —picketed outside the White House, burning copies of Woodrow Wilson’s speeches and demanding the right to vote. What resulted —mass arrests (most for “obstructing traffic”), unlawful imprisonment and bloody beatings —became known as the Night of Terror, though it’s fair to say most among my generation don’t know it.

The Night of Terror took place on Nov. 15, 1917, when the warden at the Workhouse Prison, in Occoquan, Virginia, ordered his guards to teach the suffragists a lesson. For weeks, the women’s only water had come from an open pail. Their food had been infested with worms. But on this night, some 40 prison guards wielding clubs beat the women senseless —grabbing, dragging, choking, kicking and pinching them, according to affidavits recounting the attacks.

...It would take three more years for women to win the right to vote.
