An Abolitionist’s Refusal
Abolitionists William Still and Passmore Williamson rescued the Johnson family enslaved to the U.S. Ambassador to Nicaragua. Served with a writ of habeas corpus that required him to produce the Johnson family, Williamson refused and was jailed. The case became both an international and a national cause célèbre of the abolitionist movement.
