Bartholomew's Day, St., 24th August, day in 1572 memorable for the wholesale massacre of the Protestants in France at the instance of Catharine de Medici, then regent of the kingdom for her son, Charles IX., an event, cruelly gloried in by the Pope and the Spanish Court, which kindled a fire in the nation that was not quenched, although it extinguished Protestantism proper in France, till Charles was coerced to grant liberty of conscience throughout the realm.
