The Martyrs of Gorkum were a group of 19 Dutch Catholic clerics, secular and religious, who were hanged on 9 July 1572 in the town of Brielle by militant Dutch Calvinists during the 16th-century religious wars—specifically, the Dutch Revolt against Spanish rule, which developed into the Eighty Years' War.
