Martyrs of Alkmaar
The Martyrs of Alkmaar were a group of 5 Dutch Catholic clerics, secular and religious from Alkmaar, who were hanged on 24 June 1572 in the town of Enkhuizen by militant Dutch Calvinists during the 16th-century religious wars—specifically, the Dutch Revolt against Spanish rule, which developed into the Eighty Years' War. These atrocities were inflicted by the Calvinist leader, Diederik Sonoy.
