John Sarkander, Polish-Moravian priest and saint (b. 1576)
Jan Sarkander (Czech and Polish: Jan Sarkander) (20 December 1576 – 17 March 1620) was a Polish-Czech Roman Catholic priest. Sarkander was married for a short period of time before he became widowed and pursued a path to the priesthood where he became active in the defense of the faith during a period of anti-Catholic sentiment and conflict. He himself was arrested on false accusations as a means of silencing him and he refused to give in to his tormenters who tortured him for around a month before he died.

Pope Pius IX beatified Sarkander at Saint Peter's Basilica in 1860 and Pope John Paul II canonized him as a saint in 1995 on his visit to the Czech Republic.
