Unfairly Prosecuted Persons Day is observed on April 13 in Slovakia as a day of remembrance for the aggression against monks during the communist regime in Czechoslovakia. While it is not a public holiday, various businesses, organizations, and Christian communities participate in commemorative activities and events. The observance honors the priests and monks who suffered persecution, particularly highlighting the events of April 13, 1950, when state police arrested over 2,000 male monks from 56 monasteries. Although Czechoslovakia has since split into the Czech Republic and Slovakia, the latter continues to recognize this day to remember the injustices faced by religious figures during the communist era.
