Černová Tragedy Day is observed in Slovakia every October 27 to commemorate the tragic events of 1907 when Slovaks were killed by Hungarian police. The day honors the memory of the villagers from Černová, the birthplace of Andrej Hlinka, a prominent Slovak parish priest and public activist who advocated for Slovakia's independence from the Austro-Hungarian Empire. Hlinka had initiated the construction of a Catholic church in Černová, which was completed shortly before the consecration ceremony. On the day of the ceremony, villagers peacefully protested against the bishop's decision to proceed without Hlinka, resulting in a violent confrontation where 15 villagers were killed and many others were injured. This event remains a significant part of Slovak history, and the nation observes Černová Tragedy Day annually to remember those who lost their lives.
