The event commemorates the peasant uprising in the 16th century against the nobility oppressing them.
The Croatian-Slovene Peasant Revolt of 1573 was a large peasant uprising on the territory forming modern-day Croatia and Slovenia. The revolt, sparked by the cruel treatment of serfs by Baron Ferenc Tahy, ended after 12 days with the defeat of the rebels and bloody retribution by the nobility. Matija Gubec, leader of the rebels, was publicly tortured, forced to wear a red-hot iron crown, cruelly dragged along the streets of the city, pinched with red-hot iron pincers, and subsequently executed.
