The devil seems to pop up everywhere in Czech culture, from children´s stories to curse words. But Lucifer wasn´t the beginning. Slav pagans believed that the land was haunted by malevolent demons who could ruin crops, cause bad weather or kill the unsuspecting. In fact, historians believe that demons and wicked spirits were more important to the Slav religion than gods. But how to we know that the modern devil is culturally related to the ancient demons? Well it´s all in the word. “Čert” (devil) hails from the ancient Slav “czart,” the name of a malevolent pagan demon who haunted bogs and springs.
