Hungarian kids don't watch horror movies. They go to history class.
Dózsa György was a soldier in the wars against the Turks at the end of the 15th century (I know you are sensing a trend here, we'll go to other eras too, I promise). He was good at what he was doing - fighting - so much that in 1514 he defeated a Turkish captain in single combat. The king honored him with money, property, and knighthood.
His execution is one of those images that are burned (no pun intended) deep into the Hungarian mind. He was seated on a mock throne and crowned with a glowing hot iron crown (as a parody of him leading an army against the kingdom). After that, the executioners made his closest followers eat parts of him.
Yeah, you read that right.
According to a popular version of the story the throne was burning hot too, but contemporary sources don't support that claim. It was probably made up later to add to the horror of the means of execution. Dózsa was revered later in Hungarian history as a "freedom fighter" against the oppression of nobility, and he is still an iconic character we all learn about in history class.
