List Rules Vote up the brutal monarchs you really wouldn't want ruling your country.

It's no secret that the word "medieval" evokes negative images, but in the case of these Middle Ages monarchs, those connotations are well-deserved. From callous queens to cutthroat kings and savage saints, we're taking a look at the most brutal monarchs from medieval times who played by their own bloody rules

So what caused such monarchical madness? Some slaughtered thousands while trying to spread Christianity and expel beliefs they disliked; others nudged tensions between sects of Christianity along, resulting in a mob mentality that took the lives of tens of thousands. Other brutal monarchs, including a number of late medieval Italian royals, enjoyed torturing their enemies in new and creative ways, such as forcing furriers to eat hares whole or creating mummy museums by pickling their rivals. Some kings didn’t bother disguising their ambitions, and just added to their burgeoning empires by taking city after city and slaying opponents and new subjects wholesale.

Whatever their reasons for taking out their lovers, friends, and enemies, read through this list and vote up the most violent medieval monarchs.

  • Royal Title: Temujin, Great Khan of the Mongol Empire
  • Most Brutal Moment: While carving out a massive empire that stretched across millions of square miles, Genghis Khan and his nomadic Mongolian soldiers took millions of lives. The Mongols once ended an estimated 1.2 million lives while sacking a single city. That's right, over 1 million people in only one battle.  In fact, one commentator reported that the Great Khan vanquished so many enemies that their bones formed mountains and the dirt became oily with human fat.

Some of his bloodier moments include using young men as human shields and organizing mass rapes. The latter event probably resulted in many children, making Genghis Khan a direct ancestor of 16 million people today.

Galeazzo Maria Sforza

  • Royal Title: Galeazzo Maria Sforza, Duke of Milan
  • Most Brutal Moment: A master torturer and true evil mastermind, Galeazzo Maria once chopped off a rival's hands and ended a poacher by making him swallow an entire hare.

This 15th-century duke of Milan came by his brutal personality honestly. The surname of his warlord-turned-noble family, Sforza, means "force" in Italian. One contemporary writer recorded how Galeazzo Maria, upon asking a priest how long he would reign in Milan and being told only 11 years, stuck the good father in jail with just a little bit of food. As the story goes, "The man survived on these things, even getting to eat his own excrement, for twelve days. Then he died." Galeazzo Maria was also accused of organizing group assaults on women and dosing his own mother.

  • Royal Title: Ferdinand I, King of Naples
  • Most Brutal Moment: Slaying his rivals and building a "museum of mummies" with their remains in his palace.

Born the illegitimate son of a Spanish monarch, Ferdinand enjoyed keeping his deceased enemies around. Once, he invited some French "pals" (AKA agents of his rival to the throne of Naples) to dinner. After they ate, he then imprisoned others for 30 years, even shoving one guy out of a window to his demise. Some were propped up in a mock banquet at Castel Nuovo; the bodies were pickled and turned into mummies, then redressed to look lively.

  • Royal Title: Olaf Tryggvason, King of Norway
  • Most Brutal Moments: A Viking warrior par excellence, Olaf wasn't afraid of getting his hands dirty - and bloody - when it came to slaying pagans and the treacherous (he once beheaded a slave who took out a royal rival for him). 

In the 13th and 14th centuries, Olaf began to appear in poems as the slayer of a man named Raud, a determined follower of Thor. Despite Raud's best magical efforts, legend has it that Olaf's Christian faith dominated, but when Raud refused to accept Christ, Olaf forced a snake into his mouth using a red-hot iron. The serpent went through Raud's neck and ended him. Olaf took Raud's gold, dispatched his followers that wouldn't convert, and brought those that would be baptized into his fold.
