History isn’t just about knights in shining armor and noble rulers making wise decisions. Sometimes, it’s about bloodthirsty monarchs who ruled with iron fists, sharp swords, and a complete disregard for human life. From queens who orchestrated brutal betrayals to kings who turned mass executions into public entertainment, these rulers didn’t just crave power—they bathed in it.
If you think modern leaders are ruthless, wait until you meet these 10 medieval monarchs who took tyranny to the next level. Whether it was impaling enemies, burning heretics, or casually murdering their own family members, these rulers made sure no one—friend or foe—stood in their way. Buckle up, because history is about to get dark.

1. Isabella of France: Peak Mother-in-Law Energy
In 1326, Isabella launched a ruthless invasion of England to depose her husband, King Edward II. Not content with just taking his crown, she orchestrated his brutal murder. We’re talking about a full-scale invasion, a steamy affair, and a murder involving a red-hot poker (use your imagination).
She ruled England with her lover Roger Mortimer for three years until her teenage son Edward III seized power, arrested Mortimer, and had him executed for treason. Here’s a fun fact I learned while exploring Nottingham Castle: Edward III used a secret tunnel to arrest Mortimer, so nobody had any idea what was about to happen, and that tunnel is still there.
2. Vlad “Not Just Dracula” Tepes: The Original Stick-It-To-‘Em Guy
Long before vampires, Vlad III terrorized Europe with real-life horrors. As Prince of Wallachia (1448-1477), historical records confirm he executed between 20,000 people through impalement. His brutality wasn’t random – it was calculated psychological warfare. Ottoman chronicles describe a “forest” of 20,000 impaled victims that greeted Sultan Mehmed II’s army in 1462, and Vlad would host elaborate feasts among his dying victims.
His diplomatic style was equally brutal: when Ottoman envoys refused to remove their turbans, citing religious customs, he had them nailed to their heads. The Turks named him “Kazıklı Voyvoda” (the Impaler Prince), a title earned through his methodical approach to torture – stakes were carefully designed to prolong suffering for days. His victims included nobles, peasants, and anyone who challenged his authority, regardless of their status or origin.
3. Mary I: Making Regular Murder Look Amateur
Mary I of England earned her nickname “Bloody Mary” through calculated brutality. During her five-year reign (1553-1558), she ordered the burning of 280 Protestant heretics, averaging more than one execution per week.
She commanded children to witness their parents’ executions and specifically targeted pregnant women, allowing them to give birth before burning them at the stake. At Smithfield, she had bishops Latimer and Ridley burned slowly for maximum effect, turning executions into public spectacles of Catholic power.
4. Ivan the Terrible: Russia’s King of Overkill
Ever visited a Russian fortress? Ivan didn’t get his nickname for being fashionably late. He created his own personal murder squad called the Oprichniki, who rode around on black horses wearing dog heads – subtle, right?
Picture this: he beat his own son to death in a rage, then spent the rest of his life having epic guilt trips about it. One chronicle I studied mentioned that he ordered all Moscow’s dogs killed because their barking annoyed him. Someone wasn’t a pet person.
5. Richard II: The Boy King Who Became a Tyrant
Crowned at age 10 in 1377, Richard II transformed from England’s golden boy into its worst nightmare. He famously betrayed and executed peasant revolt leaders after promising reforms and later declared himself a divine being above earthly law.
His paranoia led him to create a personal army of 10,000 Cheshire archers to terrorize nobles, and he forced everyone to wear his personal badge on pain of death. His reign ended when he was deposed in 1399 and mysteriously starved to death in captivity – though whether by choice or force remains debated.
6. Eleanor of Aquitaine: A Queen Who Played for Keeps
As the only woman to be Queen of both France and England, Eleanor of Aquitaine mastered the medieval game of thrones through sheer political genius. After divorcing the King of France, she swiftly married the future Henry II of England. Still, when he crossed her, she supported their sons’ rebellion against him – earning herself 16 years of imprisonment.
She had the last laugh, though – outliving Henry to become regent for her son Richard the Lionheart, ruling effectively into her 80s and proving that sometimes the best revenge is simply surviving.
7. Theodora: Byzantine’s Most Ruthless Empress
From entertainer to emperor’s wife, Theodora’s rise shocked Byzantine society. While historical records first mention her as a Hippodrome courtesan, she transformed into one of history’s most brutal rulers after marrying Emperor Justinian I.
Her signature move? Having enemies’ tongues torn out and imprisoning rivals in palace dungeons until they died. Her crowning achievement in cruelty came during the Nika riots, where she orchestrated the massacre of 30,000 citizens trapped in the Hippodrome. Not bad for a former dancing girl.
8. King John: England’s Worst Boss Ever
From reluctant prince to tyrannical king, John of England’s reign was a disaster. The youngest son of Henry II, he schemed his way to the throne after his brother, Richard the Lionheart, died. But instead of securing power, he became infamous for losing land, trust, and even a crown—literally, sinking it in quicksand.
His signature move? Extorting nobles with crushing taxes and betraying allies at every turn. When his barons had enough, they forced him to sign the Magna Carta in 1215, limiting his power. He immediately tore up the deal, sparking a rebellion. Despised and deserted, he died of dysentery, leaving behind a legacy of failure. Not bad for a king called “Lackland.”
9. Wu Zetian: A Trailblazer with a Ruthless Edge
The imperial records in Xi’an tell quite a tale. Wu Zetian killed her own baby to frame a rival, invented something called the “Human Pig Cage” (exactly as pleasant as it sounds), and had a special torture method called the “chalk circle” where victims bled out while walking in circles. Her reign exemplified ambition at its most extreme.
10. Charles the Bad: A Fitting End
My favorite part about researching Charles? His karma-laden ending. After years of poisoning rivals and torching towns for giggles, he died when his alcohol-soaked medical wraps caught fire. I’ve seen the room where it happened – apparently, his screams of “hot-hot-hot” were his last words. Medieval medicine, am I right?
Why This Still Matters
After years of climbing castle towers and decoding medieval manuscripts, I can tell you one thing: power doesn’t corrupt – it just reveals who people are. These rulers might be long gone, but their castles still stand, their stories still echo, and honestly? They make our modern politicians look like amateurs. Next time you think your boss is evil, just remember – at least they’re not measuring you up for a human-sized pig cage!
