If you think medieval monarchs were all prim and proper, prepare to meet a lineup of the most badass medieval figures whose nicknames sound more like punchlines than regal titles. From blood‑thirsty Vikings to scheming French kings, these leaders wore their monikers like battle‑scarred armor.
Why These Badass Medieval Monarchs Matter
Beyond the colorful epithets lies a tapestry of power struggles, daring escapes, and ruthless politics that shaped entire regions. Their stories prove that a memorable nickname can be both a warning and a badge of honor.
10 Lugaid ‘Son Of A Bitch’ High King Of Ireland
Early Irish chronicles are as reliable as a caffeine‑fueled babysitter, yet they tell us that Lugaid seized the throne at Tara around AD 200. Known as “Mac Con,” which translates to “Son of a Bitch” (or literally “Son of the Hound”), the nickname sprang from a bizarre childhood episode: the infant Lugaid allegedly suckled from the teats of his stepfather Ailill “Nude‑Ear’s” hunting dog.
Growing up into a quarrelsome youth, Lugaid allied with a rebel named Nemed to battle both Nude‑Ear and the High King Art mac Cuinn. After Nemed fell, Lugaid was dispatched to Scotland, only to return later with an army, slay King Art, and claim the crown at the Battle of Mag Mucrama—literally the “Plain of Pig‑Counting.”
He later adopted Art’s son Cormac, ruled for seven years, and was eventually deposed by the ungrateful bastard. Seeking refuge with his stepfather, Lugaid received a brutal bite on the cheek from Nude‑Ear’s foul‑toothed maw. The wound festered for three days, and as Lugaid tried to flee, a warrior caught him and speared him straight through the face.
9 Ragnarr ‘Hairypants’ Chief Of The Vikings
Ragnarr, a mid‑ninth‑century Scandinavian chieftain, earned the fearsome epithet “Loobrok,” which translates to “Hairypants” (sometimes rendered “Hairy Breeches”). Legend claims the moniker arose from a pair of cow‑hide leggings he wore while battling a venomous serpent.
His reign was marked by church‑burning raids and Christian massacres until King Aella of Northumbria captured him and tossed him into a pit of adders—presumably without his protective, fuzzy trousers. Ragnarr’s notorious sons—Ivar “the Boneless” and Sigurd “Snake‑in‑the‑Eye”—later formed the Great Heathen Army and exacted a bloody revenge on Aella.
Some scholars argue Ragnarr is a composite saga hero, but a possible historical seed is Reginheri, a pillager whose fatal bout of diarrhea left his pants matted and, by extension, “hairy.”
8 Ludwig ‘The Leaper’ Count Of Thuringia
In the mid‑11th century, Ludwig the Bearded ruled Thuringia. To set himself apart from his similarly hirsute father, Ludwig Jr. tried to claim the Saxon county palatine, only to discover Frederick already held the title. Undeterred, Ludwig stabbed Frederick, prompting his henchmen to imprison the Count in a tower.
After three years of confinement, his captors grew weary of his constant hopping around the cell and announced his execution. Seizing the moment, Ludwig leapt from the tower into the Saale River, clambered onto a waiting boat, and rode away on his favorite horse—earning him the nickname “der Springer,” the Leaper.Never one to let a good view go to waste, Ludwig later eyed a mountain outside his borders, carted in soil from his own lands, piled it atop the peak, and erected the Wartburg castle—a fortress that still dominates the skyline today.
7 Louis ‘The Universal Spider’ King Of France
While some historians label him “the Prudent” or “the Cunning,” the more vivid nickname for Louis XI was “l’Universelle Aragne”—the Universal Spider—reflecting his talent for weaving intricate webs of intrigue rather than for any penchant for flies.
As Crown Prince, Louis raised armies against his own father, Charles “the Well‑Served,” and even insulted the king’s lover. He later married a twelve‑year‑old princess, a match his father disapproved of. When Charles died in 1461, Louis ascended the throne and swiftly ended a 116‑year war with England.
He then turned his cunning toward Charles “the Bold,” Duke of Burgundy, delegating the fight to the Swiss. A Swiss poleax felled the Duke, turning him from “the Bold” into “the Dead.” The rest of Louis’s reign saw economic reforms, consultations with astrologers, and a legacy that lives on in the works of Shakespeare, Sir Walter Scott, and Victor Hugo.
6 Vsevolod ‘The Big Nest’ Grand Prince Of Vladimir
Vsevolod was born into the sprawling family of Yuri “Long‑Arms,” who already had ten heirs. His mother Helene whisked him away to Constantinople after Yuri’s death, where he spent his youth amid Byzantine splendor.
At sixteen, Vsevolod married the Ossetian princess Maria Shvarnovna. His nickname “Balshoe Gniezdo” (Big Nest) references the fourteen children he later sired with Maria. Three years into the marriage, Vsevolod returned to Kiev, outmaneuvered his brothers, and reclaimed his father’s realm.
Kidnapped shortly thereafter, he was ransomed by his elder brother Mikhalko, who then died, leaving Vsevolod the city of Vladimir. He responded by crushing dissent, terrorizing the nobility, pillaging neighboring lands, and cementing alliances through the marriages of his many daughters. He also proclaimed that Vladimir’s rulers would henceforth be titled Grand Princes, a testament to his ambition and prolific progeny.
5 Wladyslaw ‘Spindleshanks’ Duke Of Poland
The moniker “Laskonogi,” or “Spindleshanks,” alludes to Wladyslaw III’s unusually long, thin legs. He was the fifth son of Duke Mieszko “the Old” of Poland and was exiled early by a jealous half‑brother. By 1202, a brutal family feud had eliminated his four older brothers and his father, leaving the throne within his reach.
Wladyslaw’s reign lasted a mere four years before disgruntled nobles rebelled and ousted him. He then spent the rest of his life locked in a perpetual struggle against archbishops, relatives, and rival warlords. His chief adversary was his nephew, Wladyslaw “the Spitter,” and the two were so consumed by mutual hatred that they often ignored external threats to focus on killing each other.
In his late sixties, he briefly reclaimed the dukedom, only to be driven out again two years later. The final chapter of his life saw him indulging in prostitution, and when he finally tried to seduce a woman, she turned the tables and killed him.
4 Alfonso ‘The Slobberer’ King Of Leon
Alfonso IX ascended the throne of León and Galicia in 1188, earning the nickname “El Baboso” (The Slobberer) for his habit of spitting during fits of rage. His kingdom was squeezed between the powerful Castile and the Moorish realms, prompting him to lead drool‑soaked invasions against both.
His marital life was equally tumultuous. After an annulment of his marriage to his first cousin Theresa of Portugal by a papal legate, he married another cousin, Berengaria of Castile. Pope Celestine III intervened, forcing him back to Theresa, yet Alfonso persisted, marrying and divorcing with the same reckless abandon.
Beyond the chaos, Alfonso founded Spain’s first university at Salamanca and convened the Cortes Generales—one of Europe’s earliest parliaments. His son Ferdinand later became king of Castile and León, paving the way toward a united Spain.
3 Olaf ‘Little Snack’ King Of The Isles
Vikings loved giving their most imposing leaders ludicrous monikers, and Olaf, who ruled the Hebrides and the Isle of Man in the mid‑12th century, was no exception. Known as “Bitlingr” (Morsel) or “Kliningr” (Bread and Butter), his nickname implied a bite‑sized stature despite his formidable presence.
After a brother named Lagman castrated another sibling, Olaf sought refuge in England while Lagman vanished after 1100. Seizing the opportunity, Olaf returned to his islands, which were under Orcadian attack, and, with the help of his son‑in‑law Somerled, repelled the invaders and assembled a fleet so powerful that no one dared challenge him.
Olaf also maintained a sizeable harem and fathered many children. After four decades of iron‑fisted rule, his own nephews conspired to kill him. His son Godred avenged the murder by blinding two of the conspirators and slaying the third.
2 –tyname’ Emperor Of Byzantium
Constantine V earned the derisive nickname “Copronymous,” meaning “Dung‑Named,” after rivals spread a rumor that the infant emperor soiled his baptismal font. He ruled during a period of external pressure from Arabs and Bulgarians and internal strife between iconodules (image worshippers) and iconoclasts (image destroyers).
An avowed iconoclast, Constantine defeated a coup led by his brother‑in‑law Artabasdos, blinding the usurper and his children. He then launched a ruthless campaign: destroying religious icons, lynching abbots, and forcing rebellious monks to marry nuns. Contemporary chroniclers described him as a “pernicious, crazed, bloodthirsty, and most savage beast.”
Despite the turmoil, Constantine achieved military successes, invading Syria, crushing the Arab navy, and slaughtering the Bulgarians. He died in 775 from swollen legs, a demise his enemies claimed was divine retribution. Later, iconodule opponents exhumed his remains and tossed them into the sea.
1 Ivaylo ‘The Cabbage’ Tzar Of Bulgaria
In 13th‑century Bulgaria, swineherd Ivaylo rose against a backdrop of disease, famine, and relentless Mongol raids. In 1277, he rallied a peasant army and challenged the complacent nobility. Nobles derided him with nicknames like “Bardovka” (Radish) and “Lahanas” (Cabbage).
Ivaylo’s boldness paid off: he personally slew the chariot‑riding tzar, seized the crown, and married the queen. He ruled for a single year, during which Byzantine forces attempted to dethrone him, but he outmaneuvered their armies.Eventually, a royal relative rallied the salad‑hating nobles, forcing Ivaylo to flee to his former enemies—the Mongols. Unwilling to aid a man named after a vegetable, the Mongols assassinated him two years later. Nevertheless, he is remembered for leading one of the earliest popular uprisings in medieval Europe.
