16 of the worst monarchs in history
From the morally bankrupt to the staggeringly inept, Jonny Wilkes guides us through the lives of 16 rulers who wrote their names into the history books for all the wrong reasons

The past has no shortage of disastrous kings, queens, and other rulers; such a list could easily have been filled with the worst Roman emperors alone. Some have been homicidal, like Nero or Genghis Khan; simply incompetent, like Edward II; completely untrustworthy, like Charles I; or amiable but inadequate, like Louis XVI of France.
But who are truly the worst, and why? Jonny Wilkes makes the case against 16 rulers from history…

1. Lucius Tarquinius Superbus
King of Rome, 534–509 BC
Before Rome had emperors, it had a line of kings going back to the city’s mythical founder, Romulus. The last, however, presided over a reign of terror so bad that the people gave up on the monarchy altogether, heralding the dawn of the Republic.
Lucius Tarquinius Superbus (commonly known as ‘Tarquin the Proud’) had seized the throne by planning the assassination of his own father-in-law, then once in power he killed senators on a whim and imprisoned or executed anyone suspected of disloyalty.
His undoing came when his son raped a noblewoman, which caused such outrage that a revolt broke out that saw the tyrannical king overthrown and exiled. In his doomed attempts to regain the throne, he persuaded neighbouring cities to attack Rome, seemingly unfazed by the damage this would do to his erstwhile kingdom.

2. Commodus
Roman emperor, 177–92 AD
There are a number of contenders to the title of ‘most despicable emperor of Rome’, so we could just as easily be discussing the cruel and murderous rules of, say, Nero and Caligula.
The bloodthirsty, vainglorious spendthrift, Commodus, however, went from inheriting an empire enjoying a long period of peace and prosperity, the Pax Romana, to leaving it broke and in turmoil. If not executing anyone he suspected of plotting against him, he was leaving the job of ruling the empire to a series of corrupt, cruel and incompetent favourites. He much preferred to fight as a gladiator, relishing in slaughtering a menagerie of animals in the arena.
No wonder, then, that Commodus was chosen as the villain in Ridley Scott’s swords-and-sandals masterpiece, Gladiator.

3. John
King of England, 1199–1216
Seriously, how could the arch-villain of Robin Hood not make an appearance? Beyond the tale of the fabled outlaw, John severely damaged the authority of the English monarchy. As a prince, he angered the nobles of Ireland and attempted to steal his brother Richard I’s crown, only ending up as king after Richard died without a legitimate heir. Notably, he also managed to outmanoeuvre a rival claim from his nephew, Arthur of Brittany, whom he is later believed to have had murdered.
Within a few years in power, John had lost Normandy – the foundation of his family’s Angevin empire on the continent – then he emptied the kingdom’s coffers trying to win it back. His oppressively high taxes, his clashes with the church and his cruel and conniving personality all led to a revolt of England’s barons.
Under threat of civil war, John was forced to seal Magna Carta, a historic document that limited royal power. He then proceeded to ignore it. The barons rose up again and John’s reign ended, dying of dysentery, as he fought to keep hold of his kingdom.

4. Wanyan Chenglin
Emperor of the Jin dynasty, 1234
On 9 February 1234, with the warriors of the Mongol empire besieging the city of Caizhou, the emperor of the Jin dynasty in China, Aizong, knew that his 10-year reign would be over shortly. That said, he did not want to be the last in his line, so he abdicated and passed the throne to his general, Wanyan Chenglin, before taking his own life.
The reluctant new emperor began a reign that would be doomed to last just a matter of hours. He was killed leading his soldiers in a last stand when the Mongols broke through the city walls.

5. Charles the Bad
King of Navarre, 1349–87
The name gives away why he belongs on this list, doesn’t it? Charles earned ‘the Bad’ for his duplicitous and treacherous behaviour in the Hundred Years’ War between England and France. Although King of Navarre in Spain, he owned a lot of land in northern France, which put him in the middle of the conflict, and his response was to keep flipping sides.
Driven solely by ambition, he believed he should be on the French throne, and he plotted and murdered to get it. All the while, Navarre went ignored. What made him truly bad, though, was that his schemes failed utterly. Charles is perhaps best-known today for his grisly end in 1387, when the brandy-soaked sheets he had been wrapped in to cure an illness accidentally caught fire, burning him alive.

6. Henry VI
King of England, 1422–61, 1470-71
Ascending the throne of England as an infant and the son of the hero of Agincourt, the young Henry VI was always going to struggle to live up to his dynastic legacy.
Not helped by his total lack of leadership, it went even worse than feared: he lost control of France (won by his father Henry V), suffered a mental breakdown, and saw his kingdom plunge into the Wars of the Roses. The Lancastrian cause would be headed not by the king, but his queen, Margaret.
Henry’s role amounted to being kicked off the throne by the Yorkist Edward IV, then placed back on it by the ‘kingmaker’, the Earl of Warwick, and finally losing it again after being captured.

7. Christian II
King of Denmark and Norway, 1513–23
Christian’s reign may seem more insignificant than terrible at first glance, but it signalled the end of the Kalmar Union, which had bound together the Scandinavian countries of Denmark, Norway and Sweden for well over a century. Having been crowned in the first two of those countries in 1513, he set out to secure the third.
It would not be until 1520 that he captured Stockholm, although, hardly magnanimous in victory, his immediate action was to execute 82 nobles. The so-called Stockholm Bloodbath fuelled a Swedish rebellion against Christian and weakened his authority back in Denmark and Norway.
He was overthrown and exiled, and then when he launched a desperate bid to win back his thrones by force, he was imprisoned for the rest of his life.

8. Ivan the Terrible
Tsar of Russia, 1547–84
As the first tsar, Ivan was in some ways an able ruler since he laid the foundations of the Russian empire. He became known as ‘the Terrible’ for a reason, though. Having hated the nobles from an early age (at 13, he had one fed to a pack of dogs), he wasted no time in purging the upper classes.
The domain he inherited clearly was not enough: he instigated numerous, and disastrous, wars of expansion, and even established his own fiefdom within his land where, essentially, anything went. With Ivan prone to paranoia and fits of rages, no one was safe: he ordered a full-on attack on one of his own cities, Novgorod, and beat his daughter-in-law into having a miscarriage, then murdered his son.

9. Rudolf II
Holy Roman Emperor, 1576–1612
Despite being hailed as a generous patron of the arts and sciences, Habsburg emperor Rudolf II utterly failed in his role as the leader of one of Europe’s major powers. Rather than focusing on politics and administration, he instead shut himself away to focus on personal pursuits like alchemy.
When he did show some determination – starting a war with the Ottoman empire to unify Christendom – it proved a disaster. His subjects in Hungary revolted and his family made him hand over power to his younger brother.
Rudolf’s most damning legacy, however, was that his miserable tenure as emperor has been blamed as one of the causes of the Thirty Years’ War, one of the bloodiest conflicts in history.

10. Louis XV
King of France, 1715–74
It could certainly be argued that Louis XV’s status as a poor king of France was overshadowed by his successor, Louis XVI, since he was the one who lost his head in the French Revolution. Yet Louis XV’s reign sowed the seeds of the people’s discontent that would lead to such a violent rejection of the monarchy. In short, he was a deeply ineffectual ruler, let alone the all-powerful absolutist king that France had become accustomed to under Louis XIV.
Reports of corruption and handing over influence to his mistresses hurt the crown’s authority, while his wars and extravagant spending depleted the coffers. France became a less powerful nation under his rule, and smaller too: he gave up New France in the Americas after the disastrous Seven Years’ War.

11. Ferdinand VII
King of Spain, 1808, 1813–33
Shortly after taking the throne in 1808, Ferdinand handed over his kingdom – and himself – to Napoleon Bonaparte. Six years of captivity in France later, he returned with a need to prove his absolutist credentials and so ditched Spain’s liberal constitution that had been written in his absence. This led to multiple uprisings, notably the revolt of 1820, which ushered in three years during which the king was forced to accept a constitutional regime.
While more selfish than monstrous, Ferdinand’s legacy and place on this list were confirmed by two things: he oversaw the loss of nearly all of Spain’s colonial territories in the Americas and, following his death, his petty bid to exclude his brother from the succession resulted in a long civil war.

12. Ranavalona I
Queen of Imerina, 1828–61
To try and hold back the wave of European colonisation in Africa, Queen Ranavalona I, of modern-day Madagascar, would go to any lengths. She wanted to purge all foreign influence, expelling missionaries, persecuting Christians and restricting trade. She even tried to have a giant pair of scissors made so that she could literally chop foreigners in half.
The ones who suffered the most, however, were her people: to preserve her land’s self-sufficiency and way of life, as she saw it, Ranavalona used forced labour for her royal projects and fear to maintain order.
Many executions took the form of the tangena ordeal, a witch-hunt-style trial where the accused was made to ingest poison and if they showed any adverse effects, they were deemed guilty. It is claimed that as much as 50 per cent of the population perished during her rule.

13. Leopold II
King of the Belgians, 1865–1909
Leopold II may not have been a terrible king in Belgium itself, but with the Congo Free State, he revealed just how much of a monster he could be. In 1885, he created his own state in central Africa, having convinced European powers that he intended to improve the lives of the people living there.
In reality, this privately owned kingdom allowed Leopold to exploit the Congolese people so that he could make money from its ivory and natural rubber reserves. Under his system of forced labour, any workers who failed to meet their quotas would be punished with mutilation. Leopold’s preferred method was chopping off hands and feet. Millions died from the brutality and rampant diseases.
This was an age where European empires carved up and exploited the African continent, so the fact that international outrage finally forced Leopold to hand over the Congo Free State illustrates the appalling extent of the atrocities.

14. Khalid ibn Barghash
Sultan of Zanzibar, 1896
Not only did Khalid ibn Barghash rule for just three days, but he was ousted in the shortest war in history. So, in truth, there is no knowing whether he would have been a bad ruler: there wasn’t enough time. In 1896, the sultan of Zanzibar died, which put the British in a tough position. They controlled the islands off the east African coast as it served as a strategic trade post for the Indian Ocean.
Against British wishes, Khalid, who may well have killed his predecessor, assumed the role of sultan and fortified the palace with around 3,000 supporters. The British sent warships, though, and initiated a brief bombardment. The Anglo-Zanzibar War lasted around 38 minutes, and Khalid fled into exile.

15. Nicholas II
Tsar of Russia, 1894–1917
The Romanov dynasty ruled Russia for more than 300 years – and it all ended during the reign of Nicholas II. Not suited to wielding autocratic power over a huge empire, he made a catalogue of errors and refused to adapt beyond his rigid belief that he had the divinely ordained right to rule.
In 1905 alone, Russia lost a war with Japan and broke out in revolution, yet Nicholas only made cursory changes and tried to move on. His court became dominated by the strange and ambitious mystic, Rasputin, his nobles and politicians abandoned him, and his decision to take command of the armies in the First World War meant that he was held personally responsible for every defeat and death.
Revolution erupted again in 1917, forcing his abdication. While imprisoned by the revolutionaries, Nicholas and his entire family were murdered. It was a bloody and definitive end to the tsars, as Russia became a communist regime.

16. Edward VIII
King of England, 1936
Edward became king on 20 January 1936, on the death of his father George V. Before the year was out, he had abdicated in disgrace. His brief reign had entirely been focused on his wish to marry an American named Wallis Simpson, but she had been divorced once and was seeking a second, making her wholly unacceptable to the royal family, the political establishment and the church.
Yet his reputation as a bad monarch could have been even worse had he stayed: Edward has long been accused of being a Nazi sympathiser, who toured Hitler’s Germany almost two years before the Second World War.
