These Are the Most Ruthless Leaders of all Time

Throughout the course of human history, dictatorial leaders have regrettably outnumbered philanthropic ones. This unsettling trend spans thousands of years, from ancient despots like Phalaris of Acragas to modern-day dictators like Hitler and Stalin. While the majority are male, there are a few exceptions, including the ruthless Chinese ruler Wu Zetian, who had no qualms about eliminating her rivals. T

ragically, it appears that acts of cruelty have not waned over time – in fact, half of the names on this list come from the last century alone, which could aptly be described as the “century of mass murder.” It’s a devastating reality, as figures like Joseph Stalin, Adolf Hitler, and so on have left a permanent stain on the pages of history books. To identify the most notorious and merciless leaders, CEOWORLD Magazine carefully examined various historical sources and compiled a list of 34 of the most tyrannical dictators.

1. Phalaris, the tyrant of Acragas (now Agrigento) in Sicily, gained notoriety for his extreme cruelty. His gruesome methods included roasting victims alive in a bronze bull. Ultimately, Phalaris met a similar fate himself after being overthrown from power.
2. Qin Shi Huang, the ruler of the Qin dynasty in China from 221 to 210 B.C., was known for his relentless pursuit of power. His reign involved the persecution of scholars and the burning of books. Despite the harsh methods, he successfully created the first unified Chinese empire, although it faced challenges soon after his death.
3. Herod the Great, a Roman client king of Judea from 37 to 36 B.C., is infamous for ordering the Massacre of the Innocents during the time of Jesus Christ’s birth, as recounted in the biblical Gospel of Matthew.
4. Caligula, the third emperor of Ancient Rome (37 to 41 A.D.), earned a reputation for cruelty. While notorious for his sadistic rule, he exhibited kindness towards his horse, Incitatus, whom he wanted to appoint as a Roman consul and priest.
5. Nero, the nephew of Caligula, ruled Ancient Rome from 54 to 68 A.D. Known for his ruthlessness, he was associated with murders, debauchery, and casual cruelty. The claim that he played a fiddle while Rome burned during the great fire of 64 A.D. may be negative propaganda from rivals.
6. Attila the Hun, leader of the Hunnic Empire from 434 to 453 A.D., became one of the most powerful leaders in history. His legacy is marked by attacks on the Roman Empire and the destruction of many conquered cities.
7. Wu Zetian, who ruled China during the Tang dynasty from 690 to 705 A.D., stands out as one of the few women on the list. Her more than half-century rule was characterized by mercilessly eliminating rivals, including family members.
8. John I of England, known as “Bad King John,” ruled England from 1199 to 1216. His cruelty during the early 13th century earned him a place as the villain in the Robin Hood stories.
9. Genghis Khan, who founded the Mongolian Empire and ruled from 1206 to 1227, united the tribes of Northeast Asia through ruthless means, including eliminating rivals. His name has become synonymous with the brutal exercise of power.
10. Timur, also known as Tamerlane, was a Mongol ruler of the Timurid Empire from 1370 to 1405, over 150 years after Genghis Khan. His military campaigns are estimated to have caused the death of millions.
11. Vlad Tepes, ruling Wallachia (Romania) in 1448, 1456-1462, and 1476-1477, was known as “Vlad the Impaler” for his preferred method of dealing with opponents. He is said to have inspired Bram Stoker’s character Dracula.
12. Henry VIII, ruling England from 1509 to 1547, oversaw the creation of the Church of England and had two of his wives executed during his more than three-decade reign.
13. Ivan the Terrible, the first Tsar of all Russia, ruled from 1547 to 1584. While transforming Russia into an empire, his rule came at immense cost to its people.
14. Mary I, also known as “Bloody Mary,” was the first queen of England to rule in her own right from 1553 to 1558. Her persecution of Protestant heretics, burning many at the stake, earned her the notorious epithet.
15. Ibrahim I, an Ottoman Sultan ruling from 1640 to 1648, experienced a reign marked by war and rebellion.
16. Ranavalona I, ruling Madagascar from 1828 to 1861, earned the monikers “Mad Queen of Madagascar” and “Ranavalona the Cruel.” Her reign witnessed a significant reduction in the country’s population.
17. Leopold II, King of Belgium from 1865 to 1909, ruled the Congo Free State as a personal possession, resulting in a population decrease due to executions, illness, and malnutrition.
18. Mehmet Talat Pasha, influential in the Ottoman Empire from 1913 to 1918, was described as the principal architect of the 1915 Armenian Genocide.
19. Benito Mussolini, the dictator of Italy from 1922 to 1943, allied with Adolf Hitler’s Germany, leading Italy to disaster and defeat in World War II.
20. Joseph Stalin, ruling the Soviet Union from 1922 to 1953, governed through terror, resulting in the deaths of millions due to purges, famine, and war.
21. Adolf Hitler, who led Germany from 1933 to 1945, bears responsibility for both World War II and the Holocaust, making him almost unique in ruthlessness.
22. Francisco Franco, the dictator of Spain from 1938 to 1975, ruled for 40 years after winning the Spanish Civil War, with many opponents executed or imprisoned.
23. Khorloogiin Choibalsan, known as the “Stalin of Mongolia,” led Mongolia from 1939 to 1952, initiating a political purge resulting in the deaths of tens of thousands.
24. Mao Zedong, ruling China from 1949 to 1976, attempted to create a communist paradise but caused a famine, resulting in the deaths of at least 45 million people.
25. Kim Il-Sung, dictator of North Korea from 1949 to 1994, led the country into the Korean War, implemented disastrous economic policies, and committed human rights abuses.
26. François Duvalier, who ruled Haiti from 1957 to 1971, known as “Papa Doc,” lived luxuriously while his people experienced poverty and hunger. His paramilitary police force, the Tonton Macoute, caused countless disappearances.
27. Jean-Bédel Bokassa, styling himself as Emperor of the Central African Republic from 1966 to 1979, faced accusations of cannibalism and feeding opponents to animals.
28. Idi Amin, in power in Uganda from 1971 to 1979, came to power in a military coup and is believed to have killed 300,000 opponents, expelled Indians and Pakistanis, and destroyed the country’s economy.

32. Saddam Hussein, the brutal dictator of Iraq from 1979 to 2003, killed tens of thousands of Iraqis during his 14-year rule and was overthrown in a war with the United States.
33. Slobodan Milošević, president of Serbia and later the Federal Republic of Yugoslavia from 1989 to 1992 and 1997 to 2000, was the first European head of state to be prosecuted for genocide and war crimes.
