Who conquered more, Hannibal or Genghis Khan?

Genghis Khan, by far. On Rein Taagepera's estimate his empire covered about 13.5 million km² when he died in 1227. Hannibal won great battles in Italy but never ruled an empire, and Carthage lost the war.

Did Hannibal ever lose a battle?

Yes. His decisive defeat came at Zama in 202 BC against Scipio Africanus, which ended the Second Punic War. Before that he had won great victories at the Trebia, Lake Trasimene and Cannae.

Did Genghis Khan ever lose a war?

No war he led ended in defeat. He conquered or forced the submission of the Western Xia, the Jin and the Khwarazmian Empire, and died in 1227 during a final campaign against the Western Xia. No complete record of every battle he fought survives.

Genghis Khan vs Hannibal: Who Was the Greater Commander?

Q: Who lived first, Hannibal or Genghis Khan?

Hannibal. He was born in 247 BC and died around 183 BC, while Genghis Khan was born around 1162 and died in 1227, about fourteen centuries later. They never met.

Q: Would Genghis Khan beat Hannibal?

It is impossible to know. Mongol horse archers would have posed problems Hannibal never faced, as the Parthian victory over Crassus at Carrhae in 53 BC suggests, but Hannibal was a master of cavalry and of traps, and his armies were not Crassus's.

Quick answer

Who was the greater commander, Genghis Khan or Hannibal?

It depends on the measure. Genghis Khan conquered far more, an empire of about 13.5 million km² by his death in 1227, and built the army that did it. Hannibal was the finer battlefield tactician, above all at Cannae in 216 BC, but he lost his war against Rome at Zama.¹

One crossed the Alps with elephants and fought on in Italy for some fifteen years, destroying one Roman army after another. The other united the tribes of the Mongolian steppe and launched the conquests that built the largest contiguous land empire in history. Hannibal Barca and Genghis Khan never met, and fourteen centuries lie between them, but people keep asking which of them was the greater commander. The honest answer depends on what you measure.²

Key points

Hannibal lived first, about fourteen centuries before Genghis Khan.
Genghis conquered vastly more: about 13.5 million km² by 1227, while Hannibal never ruled an empire.
Hannibal is the battlefield artist: Cannae is still studied as the model of an encirclement.
Hannibal lost his war at Zama; Genghis lost none of his wars and died with his empire still growing.

Who lived first, Hannibal or Genghis Khan?

Hannibal, by roughly fourteen centuries. He was born in 247 BC and died in exile in Bithynia around 183 BC; the ancient writers give dates between 183 and 181 BC. Genghis Khan was born, most historians think, around 1162, and died in August 1227. About 1,400 years separate their births.¹⁹

Who conquered more?

Genghis Khan, beyond any comparison. On Rein Taagepera's estimates the Mongol realm grew from about 4 million km² in 1206 to about 13.5 million km² when Genghis died in 1227, and under his heirs it reached about 24 million km². Hannibal conquered no empire. He won battles on Rome's own soil and held out in Italy for some fifteen years, until Carthage recalled him in 203 BC.²⁰

Strategy

Hannibal's strategy was daring and, in the end, unsuccessful. He took the war to Italy over the Alps in 218 BC and hoped to break Rome's alliances by beating its armies in the field. Livy has his cavalry commander Maharbal tell him after Cannae: “You know how to win victory, Hannibal”, but not how to use it. Rome refused to make peace, rebuilt its armies and in the end beat him at Zama.²¹

Genghis Khan fought a sequence of wars of conquest: against the Western Xia from 1209, the Jin from 1211, a war he never finished, though their capital Zhongdu fell in 1215, and the Khwarazmian Empire in Central Asia, whose cities of Bukhara and Samarkand fell in 1220.²²

Tactics

On the battlefield Hannibal has few equals. At the Trebia in 218 and Lake Trasimene in 217 BC he trapped Roman armies, and at Cannae in 216 BC he let the Roman center push into his line while his cavalry closed the ring behind it. Polybius puts the Roman dead at about 70,000; Livy at 45,500 infantry and 2,700 cavalry. Read the full story of the Battle of Cannae.²³

Genghis Khan's armies won with mounted archers, speed and maneuver, and with engineers: after 1212 they recruited Jin siege experts, and World History Encyclopedia notes that they adopted Chinese catapults. For how the steppe way of war worked, see our guide to horse archers.²⁴

Logistics and organization

Here Genghis Khan is in a different league, because he built the machine he fought with. He reorganized the Mongol army into units of tens, hundreds, thousands and ten thousands, cutting across tribal loyalties, created a guard, the keshig, that grew to 10,000 men, and set up the yam, a network of relay stations that his son Ögedei later expanded.²⁵

Hannibal had no such state behind him. He fought for years in enemy territory with an army of Africans, Spaniards and Gauls, and the reinforcements he needed rarely reached him.²⁶

Leadership

Both men held together armies of many peoples. Hannibal kept a mixed force loyal through long years in Italy. Genghis Khan united rival steppe tribes and rewarded loyalty above birth. Mongol conquests also brought great destruction in the cities that resisted, though the death tolls given by medieval chroniclers are considered exaggerated and cannot be checked.²⁷

Would Genghis Khan beat Hannibal?

Nobody can know, and any answer is a guess. The nearest ancient test of horse archers against a Roman-style army is Carrhae in 53 BC, where about 9,000 to 10,000 Parthian horse archers and 1,000 armored cavalry destroyed the army of Crassus; about 20,000 Romans were killed and 10,000 captured. Hannibal, though, was not Crassus: his own strength was cavalry, and he won his greatest battles by drawing enemies into traps. A Mongol army would likely have tried the same kind of trap on him.²⁸

So who was better, Genghis Khan or Hannibal?

As a conqueror and organizer, Genghis Khan: he left an empire of about 13.5 million km² and an army system his heirs used to nearly double it. As a battlefield tactician, many historians give Hannibal the edge, since Cannae remains the classic encirclement. But Hannibal lost his war, and Genghis never lost his.²⁹

Hannibal himself, as a famous story has it, ranked Alexander the Great first among generals, Pyrrhus second and himself third. Livy reports it only on the authority of Claudius, who followed the Greek history of Acilius, and his own account names another envoy, Villius, as the Roman who met Hannibal at Ephesus, so the conversation may be invented.
