What was Genghis Khan’s IQ?
The only number online for his IQ is an open-ended “130+” with no test behind it — the stronger case is a fatherless, illiterate boy who built the largest contiguous land empire in history.
No IQ test result exists for Genghis Khan, who died in 1227, and the only number that surfaces for his IQ, an open-ended “130+,” cites no test. What is documented is an empire founded at a 1206 kurultai by an illiterate chieftain’s son, organized on decimal lines and promotion by merit, that had already more than tripled in size by his death in 1227. From that record, this page’s estimate of his IQ level is 130–150.
Genghis Khan’s estimated IQ
- In 1206 a kurultai at the source of the Onon River proclaimed him sole ruler of the steppe under the title Genghis Khan, capping a rise that included defeating the Merkit (c. 1196), the Tatars (1202), the Kerait (1203) and the Naiman (May 1204); by his death in 1227 the state he founded had grown from about 4 million to about 13.5 million square kilometers, more than tripling in his own lifetime (Wikipedia’s Mongol Empire land-area figures).
- He reorganized the army into decimal units of ten (arban), a hundred (jaghun) and a thousand (minqan), conscripting every man between fifteen and seventy, and, according to the historian Paul Ratchnevsky, promoted men on ability rather than birth: two of his commanders, Jelme and Subutai, were sons of blacksmiths.
- After defeating the Naiman in 1204 he had their captured scribe, Tata-tonga, adapt the Uyghur alphabet to the Mongolian language and teach it to his own sons — the Mongols’ first written script for their own tongue — despite being, in the words of medievalists.net’s Jack Wilson, “an otherwise illiterate Mongol nomad” who left no writing of his own in any script.
- His administration exempted the clergy of every religion it encountered, including Buddhist, Christian, Taoist and Muslim clergy, from taxation and public service, a tolerance the Persian historian Juvaini says extended to permitting the Muslim call to prayer during the Khwarazmian campaign of 1219–1221.
- He proclaimed the Yassa, an oral law code, at the same 1206 kurultai that named him khan, and used it to govern an empire that, under his own direct command, expanded from the Mongolian steppe into northern China and Central Asia within about two decades.
Genghis Khan died in 1227, roughly 680 years before the Binet–Simon test of 1905, so this Genghis Khan IQ level is a modern judgment of a documented record, not a recovered score. The record is thinner than it looks: the fullest near-contemporary account, The Secret History of the Mongols, is anonymous, compiled at a date scholars still dispute (1228 to 1264), and opens with a semi-mythical genealogy; his birth year and even the cause of his death are also disputed. Unlike Julius Caesar or Alexander the Great, also profiled on this site, no writing in Genghis Khan’s own hand survives in any script, and by scholarly account he never learned to read or write at all, so this range rests entirely on organizational and military achievement, with no test and no personal text to check it against.
- Born
- c. 1162 (sources disagree: 1155, 1162 or 1167); birthplace also disputed, on the Onon River in what is now Mongolia or Russia
- Died
- 18 or August 25, 1227, at Xingqing, Western Xia (present-day northern China); cause disputed, burial site unknown
- Title
- Founder and first khan of the Mongol Empire, proclaimed at a kurultai in 1206
- Literacy
- By scholarly account, personally illiterate; ordered the Uyghur script adapted for the Mongolian language after 1204
- Empire, 1206–1227
- About 4 million km² at founding to about 13.5 million km² at his death
- Key reforms
- Decimal army (units of 10, 100 and 1,000), the Yassa law code (1206), merit-based promotion, tax-exempt clergy of all faiths
- Major campaigns
- Western Xia (from 1209), the Jin dynasty (from 1211), the Khwarazmian Empire (1219–1221)
- Primary source
- The Secret History of the Mongols, an anonymous Mongolian chronicle compiled some time between 1228 and 1264
What an IQ of 130–150 actually means
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
Average is 100 by construction, and about two-thirds of people fall between 85 and 115. Take the test to place your own score on this scale.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.

Temüjin, the future Genghis Khan, was born into the Borjigin clan of the Mongols, the son of the chieftain Yesügei and his wife Hö’elün, of the Olkhonud clan. Even his birth is disputed: historians favor 1155, 1162 or 1167, and Wikipedia notes that 1162, the date most historians accept, rests on the judgment of the historian Paul Ratchnevsky, who thought Temüjin himself may not have known the truth of it. The Secret History of the Mongols places his birth at Delüün Boldog on the Onon River, a site since argued over between Dadal in Mongolia’s Khentii Province and southern Agin-Buryat Okrug in Russia. When Temüjin was about eight, Yesügei was poisoned by Tatars who recognized an old enemy and slipped it into his food on the ride home; most of his father’s people then renounced the family for the rival Tayichiud, and Hö’elün raised her children on roots, small game and fish. Temüjin was later captured by the Tayichiud, escaped during a feast, and was sheltered for three days at personal risk by a man named Sorkan-Shira.
He had been betrothed at eight to Börte, daughter of an Onggirat chieftain, and married her at fifteen; around the same age he had already sworn the anda, or blood-brother, pact with another well-born boy, Jamukha, and separately won the patronage of Toghrul, khan of the Kerait and his own father’s anda. Over the eight years between the Merkit campaign, fought with Toghrul’s and Jamukha’s help around 1196, and the defeat of the Naiman in 1204, Temüjin turned on each ally in turn: the Tatars in 1202, after which he executed their leaders and absorbed their warriors; Toghrul’s own Kerait, who beat him at the Battle of Qalaqaljid Sands before he regrouped and routed them in a three-day battle in 1203; and finally the Naiman at the Battle of Chakirmaut in the Altai Mountains in May 1204, where their khan Tayang was killed. Jamukha, betrayed by his own men that same year, was executed; the Secret History of the Mongols says he asked his former anda for an honorable death.
At a kurultai called at the source of the Onon River in 1206, the assembled Mongols proclaimed Temüjin sole ruler of the steppe under the title Genghis Khan, and the same gathering proclaimed the Yassa, an oral law code that became the de facto law of the new state. He organized every man between fifteen and seventy into decimal units of ten (arban), a hundred (jaghun) and a thousand (minqan), and, according to Ratchnevsky, promoted men on ability rather than birth: two of his commanders, Jelme and Subutai, were sons of blacksmiths. None of it was written by his own hand. By the account of medievalists.net’s Jack Wilson, Genghis Khan was “an otherwise illiterate Mongol nomad” who nonetheless had a Uyghur scribe captured from the defeated Naiman, Tata-tonga, adapt the Uyghur alphabet to the Mongolian language and teach it to his own sons — the Mongols’ first written script for their own tongue — though no evidence survives that Genghis Khan ever learned to read or write it himself.
Genghis Khan raided Western Xia in 1207, invaded fully in 1209, then turned on the Jin dynasty of northern China after a March 1211 kurultai. In 1219 he invaded the Khwarazmian Empire after its governor at Otrar, Inalchuq, seized a Mongol caravan and executed its members as spies; Mongol armies took Bukhara, Samarkand and Gurganj, in a campaign Wikipedia calls among the bloodiest in human history, with casualties estimated between two and fifteen million. His administration exempted the clergy of every religion it encountered — Buddhist, Christian, Taoist, Muslim — from tax and public service; Juvaini, a Persian historian, says this extended to permitting the Muslim call to prayer during the campaign. He died on 18 or August 25, 1227 campaigning against Western Xia, of a cause historians still dispute (above), and his burial site was never recorded. The empire he founded at about 4 million square kilometers in 1206 covered about 13.5 million by his death and, under his successors, about 23.5 million by 1294 — by Wikipedia’s account, the largest contiguous empire in history.

Genghis Khan: the documented record
The estimate above rests on this record. Every entry here is a matter of public fact, which is more than can be said for the number itself.
- c. 1162Born Temüjin into the Borjigin clan, son of the chieftain Yesügei and Hö’elün; both the year (1155–1167) and the birthplace are disputed.
- c. 1170Yesügei is poisoned by Tatars on the ride home; the family is abandoned by its people and reduced to gathering roots and small game.
- c. 1178Marries Börte, having been betrothed to her at eight; around the same period swears the anda pact with Jamukha and gains Toghrul of the Kerait as a patron.
- 1202–1204Defeats the Tatars (1202), Toghrul’s Kerait (1203, after an initial defeat at Qalaqaljid Sands) and the Naiman (Battle of Chakirmaut, May 1204); Jamukha is betrayed and executed.
- 1206A kurultai at the source of the Onon River proclaims him Genghis Khan; he organizes the decimal army and proclaims the Yassa law code.
- 1207–1209Raids Western Xia (1207), then launches a full invasion (1209).
- 1211Invades the Jin dynasty of northern China after a kurultai called that March.
- 1219–1221Invades the Khwarazmian Empire after the Otrar incident; Mongol forces take Bukhara, Samarkand and Gurganj.
- 1227Dies on 18 or August 25 while campaigning against Western Xia; the empire he founded at about 4 million km² in 1206 covers about 13.5 million km² at his death.
- 1229After a two-year interregnum, his son Ögedei is enthroned as Great Khan; the empire later reaches about 23.5 million km² by 1294, by Wikipedia’s account the largest contiguous empire in history.
Where the 130+ figure came from
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
Every Genghis Khan IQ figure that actually surfaces online is thin. LifeScore’s history page lists him at “130+,” with no test, source or confidence label attached, the same format the site uses across its history directory. Geniuses.club has a page titled “Genghis Khan IQ Estimate — Biography & Key Facts (2026)” that, checked in September 2026, showed only a “Full profile loading” placeholder with no score behind it, and the site’s own “Highest IQ People in History — Top 100” list does not include him at all. For how numbers like these get made in general, see where celebrity IQ numbers come from.
None of that is surprising once the dates are laid out. Genghis Khan died in 1227; Binet and Simon published the first workable intelligence test in 1905, on the other side of nearly seven centuries (see the history of intelligence testing). The sharper irony: the man himself could not have read a test question had one existed. By the documented account, Genghis Khan never learned to read or write, and the Mongols had no script of their own until he had one built for them after 1204. What survives instead is achievement — a state organized well enough to run multi-front campaigns across a continent on his own orders, the kind of record people mean by a genius IQ level, even though it is not a score.
The record needs its own warning label. The closest thing to a firsthand account, The Secret History of the Mongols, is anonymous, compiled at a date scholars still argue over (proposals run 1228 to 1264), and opens with a semi-mythical genealogy tracing the Mongols to a blue-gray wolf and a fallow doe; specialists disagree sharply on how much of it to trust. Even his death is unsettled: the Yuan-dynasty court history says a sudden fever killed him within eight days, a 2021 study in the International Journal of Infectious Diseases argues the cause was plague, and older, harder-to-verify traditions blame a fall from his horse, an arrow wound, or assassination. A record this contested cannot anchor a precise score; it can only support a wide estimate with the uncertainty stated plainly.
Placed against this site’s other great-conqueror estimates, Genghis Khan’s 130–150 sits beside Napoleon’s 130–140, Julius Caesar’s 135–155 and Alexander the Great’s 135–155, all reached the same way: from documented command and organization, not a test. The floor matches Napoleon’s for a reason neither Caesar nor Alexander shares — no writing of Genghis Khan’s own survives in any script, and no source claims he could read one. The range still reaches 150 because what he organized went further in some ways than either: a decimal army built from scratch, a written script commissioned for a language that had none, and clergy of four religions left untaxed across a state that, under his own direct command, roughly tripled from about 4 million to about 13.5 million square kilometers between 1206 and his death in 1227. An IQ around 140 is one plausible midpoint of that record; it remains, on this site’s own method, an inference from empire-building, not a recovered score.

There is no published IQ test result or IQ score for Genghis Khan, and there could not be one: he died in 1227, roughly 680 years before the Binet–Simon scale appeared in 1905. Checked in September 2026: LifeScore’s history page lists him at “130+” with no source, test or confidence label; a Geniuses.club profile titled “Genghis Khan IQ Estimate” showed only a “Full profile loading” placeholder; and Geniuses.club’s own “Highest IQ People in History — Top 100” list does not include him.
The only number that surfaces, 130+, sits at the floor of this page’s own 130–150 estimate rather than above it — unusual among this site’s ancient and medieval profiles, where circulating figures typically run well above the documented record, not level with it. But “130+” names no ceiling, so it reads less like a measurement than an admission that no one tried to bound it, and the one other profile found, on Geniuses.club, never loaded a number at all.

Genghis Khan — frequently asked
What is Genghis Khan’s IQ?
Genghis Khan’s IQ was never measured and could not have been: he died in 1227, roughly 680 years before the Binet–Simon intelligence test of 1905. The one number that actually circulates online, an open-ended “130+” with no test cited, is unverified. This site’s estimate, inferred from his documented record, is 130–150.
Was Genghis Khan a genius?
By achievement, it is hard to argue otherwise: he unified the Mongol tribes, founded an empire that had already more than tripled in size by his death in 1227, and built a functioning army, law code and writing system from a childhood with no formal schooling at all. That is reputation and documented record, not a measured score.
Did Genghis Khan take an IQ test?
No. Intelligence testing began with the Binet–Simon scale in 1905 and the term IQ was coined in 1912, close to seven centuries after Genghis Khan died in 1227. No test existed in his lifetime, and no page claiming an IQ figure for him cites one.
Was Genghis Khan illiterate?
By scholarly account, yes. Medievalists.net describes him as “an otherwise illiterate Mongol nomad,” and no writing in his own hand survives in any script. He nonetheless had a captured Uyghur scribe, Tata-tonga, adapt an alphabet for the Mongolian language and teach it to his own sons after about 1204.
How large was the Mongol Empire Genghis Khan built?
About 4 million square kilometers at its founding in 1206, growing to about 13.5 million by his death in 1227, a more than threefold increase under his own command. His successors expanded it further, to roughly 23.5 million square kilometers by 1294, by which point Wikipedia calls it the largest contiguous empire in history.
Where does the Genghis Khan IQ estimate of 130+ come from?
LifeScore’s history page lists Genghis Khan at “130+” with no test, source or confidence label shown. A Geniuses.club profile titled “Genghis Khan IQ Estimate” carries no visible score at all, and the same site’s own top-100 list of history’s highest estimated IQs does not include him.
How does Genghis Khan’s estimated IQ compare with Napoleon’s and Alexander the Great’s?
This site estimates Genghis Khan at 130–150, Napoleon at 130–140 and Alexander the Great at 135–155, all reached from documented command and organization, not a test. Genghis Khan’s floor matches Napoleon’s partly because, unlike Napoleon, Caesar or Alexander, no writing in his own hand survives at all.
How does my IQ compare with Genghis Khan?
You can find out in about fifteen minutes. The IQ Metrics assessment is 30 questions, scored on the same 100-mean scale used throughout this page, so your result and the estimate above are at least expressed in the same units — one measured, one inferred.
