Oxford University Is Older Than the Aztec Empire
Teaching was already taking place in Oxford in the late 11th century, more than 200 years before Tenochtitlan was founded and over 300 years before the Aztec Empire emerged. Here are the dates and what counts as a founding in each case.

It feels like the natural order has been flipped: a university that still operates, with students sitting exams today, is older than an empire we usually associate with the distant past. But the dates are clear. Teaching existed in Oxford by 1096. Tenochtitlan, the Aztec capital, was founded around 1325, and the empire itself only took shape in 1428. Depending on the yardstick, Oxford has a head start of 200 to more than 300 years.
When Oxford began
Oxford has no official founding date. The university itself says there is no clear starting point, but that teaching existed there in some form in 1096. Like many medieval universities, it was not created by decree: it grew gradually from masters who taught and students who gathered around them.
The big boost came in 1167, when King Henry II banned English students from attending the University of Paris during his quarrel with Thomas Becket. Many returned home and Oxford grew quickly. From then on, institutional milestones pile up: the head of the university held the title of chancellor from at least 1214, and Henry III granted a royal charter in 1248. The oldest colleges, University, Balliol and Merton, were established between 1249 and 1264.
A related twist: in 1209, after violent clashes between townspeople and students, a group of scholars left Oxford and settled in Cambridge, giving rise to England's other great university. Oxford is regarded as the oldest university in the English-speaking world.
When the Aztec Empire emerged
The Mexica, the people we later came to call the Aztecs, were originally nomadic. According to their tradition, they migrated from a place called Aztlan, whose location has never been identified, before settling on islands in Lake Texcoco in the Valley of Mexico. There they founded Tenochtitlan around 1325. That traditional date comes from Indigenous and colonial sources and should be read as approximate.
Founding a city, however, is not the same as building an empire. For decades the Mexica were subordinate to the Tepanecs of Azcapotzalco. Only in 1428 did Tenochtitlan join Texcoco and Tlacopan in the Triple Alliance, defeat Azcapotzalco and begin the expansion that produced what we now call the Aztec Empire. That empire fell in 1521, when Spanish forces and their Indigenous allies took Tenochtitlan.
Even the name Aztec came later: the term was popularized in the early 19th century by the naturalist Alexander von Humboldt, drawing on the name Aztlan.
A side-by-side timeline
| Year | Oxford | Mexica and Aztecs |
|---|---|---|
| 1096 | Evidence of teaching in Oxford | The Mexica had not yet settled in the Valley of Mexico |
| 1167 | Ban on studying in Paris speeds up growth | - |
| 1209 | Scholars leave Oxford and found Cambridge | - |
| 1248 | Royal charter from Henry III | - |
| 1249 to 1264 | First colleges founded | - |
| c. 1325 | University already well established | Tenochtitlan founded |
| 1428 | - | Triple Alliance: the empire begins |
| 1521 | - | Fall of Tenochtitlan |
What the comparison really shows
This fact does not mean the Aztecs were backward or that their history begins in 1325. Complex societies occupied the Valley of Mexico long before that, and cities such as Teotihuacan are older than Oxford and many European capitals. What the comparison really shows is something else:
- The Aztec Empire was relatively short-lived: it lasted less than a century, from 1428 to 1521.
- Institutions can outlast states; Oxford survived wars, religious reformations and changes of dynasty.
- Founding dates depend on the yardstick: a first lecture, a first official document, the founding of a city or the forming of a political alliance.
Bottom line: whichever yardstick you use, Oxford comes first. Counting from the start of teaching (1096), it is about 230 years older than Tenochtitlan and more than 330 years older than the empire. Even using a more formal milestone such as the 1248 royal charter, Oxford still predates the Aztec capital by nearly 80 years. It is a useful reminder that when comparing civilizations, it pays to ask: the beginning of what, exactly?
