The emperors of the Aztec empire were:
  1. Acamapichtli 1372-1391
  2. Huitzilihuitl 1391-1416
  3. Chimalpopoca 1416-1427
  4. Itzcoatl 1427-1440
  5. Moteuczoma I 1440-1468
  6. Axayacatl 1468-1481
  7. Tizoc 1481-1486
  8. Ahuitzotl 1486-1502
  9. Moteuczoma II 1502-1520
  10. Cuitlahuac 1520
  11. Cuauhtemoc 1520-1521
The perils of scholarship. No doubt in school we were all taught that Montezuma's real name was Moctezuma; now we find it was actually Moteuczoma.

This list gives the foundation of the kingdom as 1372, but says dates before the reign of Axayacatl are approximate and depend on matching the cycle calendar. So this is not inconsistent with Cyt's date of 1375 in the previous write-up.
