The Aztec people were certain ethnic groups of Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to 16th centuries. The Nahuatl words aztecatl and aztecah mean "people from Aztlan", a mythological place for the Nahuatl-speaking culture of the time.
The entire city of Tenochtitlan was divided into five quadrants, if you count the center one. Canals divided the city in the four cardinal directions. The central plaza was not the only administrative and religious center in Tenochtitlan. In the center of each of the four surrounding quadrants there was also a central plaza(Smith 197).
The Aztecs were so disciplined, so skilled in the arts of war, that their realm appeared invincible.
Nahuatl was the language spoken by the various Nahua tribes, an indigenous group in central Mexico in the years prior to the Spanish Conquest in the sixteenth century...The most famous of the Nahuatl speaking peoples were the Aztecs[.]
At the height of their power, Aztec armies and cities contained hundreds of thousands of people, but it took the Spanish only three years, from 1519 to 1521, to almost completely destroy the mighty Empire.
Aided by the alliances he [Cortés] formed with other indigenous groups hostile to the Aztecs, Cortés sieged Tenochtitlan and proceeded to sack the city, decimating its population through starvation, massacre and imported disease. In just a few years, smallpox had reduced the indigenous population by 90%.
Moctezuma was regarded as a semi-divine figure by his subjects and charged with the task of interceding with the gods. As a battle-hardened general he was appointed supreme military commander and headed the two most prestigious divisions: the Eagle and the Jaguar warriors.
In 1428, under their leader Itzcoatl, the Aztecs formed a three-way alliance with the Texcocans and the Tacubans to defeat their most powerful rivals for influence in the region, the Tepanec, and conquer their capital of Azcapotzalco.
A nomadic culture, the Aztecs eventually settled on several small islands in Lake Texcoco where, in 1325, they founded the town of Tenochtitlan, modern-day Mexico City.
The Aztec Empire was peopled by a group that was once nomadic, the Mexicas. Their chroniclers told them that after their long journey from Aztlán, they found themselves to be outcasts, until they found the sign sent to them by their god Huitzilopochtli, and began to build their city.
The exact origins of the Aztec people are uncertain, but they are believed to have begun as a northern tribe of hunter-gatherers whose name came from that of their homeland, Aztlan (or "White Land").
