When did the Aztec civilization establish its capital, Tenochtitlan?

The Aztec civilization established its capital, Tenochtitlan, in 1325 CE. This date signifies the founding of one of the most influential Mesoamerican cities, which later became a major center for trade, culture, and politics in the region. Tenochtitlan was built on an island in Lake Texcoco, and its strategic location allowed the Aztecs to control trade routes and resources, contributing significantly to their power and prosperity. The establishment of the city at this time marked the beginning of the Aztec ascendancy in the Valley of Mexico. This key moment in history is crucial for understanding the development of the Aztec Empire and its eventual expansion throughout Mesoamerica.
