Moctezuma I ruled as the huey tlatoani of the Aztec Empire from 1440 to 1469. He was known for expanding the Aztec Empire through military conquests. For instance, he strengthened Tenochtitlán’s dominance in the Valley of Mwxico by increasing tribute collection, enforcing strict laws, and overseeing major temple constructions, including the expansion of the Templo Mayor.

EARLY HISTORY OF THE AZTEC

Following the Aztec’s founding and construction of Tenochtitlan in the Valley of Mexico in 1325 AD, they quickly established their authority across the other societies in the valley.  Historians refer to this time period as the Aztec Empire, since the Aztec were constantly expanding throughout central Mexico.  As well, for the two centuries that followed the initial construction of Tenochtitlan, the Aztec were ruled over by a series of leaders referred to as Huey Tlatoani.  In the Aztec language of Nahuatl this translates to ‘Great Speaker’.  Each huey tlatoani ruled in different ways but they all oversaw the expansion of both Tenochtitlan and the Aztec Empire until the arrival of the Spanish conquistadors in 1519.
