Moctezuma I went down in oblivion, while his namesake, Moctezuma II, went down in infamy. The former is a terrible shame, the latter a vexing mystery.
Moctezuma I transformed the small Aztec city-state of Tenochtitlán into an empire. With his brilliant statesmanship, he created The Triple Alliance with Texcoco (ruled by his friend and ally, Nezahualcoyotl) and a lesser city-state, Tlacopan. Under his leadership, they conquered virtually all other tribes and states in central Mexico, shared the spoils, and grew incredibly wealthy.
