Cuauhtémoc, also known as Cuauhtemotzín, Guatimozín, or Guatémoc, was the Aztec ruler (tlatoani) of Tenochtitlan from 1520 to 1521, and the last Aztec Emperor. The name Cuauhtemōc means "one who has descended like an eagle", and is commonly rendered in English as "Descending Eagle", as in the moment when an eagle folds its wings and plummets down to strike its prey; the name thus implies aggressiveness and determination.
