The statement that accurately describes the fall of the Aztec empire is: "The Aztec Empire in modern-day Mexico was conquered by Hernan Cortes and his Spanish soldiers, Who were called conquistadores." Option C is correct.
The final victory of the Spanish campaign against the Aztec Empire took place on August 13, 1521, when a coalition army of Spanish forces along with native Tlaxcalan warriors directed by Cortés and Xicotencatl the Younger captured the emperor Cuauhtemoc and the capital of the Aztec Empire, Tenochtitlan.
