The Aztecs were advanced fr their time but not as advanced as the Spanish were so in 1521 the Aztecs got taken over by the Spanish. Their commander was Hernan Cortes. Sadly the Aztecs werent as advanced as the spanish were. The spanish had heavy and durable armor,cannons and guns to attack and defend with.
