The Aztec empire was an informal or hegemonic empire because it did not exert supreme authority over the conquered territories; it was satisfied with the payment of tributes from them. It was a discontinuous empire because not all dominated territories were connected; for example, the southern peripheral zones of Xoconochco were not in direct contact with the center. The hegemonic nature of the Aztec empire was demonstrated by their restoration of local rulers to their former position after their city-state was conquered. The Aztec did not interfere in local affairs, as long as the tributes were paid.
