When the Spanish Invaded Mesoamerica, They Found

When the Spanish invaded Mesoamerica, they found:

A) a decentralized Maya with a scattered population no longer building great monuments
B) the Maya civilization at its peak, though the lack of a centralized Maya military led to their easy defeat by the Spanish conquistadors
C) the Maya locked in a bloody war with the Aztecs, making both of these Mesoamerican civilizations an easy target for the Spanish military
D) nothing but ruins; the Maya people were gone, creating one of the greatest archaeological mysteries facing modern scholars
