Conquistador y Pestilencia: The First New World Pandemic and the Fall of the Great Indian Empires
T HE MOST SENSATIONAL military conquests in all history are probably those of the Spanish conquistadores over the Aztec and Inean empires. Cortes and Pizarro toppled the highest civilizations of the New World in a few months each. A few hundred Spaniards defeated populations containing thousands of dedicated warriors, armed with a wide assembly of weapons from the stone and early metal ages. Societies which had created huge empires through generations of fierce fighting collapsed at the touch of the Castilian. After four hundred years the Spanish feat still seems incredible.

The arrival of Columbus in the New World brought about one of the greatest population disasters in history. After the Spanish conquest an Indian of Yucatan wrote of his people in the happier days before the advent of the Spaniard :1
