In 1519 Spanish explorer and Conquistador Hernan Cortez landed on the shore of eastern Mexico with 11 ships and over 500 soldiers. When they arrived at the temple at Tenochtitlán, they witnessed a priest rip out a living man’s heart, raise it in the air, and toss his corpse down the temple stairs. This one event set in motion a series of cascading events that would forever alter the course of world history, and create controversies for Cortez, Spain and the Catholic Church ever since.
