Captivity of Moctezuma II
Soon after arriving in Tenochtitlan, Cortés seized Moctezuma and, through him, became indirect ruler of the Aztec Empire. This situation lasted some months until April 1520, when an expedition arrived from Cuba with orders to arrest Cortés (its arrival would also unintentionally lead to millions of indigenous deaths by introducing smallpox to Mexico). Cortés raced to the coast and dealt with this new challenge, but during his absence the acting Spanish governor massacred large numbers of Aztecs while they were celebrating a religious festival, destroying Aztec–Spanish relations.
