Answer: which the celebration of the Feast of Toxcatl ended in a massacre of Aztec elites. While Hernán Cortés was in Tenochtitlan, he heard about other Spaniards arriving on the coast – Pánfilo de Narváez had come from Cuba with orders to arrest him – and Cortés was forced to leave the city to fight them. During his absence, Moctezuma asked deputy governor Pedro de Alvarado for permission to celebrate Toxcatl (an Aztec festivity in honor of Tezcatlipoca, one of their main gods). But after the festivities had started, Alvarado interrupted the celebration, killing all the warriors and noblemen who were celebrating inside the Great Temple. The few who managed to escape the massacre by climbing over the walls informed the community of the Spaniards' atrocity.
