On the night of June 30 - July 1, 1520, the Spanish conquistadors occupying Tenochtitlan decided to escape from the city, as they had been under heavy attack for several days. The Spanish tried to escape under cover of darkness, but they were spotted by locals, who rallied the Mexica warriors to attack. Although some of the Spaniards escaped, including expedition leader Hernan Cortes, many were slain by the angry natives, and many of the golden treasures of Montezuma were lost. The Spanish referred to the escape as "La Noche Triste," or "the Night of Sorrows."
The Conquest of the Aztecs
In 1519, conquistador Hernan Cortes landed near present-day Veracruz with about 600 men and began slowly making his way to the magnificent capital city of the Mexica (Aztec) Empire, Tenochtitlan. On his way into the Mexican heartland, Cortes learned that the Mexica controlled many vassal states, most of which were unhappy about the Mexica's tyrannical rule. Cortes also first defeated, then befriended the warlike Tlaxcalans, who would provide invaluable assistance in his conquest. On November 8, 1519, Cortes and his men entered Tenochtitlan. Before long, they took Emperor Montezuma captive, resulting in a tense stand-off with the remaining native leaders who wanted the Spaniards out.
