Fall of Tenochtitlan
The Siege of Tenochtitlan, the capital of the Aztec Empire, was a decisive event in the Spanish conquest of Mexico. It occurred in 1521 following extensive manipulation of local factions and exploitation of preexisting divisions by Spanish conquistador Hernán Cortés, who was aided by the support of his indigenous allies and his interpreter and companion Malinche.
Although numerous battles were fought between the Aztec Empire and the Spanish-led coalition, which was itself composed primarily of indigenous (mostly Tlaxcaltec) personnel, it was the siege of Tenochtitlan—its outcome probably largely determined by the effects of a smallpox epidemic (which devastated the Aztec population and dealt a severe blow to the Aztec leadership while leaving an immune Spanish leadership intact)—that directly led to the downfall of the Aztec civilization and marked the end of the first phase of the Spanish conquest of the Aztec Empire.
The conquest of Mexico was a critical stage in the Spanish colonization of the Americas. Ultimately, Spain conquered Mexico and thereby gained substantial access to the Pacific Ocean, which meant that the Spanish Empire could finally achieve its original oceanic goal of reaching the Asian markets.
The road to Tenochtitlan
In April 1519 Hernán Cortés, the Chief Magistrate of Santiago, Cuba, came upon the coast of Mexico at a point he called Vera Cruz with 508 soldiers, 100 sailors, and 14 small cannons. Governor Velázquez, the highest Spanish authority in the Americas, called for Cortés to lead an expedition into Mexico after reports from a few previous expeditions to Yucatán caught the interest of the Spanish in Cuba. Velázquez revoked Cortés' right to lead the expedition once he realized that Cortés intended to exceed his mandate and invade the mainland. After Cortés sailed, Velázquez sent an army led by Pánfilo de Narváez to take him into custody.
But Cortés used the same legal tactic used by Governor Velázquez when he invaded Cuba years before: he created a local government and had himself elected as the magistrate, thus (in theory) making him responsible only to the King of Spain. Cortés followed this tactic when he and his men established the city of Veracruz. An inquiry into Cortés' action was conducted in Spain in 1529 and no action was taken against him.
As he moved inland Cortés came into contact with a number of polities who resented Aztec rule; Cortés clashed with some of these polities, among them the Totonacs and Tlaxcalans. The latter surrounded his army on a hilltop for two agonizing weeks.
Moctezuma sent a group of noblemen and other emissaries to meet Cortés at Quauhtechcac. These emissaries brought golden jewelry as a gift, which greatly pleased the Spaniards. According to the Florentine Codex, Lib. 12, f.6r., Moctezuma also ordered that his messengers carry the highly symbolic penacho (headdress) of Quetzalcoatl de Tula to Cortés and place it on his person. As news about the strangers reached the capital city, Moctezuma became increasingly fearful and considered fleeing the city but resigned himself to what he considered to be the fate of his people.
Cortés continued on his march towards Tenochtitlan. Before entering the city, on November 8, 1519 Cortés and his troops prepared themselves for battle, armoring themselves and their horses, and arranging themselves in proper military rank. Four horsemen were at the lead of the procession. Behind these horsemen were five more contingents: foot soldiers with iron swords and wooden or leather shields; horsemen in cuirasses, armed with iron lances, swords, and wooden shields; crossbowmen; more horsemen; soldiers armed with arquebuses; lastly, native peoples from Tlaxcalan, Tliliuhquitepec, and Huexotzinco.
Cortés' army entered the city on the flower-covered causeway (Iztapalapa) associated with the god Quetzalcoatl. Cortés was amicably received by Moctezuma. The captive woman Malinalli Tenépal, also known as La Malinche or Doña Marina, translated from Nahuatl to Chontal Maya; the Spaniard Gerónimo de Aguilar translated from Chontal Maya to Spanish.
Moctezuma was a safety measure by the vastly outnumbered Spanish. According to all eyewitness accounts, Moctezuma initially refused to leave his palace but after a series of threats from and debates with the Spanish captains, and assurances from La Malinche, he agreed to move to the Axayáctal palace with his retinue. The first captain assigned to guard him was Pedro de Alvarado. Other Aztec lords were also detained by the Spanish. The palace was surrounded by over 100 Spanish soldiers in order to prevent any attempt at rescue.
