by the Tlaxcalan general Tlahuicole invaded the Purépecha Empire once again. The Aztec army failed to take any territory and was mostly restricted to raiding. The Purépecha defeated them and the army withdrew. Moctezuma II instituted more imperial reforms. The death of Nezahualcoyotl caused the Mexica Emperors to become the rulers of the alliance. Moctezuma II used his reign to attempt to consolidate power more closely with the Mexica Emperor. He removed many of Ahuitzotl's advisors and had several of them executed. He also abolished the class, destroying the chance for commoners to advance to the nobility. His reform efforts were cut short by the Spanish Conquest in 1519. Spanish conquest The Spanish expedition leader Hernán Cortés landed in Yucatán in 1519 with approximately 630 men (most armed with only a sword and shield). Cortés had actually been removed as the expedition's commander by the governor of Cuba Diego Velásquez but had stolen the boats and left without permission. At the island of Cozumel, Cortés encountered a shipwrecked Spaniard named Gerónimo de Aguilar who joined the expedition and translated between Spanish and Mayan. The expedition then sailed west to Campeche, where, after a brief battle with the local army, Cortés was able to negotiate peace through his interpreter Aguilar. The King of Campeche gave Cortés a second translator, a bilingual Nahua-Maya slave woman named La Malinche (she was known also as Malinalli [maliˈnalːi], Malintzin [maˈlintsin] or Doña Marina [ˈdoɲa maˈɾina]). Aguilar translated from Spanish to Mayan, and La Malinche translated from Mayan to Nahuatl. Malinche became Cortés' translator for both language and culture once she learned Spanish, and she was a key figure in interactions with Nahua rulers. Cortés then sailed from Campeche to Cempoala, a tributary province of the Aztec Triple Alliance. Nearby, he founded the town of Veracruz where he met with ambassadors from the reigning Mexica emperor Motecuzoma II. When the ambassadors returned to Tenochtitlan, Cortés went to Cempoala to meet with the local Totonac leaders. The Totonac ruler told Cortés of his various grievances against the Mexica, and Cortés convinced the Totonacs to imprison an imperial tribute collector. Cortés subsequently released the tribute collector after persuading him that the move was entirely the Totonac's idea and that he had no knowledge of it. The Totonacs provided Cortés with 20 companies of soldiers for his march to Tlaxcala, having effectively declared war on the Aztecs. At this
