Who helped Herman Cortes conquer the Aztecs?

Hernán Cortés was aided in his conquest of the Aztecs by several key allies, including indigenous groups such as the Tlaxcalans, who were rivals of the Aztecs and provided critical military support. Additionally, he had the assistance of a Malinche (or Malintzin), an indigenous woman who served as a translator and advisor, facilitating communication and negotiations with various tribes. Cortés also benefited from his small but well-armed Spanish force and superior military technology.
