Who helped him conquer the Aztecs?

Hernán Cortés was aided in his conquest of the Aztecs by several key allies, most notably the Tlaxcalans, a rival indigenous group who opposed Aztec rule. They provided crucial military support and knowledge of the region. Additionally, Cortés benefited from the translation services of La Malinche, a Nahua woman who acted as his interpreter and advisor, facilitating communication and alliances with other indigenous peoples.
