Answer 1

The Tlaxcalan rulers saw the Spanish (i.e., Cortes) as a possible ally against the Aztecs, and Cortes won over the leadership and was careful about what areas he claimed. He even convinced many elders and leaders to convert to Catholicism. An exchange of gifts was made, and an alliance was formed.

Answer 2

Some Native Americans were willing to form alliances with European settlers because they saw it as an opportunity to gain protection against rival Native American tribes, acquire trade goods such as guns and metal tools, and potentially gain access to new land and resources. Additionally, some Native Americans believed that forming alliances with Europeans would help them resist colonization and maintain their autonomy.
