The document discusses the roles of native Mesoamericans in the Spanish conquest of Central America in the 16th century. It notes that the Spanish conquistadors like Cortes and Alvarado were highly dependent on native allies, who far outnumbered the Spanish forces. Native allies aided the Spanish in battles, served as guides, porters, and interpreters. Over time, as diseases reduced native populations, the Spanish grew even more reliant on the alliances and military support of local Mesoamerican groups. The document also examines legal petitions filed by native conquistadors seeking exemptions from tribute payments and arguing they should receive rewards for their roles in the conquest.
