Final answer:
Recruiting native allies was crucial for the Spanish during their conquest of the Aztecs, providing additional resources and strategic advantages, thus making the answer to the question true.
Step-by-step explanation:
The question revolves around whether recruiting native allies was significant to the Spanish during their conquest of the Aztecs. The answer is true. This historical strategy was indeed crucial in undermining the Aztec Empire. The Spanish, led by Hernán Cortés, formed alliances with various indigenous peoples who were subjugated by the Aztecs or held grievances against them.
These alliances provided Cortés with additional manpower, resources, and strategic knowledge of the local terrain and politics. Without the help of native allies, the conquest of the vast and militarily powerful Aztec Empire by a relatively small Spanish force would have been much more difficult, if not impossible.
