Final answer:
True, the Reconquista was a military and religious action for the Spanish. It featured long-term military campaigns aligned with religious motives to reclaim lands from Islamic rule. Additionally, forming alliances with natives was crucial to the Spanish conquest of the Aztecs.
Step-by-step explanation:
The question relates to the historic period known as the Reconquista, which was the series of campaigns by Christian states to recapture territory taken by Muslims in the Iberian Peninsula. The answer is that reconquering the Iberian Peninsula was indeed both a military and religious action for the Spanish. This period spanned several centuries and involved numerous battles and sieges, underscoring a deep intertwining of military strategy and religious fervor. The Crusade mentality was also a key component, with the Reconquista being cast as a holy struggle to reclaim Christian lands.
Additionally, in terms of the conquest of the Aztecs, recruiting native allies was indeed an important strategy for the Spanish. This critical alliance-building allowed the Spanish forces under Hernán Cortés to mount a successful campaign against the Aztec Empire, eventually leading to its downfall.
