Final answer:
The Reconquista was a campaign by the Spanish Christian kingdoms to recapture territory from the Muslim Moors, carrying significant religious motives alongside its military operations; thus, it is true that it was both military and religious.
Step-by-step explanation:
The Reconquista, undertaken by the Spanish, was indeed both a military and religious effort. This campaign aimed at taking back the Iberian Peninsula from the Moors, who were Muslim. There was a strong religious motive as the Christian kingdoms of Spain sought to re-Christianize the region, which had been under Islamic rule for several centuries.
The Reconquista spanned from the Battle of Covadonga in 722 AD, which was the first victory by Christian military forces in Iberia, to the fall of Granada in 1492. It marked the end of Muslim rule in the peninsula. As such, claiming that the Reconquista had both military and religious aspects is true.
