Final answer:
The Reconquista was both a military and a religious effort by the Spanish to reclaim the Iberian Peninsula from Muslim control, making the statement true.
Step-by-step explanation:
The statement that for the Spanish, reconquering the Iberian Peninsula was a military and religious action is true. This historical period, known as the Reconquista, lasted from the 8th century until 1492. It involved the Christian kingdoms in the north of the peninsula fighting to retake land from the Muslim states that had controlled much of the Iberian Peninsula since the early 8th century. The Reconquista is characterized by both military campaigns and religious motivations, as the Christian forces sought to spread Christianity and diminish Muslim rule.
