What forced caused the decline of Muslim rule and helped bring about the reconquista?

The decline of Muslim rule in the Iberian Peninsula was primarily influenced by internal divisions among the Muslim states, particularly the fragmentation of the Almohad and Almoravid empires, which weakened their central authority and military strength. Additionally, the rise of Christian kingdoms, fueled by a growing sense of identity and purpose, led to coordinated military campaigns against Muslim territories. Key battles, such as the Battle of Las Navas de Tolosa in 1212, significantly shifted the balance of power, paving the way for the Reconquista to reclaim the peninsula for Christianity. This long process culminated in 1492 with the fall of Granada, the last Muslim stronghold.
