Final answer:
The advance of the Moors in Europe was stopped at the Battle of Tours in 732 C.E. The larger process of pushing back Islamic influence in the Iberian Peninsula, known as the Reconquista, was completed in 1492 with the capture of Granada.
Step-by-step explanation:
Stopping the Advance of the Moors in Europe
The advance of the Moors in Europe was halted in a couple of significant battles, most notably the Battle of Tours. In 732 C.E., Charles Martel, a leader known as 'The Hammer', led Christian forces to victory against the Moors at the Battle of Tours, also known as the Battle of Poitiers, in what is now modern France. This battle marked a decisive end to the Muslim expansion into Western Europe.
Moreover, the Islamic presence in Europe was eventually pushed back to the Iberian Peninsula. The process known as the Reconquista slowly reclaimed land from the Muslims over several centuries. The Reconquista culminated in 1492 with the surrender of Granada, effectively ending seven centuries of Muslim control in the Iberian Peninsula.
While the Moors had significant control and influence, particularly in Spain where cities like Córdoba flourished in trade and learning, the military advance into the rest of Europe was effectively halted by Christian forces. Nevertheless, the Islamic architectural and cultural heritage continued to have a lasting impact on the Iberian region long after the Reconquista.
