Answer
Brief Explanations:
The Carolingians had notable military - related achievements. One of their founders, Charles Martel, defeated a Muslim invasion at the Battle of Tours in 732. This victory halted the Muslim expansion into Western Europe. The other options are incorrect as it was not about convincing all Europeans to convert to Christianity, nor about winning the title of first warrior - king of France in the way described, and not about making Spain the most powerful country in Europe.
Answer:
He defeated a Muslim invasion from Spain.
