The correct answer is France, Germany, and Italy. Charlemagne, also known as Charles the Great, was the King of the Franks and later became the first Holy Roman Emperor. He expanded the Frankish kingdom through military campaigns and diplomacy, ultimately establishing a vast empire that encompassed modern-day France, Germany, and Italy. Greece and Turkey were not included in Charlemagne's conquests, and England, Ireland, Wales, Spain, and Portugal were not part of his empire either.
