Φράγκους refers to the historical term used in Greece to describe the Franks, a group of Germanic tribes that played a significant role in European history during the early Middle Ages. The Franks established a powerful kingdom that eventually became the foundation for modern France. They are known for their military conquests and the spread of Christianity throughout Europe. The most notable Frankish leader was Charlemagne, who united much of Western Europe and was crowned Emperor in 800 AD. The Frankish Empire contributed to the cultural and political landscape of Europe, influencing the development of feudalism and the rise of various European nations.
