Francia is a historical region in Europe, primarily known as the heartland of the ancient Franks, a Germanic tribe. It played a significant role in the formation of modern France and Germany. Francia was divided into several kingdoms during the early Middle Ages, with notable rulers like Charlemagne, who expanded its territory and established the Carolingian Empire. The term "Francia" can also refer to the broader cultural and political influence of the Frankish people. This influence shaped the development of medieval European society, including the spread of Christianity and the establishment of feudalism. Today, Francia is often studied in the context of European history and its impact on contemporary nations.
