Who Founded France?
France was established over time, from the period of Charlemagne to the Hundred Years' War. The territory ruled by the Valois dynasty after the Hundred Years' War in the 15th century resembles modern France, according to Nations Online.
After the death of Frankish King Charlemagne, often considered the founder of Europe, the Holy Roman Empire was divided among his three sons, into three territories that roughly would become France, Germany and Italy. These territories were ruled by feudal lords. Capetian rulers of the area surrounding Paris called the region the île-de-France. After France's victory over England in the Hundred Years' War (1337-1453), the Valois dynasty gained rule over areas once disputed by England. Modern France most resembles this territory, after Burgundy and Brittany were added.
