The Franks were a western European people during the Roman Empire and Early Middle Ages. They began as a Germanic people who lived near the Lower Rhine, on the northern continental frontier of the empire. They subsequently expanded their power and influence during the Middle Ages, until much of the population of western Europe, particularly in and near France, were commonly described as Franks, for example in the context of their joint efforts during the Crusades starting in the 11th century. This expansion came about because the romanized Frankish dynasties based within the collapsing Western Roman Empire first became the rulers of the whole region between the rivers Loire and Rhine, and then subsequently imposed power over many other post-Roman kingdoms both inside and outside the old empire.

France, officially the French Republic, is a country located primarily in Western Europe. It also includes overseas regions and territories in the Americas and the Atlantic, Pacific and Indian oceans, giving it one of the largest discontiguous exclusive economic zones in the world. Metropolitan France shares borders with Belgium and Luxembourg to the north, Germany to the north east, Switzerland to the east, Italy and Monaco to the south east, Andorra and Spain to the south, and a maritime border with the United Kingdom to the north west. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea. Its overseas territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean. Its eighteen integral regions span a combined area of 643,801 km2 (248,573 sq mi) and have a total population of 68.4 million as of January 2024.
