Territorial formation of France

This article describes the process by which the territorial extent of metropolitan France came to be as it is since 1947. The territory of the French State is spread throughout the world. Metropolitan France is that part which is in Europe.

Occidental France, which arose from the Treaty of Verdun of 843, remained stable for many years. The first kings, the Capetians, were too much occupied with imposing their authority in their own realm to be expansionist. They deftly exploited dissent among their turbulent vassals, applying pressure on them and on the Church and towns. The great conflicts with the kings of England were important occasions for asserting royal power. The 13th century re-annexations of Normandy and of Languedoc to the French kingdom were two important stages in the unification of the kingdom.

France soon lost the County of Barcelona (Catalonia), from the end of the 9th century. The crossing beyond Rhone, which for a long time remained the frontier, did not begin until the 14th century, with the purchase of the Dauphiné. Louis XI regained his inheritance of the two most powerful prerogatives granted to cadet branches of the dynasty: Burgundy and Anjou including Provence in the Holy Roman Empire (1481–1482).

The marriage of Anne of Brittany first with Charles VIII then with Louis XII led finally to the effective annexation in 1532, of her duchy which was already within the ambit of the French Kingdom but which had hitherto firmly maintained its distinct existence.
