The name may also come from the Frankish language “Lidle Franke” / “Lilde Franke”, which means “little France”. At the time, the Frankish tribes controlled the north, with the other regions like Provence, Normandy, Brittany, Aquitaine, and Alsace-Lorraine slowly becoming a part of France.

The name “Île-de-France” dates back to the medieval period, with the earliest known recording in 1387. It officially became a region (in line with the other regions of France on on 6 May 1976, when the “District of the Paris Region” was reconstituted into the Île-de-France region.

Geography and rivers

The topography of the Île-de-France is largely flat without any large mountainous areas. While the center is quite urban spreading out from Paris, the outskirts are largely rural. 

The main rivers in Île-de-France are the Seine and its tributaries known as the Marne, Oise, and Aisne rivers.

The ancient cities like Soissons and Provins on the edge of Ile-de-France were built to protect the road to the centre of the old kingdom.

History: Paris as the capital

Paris is the capital of Ile-de-France, as well as its largest city. It is the economic center of France, with the vast majority of French and international companies having their headquarters or a branch in the area.

With amazing sights like the Louvre Museum, Eiffel Tower and the Musée d’Orsay, Paris is also one of the most popular cities in the world for tourists.
