History of Rennes

Rennes, France, is the administrative capital of the French department of Ille-et-Vilaine. Before the French Revolution, prior to the integration of the Duchy of Brittany into the Kingdom of France, Rennes was the capital of the duchy, with the other historical capitals of Brittany's Ducal period being Nantes and Vannes. It has a long history due to its location at the confluence of two rivers and its proximity to the bordering regions from which arose various challenges to the borders of Brittany.
