Brussels, officially the Brussels Region or Brussels-Capital Region, is the capital of Belgium and the de facto capital of the European Union (EU). It is also the largest urban area in Belgium, comprising 19 municipalities, including the municipality of the City of Brussels, which is the de jure capital of Belgium, in addition to the seat of the French Community of Belgium and of the Flemish Community. Brussels has grown from a 10th-century fortress town founded by a descendant of Charlemagne to more than one million inhabitants. The city has a population of 1.1 million and the metropolitan area has a population of over 1.8 million, both making it the largest in Belgium. Since the end of the Second World War, Brussels has been a main centre for international politics.
