The name 'Belgium' is derived from Gallia Belgica, a Roman province in the northernmost part of Gaul that was inhabited by the Belgae, a mix of Celtic and Germanic peoples. Historically, Belgium, the Netherlands and Luxembourg were known as the Low Countries, which used to cover a somewhat larger area than the current Benelux group of states. From the end of the Middle Ages until the 17th century, it was a prosperous centre of commerce and culture. From the 16th century until the Belgian revolution in 1830, many battles between European powers were fought in the area of Belgium, causing it to be dubbed "the cockpit of Europe"—a reputation strengthened by both World Wars.
