The small and densely populated nation of Belgium has played an important role in the history of Europe and other continents, especially Africa. It was a pioneering force in industry, trade, and finance during the Middle Ages, through early modern times and into the nineteenth and twentieth centuries. It introduced innovative political regimes and played a leading role in the creative arts. Yet this rich past is not widely known. This introductory history offers an accessible and rigorous overview of this small but important West-European country, synthesizing Belgium's main economic, social, political, and cultural developments from pre-Roman times until today. Today, this nation-state, born in 1830, is well-known for the rivalries between its two main language communities, and as a result is often considered a fragile or even an artificial political construct. This systematic chronological analysis of both present-day Belgium and the polities that preceded it throws fresh light on this controversial issue and demonstrates Belgium's enduring importance and influence.
