# Belgian Revolution

> Belgian rebels successfully seceded from the United Kingdom of the Netherlands, establishing an independent constitutional monarchy in Western Europe.

In 1830, the southern provinces of the United Kingdom of the Netherlands—primarily present-day Belgium—rose up against Dutch rule and declared independence. Led by a coalition of liberals, Catholics, and nationalists, the revolt succeeded in establishing the Kingdom of Belgium as a sovereign state, redrawing the map of Western Europe and settling a dispute that had festered since the 1815 Congress of Vienna.
