Flag of Belgium
Belgium is a small but densely populated country in Western Europe that serves as the de facto capital of the European Union, hosting the EU's major institutions in Brussels. The country is divided into three linguistic communities — Dutch-speaking Flanders, French-speaking Wallonia, and a small German-speaking area — giving it a complex federal structure. Belgium is celebrated globally for its chocolate, beer, waffles, and its rich tradition of comic art.

What the flag of Belgium means
Belgium's colours come from the arms of the Duchy of Brabant: a golden lion with red claws and tongue on a black field. They were used in the Brabant Revolution of 1789 and again in the 1830 revolution that won independence from the Netherlands. The vertical layout, adopted in 1831, was probably inspired by the French tricolour. The official 13:15 proportions are unusual and rarely followed; most Belgian flags are made at 2:3.
How to recognise it
Vertical black-yellow-red stripes. Germany's similar colours are horizontal.

Flag history of Belgium
Every flag that has flown over Belgium, from today back through time.
1831–present
Kingdom of Belgium
Belgium's vertical black-yellow-red tricolor was adopted at independence in 1831. The colours derive from the ducal arms of Brabant — a golden lion on black — combined with red from the arms of Hainaut. It's unusually tall and narrow compared to most flags (13:15 ratio), and the black stripe is on the hoist side — the only national flag with black in that position.
1815–1830
Under the Kingdom of the Netherlands
After Napoleon's defeat, the Congress of Vienna merged the Austrian Netherlands (roughly modern Belgium) and the Dutch Republic into the United Kingdom of the Netherlands under King William I. The Dutch orange-white-blue flag (displayed as red-white-blue) flew over Belgian territory. The forced union proved deeply unpopular — language, religion, and economic policies all divided north from south, leading to the Belgian Revolution of 1830.
1789–1790
Brabantine Revolution
The 1789 Brabantine Revolution against Austrian rule briefly created the United Belgian States. The revolutionary flag took the black, yellow, and red from the coat of arms of the Duchy of Brabant and arranged them horizontally (black on top, as in the Brabant arms). After Belgium's eventual independence in 1830, the revolutionary tradition was honoured but the stripes were turned vertical — creating today's distinctive flag.
