The flag of Belgium features three vertical stripes in black, yellow, and red, arranged from left to right. The black stripe symbolizes the strength and determination of the Belgian people, the yellow represents prosperity and wealth, and the red stands for courage and bravery. This tricolor design is derived from the coat of arms of the Duchy of Brabant and was officially adopted as the national flag in 1831 when Belgium gained independence from the Netherlands. The flag's colors are often associated with the country's rich history and its cultural identity.
