The flag of Luxembourg consists of three horizontal stripes: red at the top, white in the middle, and a light blue at the bottom. The red symbolizes the people and their commitment to the country’s liberty and freedom. The white represents the peace and unity of Luxembourg. The light blue reflects the country’s devotion to justice and prosperity. The flag's design is based on the historical banner of the House of Nassau, and it was officially adopted in 1845, although it had been used in various forms since the early 19th century. The lighter shade of blue used in the current flag differentiates it from the flag of the Netherlands, which has similar colors.
