The full story
How it was born, how it has changed and what it means.
The flag of Luxembourg has three horizontal stripes of the same size: red, white and light blue. If you put it next to that of the Netherlands, it is hard to tell them apart. The difference lies in the blue, which is lighter, and in the shape, which may be more elongated.
How it came about
The colours come from the arms of the counts of Luxembourg, from the thirteenth century: a red lion on a ground of white and blue stripes. Those three colours were taken from that coat of arms and arranged in stripes, following the fashion for tricolour flags that had begun with the French Revolution.
They were used as national colours for the first time in 1830, during the Belgian revolution, when the Luxembourgers were urged to show them. In 1845 a government circular fixed the order of the stripes: red at the top, white in the middle and blue below.
How it has changed
The design has barely changed since the nineteenth century, but it took a long time to have a law of its own. It came on 23 June 1972. In 1993 another law added the details: two possible shapes, one shorter (3:5) and one more elongated (1:2), and a well-defined light blue, precisely so as not to confuse it with the Dutch one.
What it means
The colours do not each have a symbolic meaning of their own. Everything comes from the coat of arms:
Red
the lion of the coat of arms.
White and blue
the stripes on which the lion rests.
Fun facts
The lion that competes with the flag
Luxembourgish ships and aircraft carry another flag, the Roude Léiw, “red lion”: the full coat of arms with the lion on the stripes. In competitions like the Tour de France, many fans prefer it to the tricolour.
They almost changed it
In 2006 the member of parliament Michel Wolter proposed replacing the tricolour with the red lion, which cannot be confused with any other. The proposal did not go ahead and was definitively withdrawn in 2017.
Old colours, young law
Although its colours are about eight hundred years old, the flag did not have a law defining it until 1972.
