It was on 21 July 1831 that Leopold of Saxe-Coburg swore allegiance to the Belgian constitution and took the constitutional oath as the first King of Belgium.
Even though Julius Caesar mentioned the Belgae 2000 years ago, Belgium is a young nation. The independent state was created on October 4, 1830 but National day is celebrated as a commemoration of the oath of the first King.
Belgium has been without a government for well over a year now. I therefore hope that the readers of this blog do not mind a little humorist note of Belgian flags, stuck in beach buckets along with other playful things, for sale.
