On 7 February 1831, the Belgian Constitution was proclaimed and the separation from the Dutch was a fact.
But all was not so calm and peaceful.
“Though the new-born country had unifying elements, such as the Catholic religion, a French-speaking bourgeoisie and common economic interests opposed to the Dutch economic ones, the building of a unitary Belgian state posed some serious problems. The language question emerged in 1840. Despite the fact that the free use of languages was enshrined in the Constitution, only French was used in the administration, education and justice systems.” ~Source
So in 1970 we created Région Wallonne. (Les Allemands et les Flamands sont comme une nuisance…heh heh)
Today we are so proud to have our own country…excuse me, region of Belgium.
