text: An anthem,  (The Walloons' Song), written by Theophile Bovy in 1900 and composed by Louis Hillier in 1901, was also adopted. On September 21, 1913, the "national" feast day of Wallonia took place for the first time in Verviers, commemorating the participation of Walloons during the Belgian Revolution of 1830. It is held annually on the third Sunday of September. The Assembly also chose a motto for Wallonia, "Walloon Forever" (), and a cry, "Liberty" (). In 1998, the Walloon Parliament made all these symbols official except the motto and the cry.
  Religion
  The population of Wallonia is predominantly of Christian heritage. In 2016, 68% of residents of Wallonia declared themselves to be Roman Catholic (21% were practising Catholics and 47% were non-practising), 3% were Muslim, 3% were Protestant Christian, 1% were of other religions and 25% were non-religious.
  Languages
  Official languages
  French is the official language of Wallonia and by far the most used; in the East Cantons, German is also official. The German-speaking Community of Belgium accounts for about 2% of the region's population. Belgian French, which is also spoken in the Brussels-Capital Region, is similar to that spoken in France, with slight differences in pronunciation and some vocabulary differences, notably the use of the words septante (70) and nonante (90), as opposed to soixante-dix and quatre-vingt-dix in France.
  There are noticeable Walloon accents, with the accent from Liège and its surroundings being perhaps the most striking. Other regions of Wallonia also have characteristic accents, often linked to the regional language.
