Wallonia (/wɒˈloʊniə/ wol-OH-nee-ə; French: Wallonie [walɔni] ; German: Wallonien [vaˈloːni̯ən] or Wallonie [valoˈniː] ), officially the Walloon Region (French: Région wallonne [ʁeʒjɔ̃ walɔn]; German: Wallonische Region [vaˈloːnɪʃə ʁeˈɡi̯oːn]), is one of the three regions of Belgium—along with Flanders and Brussels. Covering the southern portion of the country, Wallonia is primarily French-speaking. It accounts for 55% of Belgium's territory, but only 31% of its population. The Walloon Region and the French Community of Belgium, which is the political entity responsible for matters related mainly to culture and education, are independent concepts, because the French Community of Belgium encompasses both Wallonia and the bilingual Brussels-Capital Region but not the German-speaking Community of Belgium, which administers nine municipalities in Eastern Wallonia.
During the Industrial Revolution, Wallonia was second only to the United Kingdom in industrialization, capitalizing on its extensive deposits of coal and iron. This brought the region wealth, and from the beginning of the 19th to the middle of the 20th century, Wallonia was the more prosperous half of Belgium. Since World War II, the importance of heavy industry has greatly diminished, and the Flemish Region has exceeded Wallonia in wealth as Wallonia has declined economically. Wallonia now suffers from high unemployment and has a significantly lower GDP per capita than Flanders. The economic inequalities and linguistic divide between the two are major sources of political conflicts in Belgium and a major factor in Flemish separatism.
