Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe. The country is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the south, and the North Sea to the west. It covers an area of 30,689 km2 (11,849 sq mi) and has a population of more than 11.7 million. With 383/km2 (990/sq mi), Belgium's population density ranks 22nd in the world and 6th in Europe. Belgium is part of an area known as the Low Countries, historically a somewhat larger region than the Benelux group of states, as it also included parts of northern France. The capital and largest metropolitan region is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven.

Flanders is the Dutch-speaking northern portion of Belgium and one of the communities, regions and language areas of Belgium. However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Fleming, while the corresponding adjective is Flemish, which can also refer to the collective of Dutch dialects spoken in that area, or more generally the Belgian variant of Standard Dutch.

Walloons are a Gallo-Romance ethnic group native to Wallonia and the immediate adjacent regions of Flanders, France, Germany, Luxembourg and the Netherlands. Walloons primarily speak langues d'oïl such as Belgian French, Picard and Walloon. Walloons are primarily Roman Catholic, with a historical minority of Protestantism which dates back to the Reformation era.

Wallonia, officially the Walloon Region, 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 a third 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.

The Kingdom of Belgium is divided into three regions. Two of these regions, Flanders and Wallonia, are each subdivided into five provinces. The third region, Brussels, does not belong to any province, nor is it subdivided into provinces. Instead, it has amalgamated both regional and provincial functions into a single "Capital Region" administration.

The Flemish Movement is an umbrella term which encompasses various political groups in the Belgian region of Flanders and, less commonly, in French Flanders. Ideologically, it encompasses groups which have sought to promote Flemish culture and the Dutch language as well as those seeking greater political autonomy for Flanders within Belgium. It also encompasses nationalists who seek the secession of Flanders from Belgium, either through outright independence or (re)unification with the Netherlands.

In Belgium, the French Community refers to one of the three constituent constitutional linguistic communities. Since 2011, the French Community has used the name Wallonia-Brussels Federation, which is controversial because its name in the Belgian Constitution has not changed and because it is seen as a political statement. The name "French Community" refers to Francophone Belgians, and not to French people residing in Belgium. As such, the French Community of Belgium is sometimes rendered in English as "the French-speaking Community of Belgium" for clarity, in analogy to the German-speaking Community of Belgium.

The Flemish Region, usually simply referred to as Flanders, is one of the three regions of Belgium—alongside the Walloon Region and the Brussels-Capital Region. Covering the northern portion of the country, the Flemish Region is primarily Dutch-speaking. With an area of 13,626 km2 (5,261 sq mi), it accounts for only 45% of Belgium's territory, but 58% of its population. It is one of the most densely populated regions of Europe with around 500/km2 (1,300/sq mi).

Lodewijk De Raet was a Flemish economist and politician. He played an important role in the Flemish movement. He was co-founder of the Vlaamsche volkspartij (1892), and was a proponent of the use of Dutch instead of French at the University of Ghent in Flanders.
