Flemish people or Flemings (Vlamingen ˈvlaːmɪŋə(n)) are an ethnic group native to Flanders, Belgium, who speak Flemish Dutch. Flemish people make up the majority of Belgians, at about 60%.
"Flemish" was historically a geographical term, as all inhabitants of the medieval County of Flanders in modern-day Belgium, France, and the Netherlands were referred to as "Flemings", irrespective of their ethnicity or language. The contemporary region of Flanders comprises a part of this historical county, as well as parts of the medieval duchy of Brabant and the medieval county of Loon, where the modern national identity and culture gradually formed.
The sense of "Flemish" identity increased significantly after the Belgian Revolution. Prior to this, the term "Vlamingen" in the Dutch language was in first place used for the inhabitants of the former County of Flanders. Flemish, however, had been used since the 14th century to refer to the language and dialects of both the peoples of Flanders and the Duchy of Brabant. The modern Belgian province of Limburg was not part of the Treaty of London that followed the Belgian Revolution, and only came to be considered "Flemish" in the 19th century.
In 1830, the southern provinces of the United Netherlands proclaimed their independence. French-dialect speaking population, as well as the administration and elites, feared the loss of their status and autonomy under Dutch rule while the rapid industrialization in the south highlighted economic differences between the two. Under French rule (1794–1815), French was enforced as the only official language in public life, resulting in a Francization of the elites and, to a lesser extent, the middle classes. The Dutch king allowed the use of both Dutch and French dialects as administrative languages in the Flemish provinces. He also enacted laws to reestablish Dutch in schools. The language policy was not the only cause of the secession; the Roman Catholic majority viewed the sovereign, the Protestant William I, with suspicion and were heavily stirred by the Roman Catholic Church which suspected William of wanting to enforce Protestantism.
