The Flemish Movement (Dutch: Vlaamse Beweging, pronounced [ˈvlaːmsə bəˈʋeːɣɪŋ]) 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 unification with the Netherlands.
In the 19th century, the Flemish Movement emerged around a form of cultural patriotism which celebrated the regional traditions and history of Flanders and sought equal status for Dutch in the Belgian nation-state, often under the auspices of the Catholic Church. Although gaining a number of its initial objectives, it became increasingly radical in the aftermath of World War I. Inspired by authoritarian and fascist politics, it was widely discredited for its association with collaboration in German-occupied Belgium during World War II. However, it re-emerged in the post-war period under the auspices of the Volksunie (1954–2002) and increasingly permeated into other parties in Flanders. It played an important role in Belgium's transformation into a federal state through the 1970s and 1980s.
