Historical overview

Belgium’s modern political history developed through the changing political arrangements of the Low Countries, European revolutionary movements, industrialisation and the creation of a constitutional monarchy.

Following the defeat of Napoleon, the Congress of Vienna in 1815 united the northern and southern Netherlands under King William I. Religious, political, economic and linguistic disagreements contributed to growing opposition in the southern provinces.

The Belgian Revolution began in Brussels in August 1830. On 4 October 1830, the Provisional Government declared Belgian independence. The National Congress subsequently adopted the Constitution on 7 February 1831, establishing Belgium as a constitutional parliamentary monarchy. For its time, the Constitution contained significant protections for freedom of religion, the press, association and education. However, electoral participation was initially restricted to a small property-owning male electorate. Belgium.beBelgium industrialised rapidly during the nineteenth century. Its overseas colonial expansion under King Leopold II had devastating consequences in Central Africa. The Congo Free State was recognised internationally in 1885 and was controlled personally by Leopold II. Reports of forced labour, violence, hostage-taking and mass abuses generated international criticism. In 1908, control was transferred to the Belgian state, creating the Belgian Congo.

Belgium experienced German occupation during both World Wars. During the First World War, German forces invaded in August 1914, and the country became a major theatre of occupation and resistance. In the Second World War, Germany invaded again in May 1940. Belgium was liberated by Allied forces in 1944–45.

After the war, Belgium expanded its welfare state and gradually transformed its political structure. Linguistic and regional disputes led to successive constitutional reforms beginning in 1970. The 1993 constitutional reform formally transformed Belgium into a federal state, with regions and language communities exercising constitutionally defined powers. PFWB

Editorial note: Belgian colonial history is especially important for a global democracy and human-rights archive. The Congo Free State period (1885–1908) must be distinguished from Belgian state colonial rule (1908–60). Include Congolese perspectives and the archival voices of people affected by colonial exploitation. The Belgian State Archives itself acknowledges that these records form shared cultural heritage and that their transfer to Belgium has created challenges for African researchers and communities.
