when belgium declared its independence in 1830 it broke away from ___ control
Belgian Revolution Dutch units saw the mass desertion of recruits from the southern provinces and pulled out. The States-General in Brussels voted in favour of secession and declared independence. In the aftermath, a National Congress was assembled. King William refrained from future military action and appealed to the Great Powers. The resulting 1830 London Conference of major European powers recognized Belgian independence. Following the installation of Leopold I as "King of the Belgians" in 1831, King William made a belated military attempt to reconquer Belgium and restore his position through a military campaign. This "Ten Days' Campaign" failed because of French military intervention. Not until 1839 did the Dutch accept the decision of the London conference and Belgian independence by signing the Treaty of London.
