The revolt in 1830 that led to the independence of Belgium from the Netherlands is known as the Belgian Revolution. Triggered by rising discontent over religious, linguistic, and economic differences, the revolution began on August 25, 1830, following a performance of an Italian opera that incited French-speaking citizens against the Dutch-speaking regime. The revolutionaries quickly gained ground, declaring independence on October 4, 1830. The success of the rebellion was recognized at the London Conference of 1830, ultimately leading to official independence for Belgium and the establishment of a constitutional monarchy.
