19-APR-1839 :- The Treaty of London Establishes

The Treaty of London of 1839, also called the First Treaty of London, the Convention of 1839, the London Treaty of Separation, the Quintuple Treaty of 1839, or the Treaty of the XXIV articles, was a treaty signed on 19 April 1839 between the Concert of Europe, the United Kingdom of the Netherlands and the Kingdom of Belgium. It was a direct follow-up to the 1831 Treaty of the XVIII Articles which the Netherlands had refused to sign, and the result of negotiations at the London Conference of 1838–1839.

Under the treaty, the European powers recognized and guaranteed the independence and neutrality of Belgium and confirmed the independence of the German-speaking part of Luxembourg. Article VII required Belgium to remain perpetually neutral, and by implication committed the signatory powers to guard that neutrality in the event of invasion.
