 In July 1831, the Great Powers relented, and the Conference instead decreed that the status of Luxembourg would be decided later; the Netherlands, which had assented to the Conference's decision, invaded Belgium to force the Belgians to accept limitation of its territory.After the withdrawal of this force, the London Conference made its third suggestion, that Luxembourg be divided between the two, with most of the land going to Belgium, but with Luxembourg City remaining under Dutch control.Leopold agreed, and the treaty was signed on the 15 November 1831.
