The Treaty of London (1913) was signed on 30 May following the London Conference of 1912–1913. It dealt with the territorial adjustments arising out of the conclusion of the First Balkan War. The London Conference had ended on 23 January 1913, when the 1913 Ottoman coup d'état took place and Ottoman Grand Vizier Kâmil Pasha was forced to resign. Coup leader Enver Pasha withdrew the Ottoman Empire from the Conference, and the Treaty of London was signed without the presence of the Ottoman delegation.

The London Conference of 1912–1913, also known as the London Peace Conference or the Conference of the Ambassadors, was an international summit of the six Great Powers of that time convened in December 1912 due to the successes of the Balkan League armies against the Ottoman Empire in the First Balkan War. In particular, the conference intended to arbitrate between the warring powers as to territorial acquisitions, and also to determine the future of Albania, whose independence was proclaimed during the conflict.
