The First Balkan War produced a military defeat for the Ottoman Empire, requiring a diplomatic settlement over its European territories. The London Conference of 1912–1913 was convened to negotiate terms, but collapsed on 23 January 1913 when the Ottoman coup d'état removed Grand Vizier Kâmil Pasha and coup leader Enver Pasha withdrew the empire from negotiations.
On 30 May 1913, the Treaty of London was signed without Ottoman participation, formally concluding the First Balkan War. The treaty established territorial adjustments arising from the Ottoman defeat, transferring significant portions of the empire's remaining European possessions to the Balkan League states.
The territorial settlement reshaped the political map of southeastern Europe but left outstanding disputes among the victorious Balkan states. These unresolved tensions led directly to the Second Balkan War, with further border changes ratified under the Treaty of Bucharest in August 1913.
Political Outcome
Formal end of the First Balkan War; Ottoman Empire ceded most remaining European territories without representation at signing.
Ottoman Empire held substantial territories in the Balkan Peninsula
Balkan League states absorbed most Ottoman European territory; Ottoman presence in Europe drastically reduced
