What was the significance of the Treaty of Istanbul?

The Treaty of Istanbul, also known as the Treaty of Constantinople, was signed on August 10, 1913, between the Ottoman Empire and the Balkan League (Bulgaria, Serbia, Greece, and Montenegro) after the conclusion of the First Balkan War. The significance of this treaty was that it marked the end of the Ottoman Empire's control over most of its European territories. The Ottoman Empire lost significant territories in the Balkans, including Macedonia, Albania, and parts of Thrace. This treaty weakened the Ottoman Empire's position in Europe and set the stage for further territorial losses in the following years.
