Constantinople Treaty

The Constantinople Treaty of 1913 was an agreement between Bulgaria and the Ottoman Empire, confirming the transfer of territories in the Western Thrace region from Bulgaria to the Ottomans. This treaty established Bulgaria's southeastern border, giving the Ottomans control over areas like Edirne (Adrianople). It helped define territorial boundaries following the Balkan Wars, stabilizing relations between the two countries in that region. The treaty was significant in shaping the geopolitical landscape of the Balkans during that period.
