On August 4, 2025, the historical community marks the 131st anniversary of one of the most significant diplomatic documents in modern Balkan history – the Berlin Treaty, which fundamentally changed the geopolitical landscape of the peninsula.
The agreement, signed immediately after the Russo-Turkish War (1877-1878), represents a fundamental international act of exceptional importance for the formation of state borders and national identity of the Balkan peoples.
The document officially regulates the status of the newly created Principality of Bulgaria, redraws the territorial outlines of the Ottoman Empire, and lays the foundations for the future development of states in the region.
Historical analysts define the Berlin Treaty as a turning point that exerts long-term influence on geopolitical processes in Southeast Europe in the following decades.
Its significance continues to be the subject of in-depth studies, considered a key moment in the evolution of national statehood and international relations in the Balkans.
