15. The Second Balkan War (1913)
The Second Balkan War, fought from June 29 to August 10, 1913, was a brief yet pivotal conflict among former allies over the division of territories gained in the First Balkan War. Bulgaria, dissatisfied with its share, launched attacks on Serbia and Greece, leading to a rapid escalation as Romania and the Ottoman Empire intervened. The war concluded with the Treaty of Bucharest, which redistributed territories and set the stage for future regional tensions, influencing the political landscape of the Balkans.
