Second Balkan War

Background and Causes

The Second Balkan War was a conflict that took place in 1913, following the conclusion of the First Balkan War. The primary belligerents were Bulgaria on one side and a coalition of Serbia, Greece, Romania, and the Ottoman Empire on the other. The war was primarily driven by territorial disputes and the dissatisfaction of Bulgaria with the territorial gains it had achieved in the First Balkan War.

The First Balkan War had ended with the signing of the Treaty of London in May 1913, which saw the Ottoman Empire cede almost all of its European territories to the Balkan League, comprising Bulgaria, Serbia, Greece, and Montenegro. However, the division of these territories led to significant disagreements among the allies, particularly between Bulgaria and Serbia over the control of Macedonia.

Prelude to War

The tensions between the former allies escalated rapidly in the months following the Treaty of London. Bulgaria, feeling shortchanged by the territorial allocations, particularly in Macedonia, sought to revise the borders. Serbia, on the other hand, was unwilling to cede any of the territories it had gained. Greece also had territorial ambitions in the region, further complicating the situation.

In an effort to resolve the disputes, a conference was held in Bucharest in June 1913. However, the negotiations failed to produce a satisfactory resolution, and Bulgaria decided to take military action to assert its claims.

Outbreak of Hostilities

The Second Balkan War began on June 29, 1913, when Bulgaria launched a surprise attack on its former allies, Serbia and Greece. The Bulgarian army initially achieved some success, but the tide quickly turned as Serbia and Greece mobilized their forces and launched counterattacks. Romania and the Ottoman Empire also entered the war against Bulgaria, further tipping the balance of power.

Major Battles and Campaigns

Battle of Bregalnica

One of the key battles of the Second Balkan War was the Battle of Bregalnica, which took place from July 30 to August 9, 1913. The battle was fought between Bulgarian and Serbian forces in the region of Bregalnica in present-day North Macedonia. Despite initial Bulgarian advances, the Serbian army, reinforced by Greek troops, managed to repel the Bulgarian forces and secure a decisive victory.

Battle of Kilkis-Lahanas

Another significant engagement was the Battle of Kilkis-Lahanas, fought between Bulgarian and Greek forces from July 19 to July 21, 1913. The battle took place in the region of Kilkis in northern Greece. The Greek army, under the command of King Constantine I, launched a successful offensive against the Bulgarian positions, forcing them to retreat and securing a strategic victory for Greece.

Romanian and Ottoman Campaigns

Romania's entry into the war on July 10, 1913, further complicated Bulgaria's position. The Romanian army advanced into southern Dobruja, facing little resistance from the Bulgarian forces. Meanwhile, the Ottoman Empire took advantage of Bulgaria's weakened state to reclaim some of its lost territories in Thrace, including the city of Adrianople (modern-day Edirne).

Conclusion and Aftermath

The Second Balkan War came to an end with the signing of the Treaty of Bucharest on August 10, 1913. The treaty significantly altered the territorial landscape of the Balkans. Bulgaria was forced to cede significant territories to Serbia, Greece, and Romania, while the Ottoman Empire regained control of parts of Thrace.

The war had far-reaching consequences for the region. The territorial adjustments created new tensions and rivalries, setting the stage for future conflicts. The Second Balkan War also exposed the weaknesses of the Balkan states and their inability to form a lasting alliance, which would have significant implications in the lead-up to World War I.
