World War II: Bulgaria and the Soviet Union successfully complete their defense of the north bank of the Drava River as the Battle of the Transdanubian Hills concludes.

The dawn of the 20th century in Southeastern Europe saw the emergence of a powerful new entity: the Tsardom of Bulgaria. Often referred to as the Third Bulgarian Tsardom, and sometimes translated in English as the Kingdom of Bulgaria, this constitutional monarchy officially came into being on October 5, 1908 (or September 22 by the Old Style calendar). This pivotal moment marked the elevation of the Bulgarian state from a principality to a full-fledged tsardom, a significant declaration of sovereignty on the international stage.

Establishment and Aspirations

At the heart of this transformation was Ferdinand I, the shrewd and ambitious founder of the royal family. His coronation as Tsar coincided with the Declaration of Independence, a move primarily driven by his ambitious military plans and an unwavering desire to unite all lands in the Balkan region with an ethnic Bulgarian majority. These were territories that, following the Congress of Berlin in 1878 and the subsequent Treaty of Berlin, had been regrettably seized from Bulgaria and returned to the Ottoman Empire. Ferdinand envisioned a Greater Bulgaria, restoring what he perceived as historical injustices.

Ferdinand I: A Vision for Greater Bulgaria

Ferdinand’s strategic vision was clear: to consolidate Bulgarian identity and power by reclaiming historically significant territories. The shift from principality to Tsardom of Bulgaria wasn't merely a change in title; it was a bold assertion of national ambition, positioning Bulgaria as a key player in the volatile geopolitical landscape of the Balkans. This period ignited fervent nationalistic sentiments, laying the groundwork for future conflicts as Bulgaria sought to fulfill its irredentist goals.

A Nation Forged in Conflict: The "Balkan Prussia"

Throughout its existence, the Tsardom of Bulgaria found itself almost constantly embroiled in conflict, earning it the stark but fitting nickname, "the Balkan Prussia." This moniker highlighted its militaristic nature and its readiness to employ force to achieve its national objectives. For several years, despite having a population of only about 5 million, Bulgaria impressively mobilized an army exceeding 1 million people, demonstrating a remarkable commitment to its military endeavors.

The Balkan Wars and World War I

The 1910s proved to be a particularly turbulent decade for the Kingdom of Bulgaria. It engaged in three major wars that reshaped the region: the First Balkan War, the Second Balkan War, and the devastating First World War. Each conflict saw Bulgaria battling for territorial gains, often with mixed results. Following its participation in the First World War, Bulgaria, aligned with the Central Powers, found itself on the losing side. As a consequence, its formidable army was disbanded and prohibited from existing by the Allied Powers, and all ambitious plans for the national unification of Bulgarian lands tragically failed, leaving deep scars on the national psyche.

Bulgaria in World War II and the End of the Monarchy

Less than two decades after the Great War, Bulgaria once again felt the pull of national unification, entering the global conflagration of the Second World War. Initially aligning with the Axis powers, it once again found itself on the losing side. However, in a dramatic turn of events in 1944, the Tsardom of Bulgaria strategically switched allegiance to the Allies. This political maneuvering could not, however, save the monarchy. In 1946, the venerable institution was abolished, and its final Tsar was sent into exile. The Kingdom of Bulgaria was subsequently replaced by the People's Republic of Bulgaria, marking the end of an era and the beginning of a new political system.

A Key Defensive Stand: The Battle of the Transdanubian Hills

Amidst the broader canvas of Bulgaria's participation in World War II, a significant engagement known as the Battle of the Transdanubian Hills stands out. Also recognized in Bulgaria as the Drava Operation (Dravska operatsiya), this was a crucial defensive operation carried out by the Bulgarian First Army. From March 6 to March 21, 1945, Bulgarian forces fiercely defended against German Wehrmacht units, who were attempting to capture the strategic north bank of the Drava river as part of their larger offensive, Operation Spring Awakening. Despite intense combat, the German attacks failed to achieve their objectives. Their efforts were ultimately eclipsed by the massive, large-scale Soviet offensive sweeping from the area of Lake Balaton towards Vienna, further solidifying the eventual Allied victory in the region.
