History of Constantine I of Greece

Constantine I of Greece, a monarch entwined with the turbulent political landscape of early 20th-century Greece, played a pivotal role that shaped the destiny of the nation. His reign (1913-1917, 1920-1922) was marked by political upheaval, national rivalry, and military conflict, reflecting the broader struggles in Europe during and after World War I.

Born on August 2, 1868, as the eldest son of King George I of Greece and Queen Olga, Constantine was destined for a life of leadership. Educated in military academies in Germany and later in Greece, Constantine imbibed the Prussian model of military organization, which influenced his leadership style in the Greek military. His marriage in 1889 to Sophia of Prussia, sister of Emperor Wilhelm II of Germany, further tightened his affiliations with Germanic spheres of influence.

Constantine's early military career was shaped by involvement in the 1897 Greco-Turkish War, where Greece suffered a swift and humiliating defeat against the Ottoman Empire. This experience burned into him the importance of military preparedness and efficiency. Later, as Crown Prince, he played a crucial role in the Balkan Wars (1912-1913), leading Greek forces to impressive victories, including the capture of Thessaloniki. These victories enhanced his popularity and established Greece as a rising power in the Balkans.

In 1913, after the assassination of his father, Constantine ascended to the throne, bearing the weight of a newly expanded Greece. However, his reign was immediately beset by the geopolitical cleavages of World War I. Constantine's pro-German sympathies, largely influenced by his education and family ties, clashed with the prevailing Entente-friendly sentiment of the Greek populace and politicians, including Prime Minister Eleftherios Venizelos.

This friction manifested in the "National Schism" (Ethnikos Dikhasmos), a split between the royalist and Venizelist factions, which embodied the larger entanglement of international alliances. Constantine favored neutrality, arguing Greece's unpreparedness for war, while Venizelos supported alignment with the Entente, believing it would secure Greece's territorial ambitions in Asia Minor.

The schism reached a crescendo in 1916 when Venizelos established a rival provisional government in Thessaloniki with Entente support. This effectively divided Greece into two separate administrations. Under immense pressure and following Entente military interventions, Constantine abdicated in 1917, leaving the throne to his second son, Alexander.

Constantine's first abdication, however, did not mark the end of his influence. After World War I, Greece achieved notable territorial gains at the 1920 Treaty of Sèvres, which delineated a vast increase in Greek lands, particularly in Asia Minor. However, the sudden death of King Alexander and a shifting political landscape prompted Constantine's return to the throne in December 1920 after a controversial plebiscite, despite the continued opposition from the victorious Allied powers.

Upon his return, Constantine faced the daunting task of leading a nation again embroiled in conflict – this time in the Greco-Turkish War (1919-1922). Greek forces, initially successful in their campaigns, aimed to establish Hellenic dominance in Asia Minor by capturing Smyrna, a city with a significant Greek population. However, logistical shortcomings, overextended supply lines, and over-ambitious strategies led to catastrophic failures.

The decisive moment came with the Turkish counteroffensive led by Mustafa Kemal Atatürk, culminating in the 1922 burning of Smyrna and the subsequent rout of Greek forces. This calamity, known as the Asia Minor Catastrophe, prompted a massive population exchange between Greece and Turkey under the Treaty of Lausanne (1923), profoundly altering both regions' demographics.

This defeat eradicated remaining support for Constantine, whose leadership was now synonymous with military disaster and national humiliation. In September 1922, following a revolt by the Greek army, Constantine abdicated for a second time, this time in favor of his eldest son, George II.

Constantine's political legacy remains contentious. For his supporters, he was a champion of Greek nationalism and territorial expansion who fell victim to unfavorable international conditions and internal treachery. Critics point to his autocratic tendencies, pro-German leanings, and failure to unify his country during a critical era of national consolidation.

Constantine spent his final years in exile, primarily in Italy. He died on January 11, 1923, in Palermo, passing away as a symbol of lost opportunity and royal ambition unfulfilled.

In retrospect, Constantine I's political journey mirrors the volatile currents of early 20th-century European geopolitics. His reign encapsulated the dilemmas faced by small nations caught between great powers and internal divisions. Despite his military prowess and initial successes, Constantine's inability to balance domestic and international exigencies ultimately led to his downfall. His life and reign continue to evoke discussions about leadership, loyalty, and the inexorable intersection of politics and war.
