Constantine I ascended to the Greek throne in 1913 following the assassination of his father, King George I. His two distinct reigns, separated by forced abdication and exile, were defined by internal political fracture and external military instability. As a sovereign, he maintained deep ties to Prussian military tradition while navigating the volatile national identity of a rapidly expanding Greek state.
Military Education and Early Career
Born in Athens in 1868, Constantine received his foundational military instruction at the Hellenic Military Academy before relocating to Germany. During his tenure in Berlin, he served in the German Imperial Guard and attended Heidelberg University to study political science. He eventually attained the rank of general field marshal. His initial command of the Hellenic Army during the 1897 Greco-Turkish War resulted in a significant defeat, which damaged the standing of the monarchy.

Before his accession, Constantine played a visible role in public life. In 1895, he ordered forces to disperse street protests, causing a constitutional rift with Prime Minister Charilaos Trikoupis that led to the minister's resignation. He later served on the Hellenic Olympic Committee and acted as president of the organizing committee for the 1896 Summer Olympics. His influence secured the funding necessary for the restoration of the Panathinaiko Stadium.
The National Schism and World War I
His leadership during the 1912–1913 Balkan Wars initially bolstered his reputation, as Greece expanded its territory. However, his tenure as King of the Hellenes was quickly marred by the National Schism. Disagreeing with Prime Minister Eleftherios Venizelos regarding Greek involvement in World War I, Constantine refused to support the Allies. His pro-German policies, including the surrender of Fort Roupel to Bulgarian forces and the Noemvriana incident, led to an Allied naval blockade. He abdicated for the first time in 1917.
Restoration and Final Exile
Constantine was reinstated in 1920 following the death of his son Alexander and a change in government. His second reign saw the continuation of the Greco-Turkish War, which concluded in 1922 with the destruction of Greek communities in Asia Minor. Following a military revolt led by Venizelist officers, he abdicated again in 1922 in favor of George II. He died in 1923 in Palermo, Italy.
