The abdication of King Constantine I of Greece marked a significant turning point in Greek history. It occurred in a climate of crisis following the disastrous Greco-Turkish War (1919-1922), where Greece faced significant military losses against Turkey, leading to a humanitarian disaster for Greek populations in Asia Minor. Following the military defeats and subsequent political chaos, Greek leaders pressured Constantine to step down, especially as his pro-German stance during World War I had made him unpopular among the Allies. Faced with increasing public dissent and coup threats from within the military, he relinquished the throne in September 1922 in favor of his eldest son, George II.George II was proclaimed king shortly after his father's departure, taking over a nation struggling with social, political, and economic turmoil. Constantine's abdication precipitated a period of political instability in Greece that saw the abolition and reinstatement of monarchy over the following decades. The ascension of George II was seen as a potential means to unite a divided nation and address the aftermath of the war. However, the challenges that Greece faced—ranging from managing refugee crises to addressing social unrest—made the transition formidable. Ultimately, the monarchy would undergo further upheavals, including a shift to a republic and back to monarchy in the years that followed. This event highlighted the shifting tensions within Greek society and the broader geopolitical struggles in the Balkans during the early 20th century.
