Charles I of Greece was born on September 20, 1890, and became King of Greece in 1922. He was a member of the House of Glücksburg and ascended to the throne during a tumultuous period in Greek history, marked by political instability and military challenges. His reign was characterized by efforts to stabilize the country and navigate the aftermath of the Greco-Turkish War. In 1924, Charles I was forced to abdicate following a referendum that established a republic in Greece. He spent the remainder of his life in exile, returning briefly to Greece in 1935 before his death on April 1, 1947. His legacy remains intertwined with the complexities of Greek monarchy and republicanism.
