Alexander of Greece
Alexander became king after his father, King Constantine XII, was forced to abdicate. Because Alexander's older brother, Crown Prince George, was not yet ready to rule, Alexander became king. During his reign, the king supported Greek troops during their war against the Ottoman Empire and Bulgaria. Under his reign, the territorial extent of Greece considerably increased, following the victory of the Entente and their Allies in the First World War and the early stages of the Greco-Turkish War of 1919–1922.
