1913 - Constantine I, King of Greece
King of Greece after 1913, he served in the Prussian Imperial Guard in his youth. His military career included some turbulent moments; however, after some initial setbacks he was able to prove his military worth in the First Balkan War, which gained him public favour. During the First World War Constantine showed pro-German sympathies, in contrast to Prime Minister Venizelos, who supported the entente powers. Conflict between the monarchy and its followers, and the government, is recognized today as having been a national schism in Greece. In the end, it led to Constantine’removal from the throne in 1917, although he returned in 1920. He was a guest in Książ Castle in the same year that his coronation took place.
