The following is a family tree for the Kings of the Hellenes of the House of Schleswig-Holstein-Sonderburg-Glücksburg, which ruled Greece between the election of Prince Wilhelm of Denmark (George I) to replace Otto of Greece in 1863, who was born Prince William of Schleswig-Holstein-Sonderburg-Glücksburg, on 24 December 1845, and was King of Greece from 1863 until his assassination in 1913?
George I of Greece George I (Greek: Γεώργιος Α΄ , "Geórgios I"; born Prince William of Schleswig-Holstein-Sonderburg-Glücksburg; 24 December 1845 – 18 March 1913) was King of Greece from 1863 until his assassination in 1913.
Nikolaos Plastiras Nikolaos Plastiras (Greek: Νικόλαος Πλαστήρας ; 4 November 1883  – 26 July 1953) was a Greek general and politician, who served thrice as Prime Minister of Greece. A distinguished soldier and known for his personal bravery, he was known as "The Black Rider" during the Greco-Turkish War of 1919-1922. After the Greek defeat in the war, along with other Venizelist officers he staged a coup against King Constantine I of Greece and his government. The military-led government ruled until January 1924, when power was handed over to an elected National Assembly, which later declared the Second Hellenic Republic. In the interwar period, Plastiras remained a devoted Venizelist and republican. Trying to avert the rise of the royalist People's Party and the restoration of the monarchy, he led two coup attempts in 1933 and 1935, both of which failed, forcing him to exile in France.
