Constantine II of Georgia: Constantine II (Georgian: კონსტანტინე II ) (c. 1447 – 1505), of the Bagrationi dynasty, was a king of Georgia since 1478.

Greek Constitution of 1973: The Greek Constitution of 1973 (Greek: Σύνταγμα του 1973 ) was an amended version of the Greek Constitution of 1968 (which was never fully enacted) by Greek dictator Georgios Papadopoulos, with the aim of abolishing the Greek monarchy.  Papadopoulos's rewrite of the 1968 constitution replaced the terms "parliamentary monarchy" and "king" with "republican democracy" and "president of Greece".  The constitution was never enacted due to Papadopoulos's failed attempt at liberalisation of his regime.

11 September 1922 Revolution: The 11 September 1922 Revolution (Greek: Επανάσταση της 11ης Σεπτεμβρίου 1922 ) was an uprising by the Greek army and navy against the government in Athens.  The Greek Army had just been defeated in the Asia Minor Campaign in mainland Turkey and had been evacuated from Anatolia to the Greek islands in the eastern Aegean.  Discontent among the middle-ranking officers and men for the campaign's conduct by the royal government boiled over into armed revolt led by pro-Venizelist and anti-royalist officers.  The mutiny spread quickly and seized power in Athens, forcing King Constantine I to abdicate and leave the country, with a military government ruling the country until early 1924, shortly before the Greek monarchy was abolished and the Second Hellenic Republic established.

Constantine II of Scotland: Constantine, son of Áed (Medieval Gaelic: "Constantín mac Áeda"; Modern Gaelic: "Còiseam mac Aoidh", known in most modern regnal lists as Constantine II; died 952) was an early King of Scotland, known then by the Gaelic name "Alba".  The Kingdom of Alba, a name which first appears in Constantine's lifetime, was in northern Great Britain.  The core of the kingdom was formed by the lands around the River Tay.  Its southern limit was the River Forth, northwards it extended towards the Moray Firth and perhaps to Caithness, while its western limits are uncertain.  Constantine's grandfather Kenneth I of Scotland (Cináed mac Ailpín, died 858) was the first of the family recorded as a king, but as king of the Picts.  This change of title, from king of the Picts to king of Alba, is part of a broader transformation of Pictland and the origins of the Kingdom of Alba are traced to Constantine's lifetime.

Its first monarch was George I, the second son of King Christian IX of Denmark.  He and his successors styled themselves "Kings of the Hellenes".
