Question: Which son of Constantine II was crowned Prince AFTER the Greek monarchy was abolished in 1973?
Context: Princess Tatiana of Greece and Denmark (born Tatiana Ellinka Blatnik, 28 August 1980) is the wife of Prince Nikolaos, son of Constantine II, who reigned as King of Greece until the monarchy was abolished in 1973. Constantine II (Georgian: კონსტანტინე II ) (c. 1447 – 1505), of the Bagrationi dynasty, was a king of Georgia since 1478.  Early in the 1490s, he had to recognise the independence of his rival rulers of Imereti and Kakheti, and to confine his power to Kartli.  In 1505, Constantine II died, and was succeeded by his son David X. 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. 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, 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. The Greek royal family (Greek: Ελληνική Βασιλική Οικογένεια) is a branch of the House of Glücksburg that reigned in Greece from 1863 to 1924 and again from 1935 to 1973.  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".  Most members of the dynasty (aside from the last king to reign, Constantine II and his queen consort, Anne-Marie of Denmark) hold the title "Prince or Princess of Greece and Denmark" with the style "Royal Highness", except Marina, Consort of Prince Michael, and their daughters Princess Alexandra and Princess Olga. The Greek monarchy was abolished by the then-ruling military regime on 1 June 1973, an act that was confirmed by plebiscite on 8 December 1974 after the regime's fall.  The title of king is used by the last reigning monarch, Constantine II (r. 1964–1973).  His son, the Crown Prince Pavlos, who was born in 1967, is the heir apparent to the pretended title. Constantine II (Bulgarian: Константин II Асен , "Konstantin II Asen"), ruled as emperor (tsar) of Bulgaria in Vidin from 1397 to 1422.  He was born in the early 1370s, and died in exile at the Serbian court on 17 September 1422.  Constantine II claimed the title Emperor of Bulgaria and was accepted as such by foreign governments, but he is often omitted from listings of rulers of Bulgaria. Constantine II (Greek: Κωνσταντῖνος Β΄ , "Konstantínos II", ] ; born 2 June 1940) is a former monarch who was the last King of Greece, reigning from 1964 until the abolition of the Greek monarchy in 1973. Pavlos, Crown Prince of Greece, {'1': ", '2': ", '3': 'RE', '4': "} (Greek: Παύλος ; born 20 May 1967) is the eldest son and second child of Constantine II, the last King of Greece from 1964 to 1973 and his wife, Anne-Marie of Denmark.  Pavlos was heir apparent to the throne of Greece and was its crown prince from birth, remaining so during his father's reign until the monarchy's abolition.
Answer: Pavlos, Crown Prince of Greece
