Constantine II (Greek: Κωνσταντίνος Βʹ, Konstantínos II, pronounced [ˌkonstanˈdinos]; born 2 June 1940) is the former King of the Hellenes who reigned from 6 March 1964 until the abolition of the monarchy on 1 June 1973.
He acceded as king following the death of his father King Paul in March 1964. Later that year he married Princess Anne-Marie of Denmark with whom he eventually had five children. Although the accession of the young monarch was initially regarded auspiciously, his reign saw political instability that culminated in the Colonels' Coup of 21 April 1967. The coup left Constantine, as the head of state, little room to manoeuvre since he had no loyal military forces on which to rely. As a result, he reluctantly agreed to inaugurate the junta on the condition that it be made up largely of civilian ministers. On 13 December 1967, Constantine was forced to flee the country, following an unsuccessful countercoup against the junta. He remained (formally) the head of state in exile until the junta abolished the monarchy on 1 June 1973. The 1973 Greek republic referendum on 29 July, ratified the abolition. There were questions concerning the validity of this referendum and whether people were pressured to vote for a republic. Therefore a fresh referendum was held after the restoration of democracy in 1974. This second referendum was held after the fall of the junta as the 1974 Greek republic referendum on 8 December 1974 and confirmed the abolition of the monarchy and the establishment of the Third Hellenic Republic. Constantine, who was not allowed to return to Greece to campaign,[1] accepted the results of the plebiscite.[2]
