Answer:
constantine ii -lrb- , '' konstantinos ii '' ; ; born 2 june 1940 -rrb- was the king of greece from 1964 until the abolition of the monarchy in 1973 .he is also by birth a prince of denmark .he succeeded his father paul in march 1964 , being styled '' his majesty '' '' constantine ii , king of the hellenes '' -lrb- -rrb- .although the accession of the young monarch was initially regarded auspiciously , his reign soon became controversial : constantine 's involvement in the '' apostasia '' of july 1965 created unrest among sections of the population and aggravated the ongoing political instability that culminated in the colonels ' coup of 21 april 1967 .the coup was successful , leaving constantine , as head of state , little room to manoeuvre as he had no loyal military forces to rely on .as a result , he reluctantly agreed to inaugurate the putschist government on the condition that it be made up largely of civilian ministers .on 13 december 1967 , he was forced to flee the country , following an abortive counter-coup against the junta .he remained the head of state in exile until 1 june 1973 , when the junta abolished the monarchy .this abolition was confirmed after the fall of the junta by a plebiscite on 8 december 1974 , which established the third hellenic republic .constantine , who was not allowed to return to greece to campaign , accepted the results of the plebiscite .
