Greek republic referendum, 1973

A constitutional referendum was held in Greece on 29 July 1973. The amendments would abolish the monarchy and establish a republic. The proposal was approved by 78.6% of voters with a turnout of 75.0%. This initiated the first period of the Metapolitefsi.

The military junta had ruled Greece since a group of middle-ranking officers, under the leadership of Colonel Georgios Papadopoulos, staged a coup on 21 April 1967. King Constantine II reluctantly endorsed the coup, but started preparing for a counter-coup by elements of the armed forces loyal to him. This counter-coup was launched on 13 December 1967 and failed, forcing the King and the royal family to flee to Italy. Greece remained a Kingdom, and the King's functions were exercised by a Regent, a post held until 1972 by General Georgios Zoitakis, and then assumed by an increasingly dominant Papadopoulos, who also held the position of Prime Minister and several ministerial posts.

In May 1973, however, a wide-ranging anti-junta movement was discovered and suppressed, just before its outbreak, among the ranks of the mostly royalist Navy. One ship, however, the destroyer Velos did actually mutiny, and upon reaching Italy, the captain Nikolaos Pappas and 31 officers and crew disembarked and asked for political asylum, creating worldwide interest. The failed Navy revolt demonstrated that even after six years of junta "normality", the opposition had not died off, and that it existed even amongst large parts of the armed forces, which were the regime's main internal supporter. This revelation created a major crisis for the junta leadership.

Papadopoulos was thus forced to act, in a move which would bolster his own authority, get rid of the King, and appear as moving into the direction of genuine reforms. On 1 June, a Constituent Act was proclaimed, which declared Greece a presidential republic, with Papadopoulos as President. The Act was to be confirmed by a plebiscite, which was held on 29 July 1973. The defunct political parties and their leaders urged for a "No" as a sign of opposition to the regime, but the vote was tightly controlled by the junta, and the results were predictably favourable to the regime.
