 The Republic was maintained, but was nothing more than a façade for the military regime until August 1974, when the Turkish invasion of Cyprus led to the collapse of the Junta.After the fall of the regime and the return to civilian rule in August 1974 however, the legal and constitutional acts of the Junta were deemed invalid, and a new referendum was held on 8 December 1974, which finally abolished the monarchy.A new Constitution, promulgated on 11 June 1975, declared Greece a "presidential parliamentary democracy" (or "republic" – the Greek δημοκρατία can be translated both ways).
