The Ecclesiastical coup is the name given to the events staged by three bishops of the Orthodox Church of Cyprus against the President of the Republic of Cyprus, Archbishop Makarios III, in the period from March 1972 to July 1973.
At the session of the Holy Synod of the Orthodox Church of Cyprus held on 2 March 1972, Metropolitan Gennadios (Machairiotis) of Paphos, Metropolitan Anthemos (Machairiotis) of Kition and Metropolitan Kyprianos (Kyriakides) of Kyrenia tabled a motion proposing that Archbishop Makarios III resign the Presidency of the Republic of Cyprus. They held that the holding of secular office by a cleric was against the canons of the Church. The Synod released an announcement reporting the position of the bishops, and stating that the Archbishop would announce his response at a later time.
Makarios issued his response on 19 March. In it he accused the three bishops of having conspired among themselves and with other people outside the church, hinting at the Junta of the Colonels ruling Greece at the time, and at George Grivas, leader of the EOKA guerrilla organization, who had secretly returned to Cyprus. Makarios argued that the office of President of the Republic of Cyprus could not be called secular at a time when the Orthodox Greeks of Cyprus were struggling for their national survival, and that in the circumstances the holding of secular office did not confer on the Archbishop any personal reward, but was an onerous and bitter duty which he could not shirk.
