On 21 April 1967, a coup d'état in Greece brought to power a military administration. Just months later, in November 1967, Cyprus witnessed its most severe bout of intercommunal fighting since 1964. Responding to a major attack on Turkish Cypriot villages in the south of the island, which left 27 dead, Turkey bombed Greek Cypriot forces and appeared to be readying itself for an intervention. Greece was forced to capitulate. Following international intervention, Greece agreed to recall General George Grivas, the Commander of the Greek Cypriot National Guard and former EOKA leader, and reduce its forces on the island. Capitalising on the weakness of the Greek Cypriots, the Turkish Cypriots proclaimed their own provisional administration on 28 December 1967. Makarios immediately declared the new administration illegal. Nevertheless, a major change had occurred. The Archbishop, along with most other Greek Cypriots, began to accept that the Turkish Cypriots would have to have some degree of political autonomy. It was also realised that unification of Greece and Cyprus was unachievable under the prevailing circumstances.
