President Makarios took refuge in the British base (Agratur) on the island. The constitution was virtually eliminated. Turkey in order to ensure the safety of Turks on the island by using the guarantor of rights arising from the London and Zurich agreements sent troops to the island. It took the northernmost of island (36.5% - 3355 square kilometers). The Greeks in the north took refuge in the south and the Turks in the south took refuge in the north.
