The national flag of Cyprus (Greek: Σημαία της Κύπρου simea tis Kipru, Turkish: Kıbrıs bayrağı) came into use on August 16, 1960, under the Zurich and London Agreements, whereby a constitution was drafted and Cyprus was proclaimed an independent state. The flag was designed by art teacher İsmet Güney. The flag deliberately chose peaceful and neutral symbols in an attempt to indicate harmony between the rival Greek and Turkish communities, an ideal that has not yet been realized. In 1963 Turkish Cypriot and Greek Cypriot communities separated because of Cypriot intercommunal violence. The state flag features a map of the entirety of the island, with two olive branches below (a symbol of peace) on white (another symbol of peace). The olive branches signify peace between the Turks and Greeks. The map on the flag is a copper-orange colour, symbolizing the large deposits of copper ore on the island (chiefly in the form of chalcopyrite, which is yellow in colour), from which it may have received its name.
