Tension began in 1963 when Makarios proposed thirteen amendments to the constitution of the Republic of Cyprus. Turkish Cypriots were opposed to the proposal since it removed some of the rights they received as part of the 1960 settlement. On 21 December 1963, clashes between Greek Cypriots and Turkish Cypriots erupted, with Greek Cypriot paramilitaries and Turkish Cypriots slaughtering each other.[citation needed]
Between 1963 and 1974 sporadic violence erupted with both Greek and Turkish Cypriots accusing the other of committing atrocities. By 1974 thousands of Turkish Cypriots were living in enclaves, enduring poor living conditions in exchange for security from violent attacks, while Greek Cypriots took over the properties that Turkish Cyrpiots had to leave behind.[citation needed]
By 1974, dissatisfaction among Greek nationalist right-wing elements in favour of the long-term goal of Enosis precipitated a coup d'etat against President Makarios which was sponsored by the military government of Greece and led by the Cypriot National Guard. The new regime replaced Makarios with Nikos Giorgiades Sampson as president, and Bishop Gennadios as head of the Cypriot Orthodox Church. Seven days after these events, and after the coup d'etat had already failed, Turkey intervened militarilly in Cyprus by sea and air on 20 July 1974. At the time Turkey claimed it was invading to uphold its obligation under the 1960 Treaty of Guarantee. Talks in Geneva involving Greece, Turkey, the United Kingdom and the two Cypriot factions failed in mid-August, and Turkish forces subsequently moved from the previous cease-fire lines to gain control of 37% of the island's territory. During the invasion, over 160,000 Greek Cypriots [3] were displaced from their home land, while Turkish forces killed several thousand Greek Cypriots captured in the occupied areas. While this was happening, several hundred Turkish Cypriots in the south were killed at the hands of Greek Cypriot paramilitaries.[citation needed] As of today, there are still thousands of Greek Cypriots and Turkish Cypriots unaccounted for. The events of the summer of 1974 have dominated Cypriot politics ever since and have been a major point of contention between Greece and Turkey.
Since 1974, there have been continual efforts to negotiate a settlement, which met with varying levels of hostility from either side. Since 18% of the population was left in control of 37% of the territory, including some of the most fertile and productive land, the Turkish government arranged an influx of settlers from Turkey whose exact numbers are disputed, but believed to be in the range of over 100,000. Turkey counters that the Turkish Cypriots - before 1963 - owned and farmed 33% of Cypriot land before being forced into enclaves, thus the take-over of one-third of Cyprus was seen as compensating the Turkish Cypriots for their lost land. This figures are rejected by the Cyprus Republic Authorities as fictional. According to the records held by the Cyprus Land Registry, only 12,3% of all cypriot land, or 16,7% of privately owned land was owned by Turkish Cypriots. Of the 3.241.930.428 square meters of the occupied area, 60,27% is owned by Greek Cypriots, 16,39% is owned by Turkish Cypriots and 23,09% is state owned land.
Turkish Cypriots proclaimed a separate state, the Turkish Republic of Norther Cyprus (TRNC), under Rauf Denktaş on November 15, 1983. The UN Security Council, in its Resolution 541 of November 18, 1983, declared the action illegal and called for withdrawal. Turkey is the only country to date that recognises the administration on the northern third of Cyprus (known as the Turkish Republic of Northern Cyprus. Turkey does not recognise the Republic of Cyprus's authority over the whole island, and refers to it as the Greek Cypriot administration.
Cyprus joined the European Union as a full member in May 2004. Although it was the island as a whole which joined (theoretically including the northern areas) the Acquis communautaire applies only to those (Greek) areas under the control of the Republic of Cyprus.
Since the invasion, the economy of Cyprus has grown greatly and enjoys a high standard of living. The north maintains a lower standard of living due to heavy dependence on Turkey on all aspects of economic activity, as a result of the embargo placed upon it by every nation other than Turkey.
Despite the fact that the self-proclaimed Turkish Republic of Northern Cyprus is recognised only by Turkey, tourism has grown in the north, giving the economy a much needed boost. Indeed, the administration in the north has allowed the sale of real estate, including property and land still owned by Greek Cypriots since before the 1974 Turkish invasion, to private buyers from overseas. In 2005, the UK's Guardian Newspaper reported that up to 10,000 Europeans had invested in property in the north of Cyprus, a trend that still causes concern in the south. This concern was highlighted by the UK's Telegraph Newspaper in 2006 when the wife of Britain's prime minister, Cherie Blair, touched a diplomatic nerve; Mrs Blair, in her capacity as an advocate at law, represented a UK couple, the Orams, who had been taken to court by Greek Cypriots who claimed ownership of the land on which the Orams had built a house. President Tassos Papadopoulos of Cyprus referred to Blair's decision to represent the Orams as "a provocative action".
