A neutral explainer on the division of Cyprus: how it happened, how the Turkish Republic of Northern Cyprus came about, where international law stands, and what travellers need to know.
Last reviewed on 27 September 2026.
The island of Cyprus has been divided since 1974. The south is governed by the Republic of Cyprus, an internationally recognised state and a member of the European Union. The north is administered by the Turkish Republic of Northern Cyprus (TRNC; in Turkish, Kuzey Kıbrıs Türk Cumhuriyeti, KKTC), which declared independence in 1983 and is recognised as a state only by Türkiye. Between them runs a United Nations buffer zone. This page sets out the main facts, the international legal position and the principal perspectives as neutrally as possible, followed by practical notes for travellers.
Cyprus was part of the Ottoman Empire from 1571 until 1878, when administration passed to Britain; it became a British Crown colony in 1925. Under Ottoman rule a Turkish-speaking Muslim community settled alongside the Greek-speaking Orthodox majority. From the 1950s a Greek Cypriot armed campaign against British rule sought enosis, union with Greece, while many Turkish Cypriots came to favour taksim, partition.
Cyprus became independent on 16 August 1960 under the Zurich and London agreements. The constitution created a bicommunal state with a Greek Cypriot president (Archbishop Makarios III) and a Turkish Cypriot vice-president, fixed shares of posts for each community, and separate communal institutions. A Treaty of Guarantee made Britain, Greece and Türkiye guarantors of the settlement, with a right to take action to restore it, and Britain retained two Sovereign Base Areas on the island, which it still holds today.
The arrangement proved fragile. In late 1963 President Makarios proposed constitutional amendments that Greek Cypriots saw as necessary to make the state workable and Turkish Cypriots saw as an attempt to remove their guaranteed rights. Violence broke out in December 1963 and continued into 1964, with casualties on both sides and many Turkish Cypriots moving into defended enclaves. Turkish Cypriot officials withdrew from, or were excluded from, the institutions of government — the two sides describe this differently — and from then on the Republic's institutions were run by Greek Cypriots. In Nicosia a ceasefire line was drawn on a map in green ink, the origin of the name "Green Line". In March 1964 the UN Security Council established a peacekeeping force, UNFICYP, which remains on the island.
On 15 July 1974 the Cyprus National Guard, backed by the military government then ruling Greece, overthrew President Makarios in a coup aimed at union with Greece. On 20 July Türkiye launched a military intervention, citing its rights as a guarantor power under the Treaty of Guarantee and the need to protect Turkish Cypriots. The coup government and the military government in Athens both collapsed within days. Negotiations in Geneva broke down, and in a second offensive in August 1974 Turkish forces extended their control to roughly a third of the island, along a line running from the north-west coast through Nicosia to Famagusta (Ammochostos/Gazimağusa).
The human cost was severe. Large numbers of Greek Cypriots fled or were expelled from the north, and many Turkish Cypriots moved from the south to the north, in the years immediately following; together these movements displaced a substantial part of the island's population. Thousands of people were killed, and hundreds from both communities remained missing for decades. A bicommunal Committee on Missing Persons, working under UN auspices, has since recovered and identified the remains of many of them.
How these events are described remains deeply contested. The Republic of Cyprus, Greece and most of the international community regard the Turkish military presence in the north since 1974 as an occupation. Türkiye and the Turkish Cypriot leadership regard the intervention as a lawful action under the Treaty of Guarantee that protected Turkish Cypriots, and describe the Turkish troops in the north as a guarantee of their security. The European Court of Human Rights has held Türkiye responsible under the European Convention for human-rights matters in the north, notably in cases concerning displaced Greek Cypriots' property.
Since 1974 the ceasefire lines have been separated by a UN-controlled buffer zone that runs across the island for around 180 kilometres. It is only metres wide in the divided old centre of Nicosia (Lefkosia/Lefkoşa) and several kilometres wide elsewhere. The name "Green Line" is now used loosely for the whole dividing line. The former resort district of Varosha (Maraş) in Famagusta was fenced off and left empty after 1974; parts of it have been opened to visitors since 2020, a step criticised by the Republic of Cyprus and the UN Security Council as contrary to earlier resolutions.
In 1975 the Turkish Cypriot leadership proclaimed a Turkish Federated State of Cyprus, presenting it as the basis of a future federation. On 15 November 1983, under its leader Rauf Denktaş, the Turkish Cypriot assembly declared the independent Turkish Republic of Northern Cyprus. Türkiye recognised it immediately.
Three days later the UN Security Council adopted Resolution 541 (1983), which deplored the declaration, considered it legally invalid, called for its withdrawal, and called on all states not to recognise any Cypriot state other than the Republic of Cyprus. A further resolution in 1984, Resolution 550, condemned the exchange of ambassadors between Türkiye and the TRNC. No state other than Türkiye has recognised the TRNC. In international law, therefore, the Republic of Cyprus is regarded as the sovereign state for the whole island, though its government has no effective control over the north.
The TRNC nevertheless functions as a self-governing polity, with its own elected president and parliament, courts, police and civil service, and it holds regular, competitive elections. It relies heavily on Türkiye for economic support and defence. In 2022 it was admitted as an observer to the Organisation of Turkic States, which is not the same as recognition as a state.
UN-facilitated negotiations have continued, on and off, since the 1970s. The long-standing framework agreed by the two leaders in 1977 and 1979 was a bicommunal, bizonal federation with political equality for both communities. The closest the island has come to a settlement was the Annan Plan, a comprehensive UN proposal put to separate, simultaneous referendums on 24 April 2004. Around 65 per cent of Turkish Cypriot voters accepted it; around 76 per cent of Greek Cypriot voters rejected it. Because it required approval by both communities, the plan fell.
Supporters of the "no" vote in the south argued that the plan did not adequately address the presence of Turkish troops, the return of property and the position of settlers from Türkiye, and that it gave too little security for a reunited state. Turkish Cypriot supporters of the plan hoped it would end their international isolation. Later rounds of talks, most recently at Crans-Montana in 2017, also ended without agreement. Since then the Turkish Cypriot and Turkish governments have at times advocated a "two-state" solution based on sovereign equality, while the Republic of Cyprus and the UN framework continue to refer to a federation; positions in the north have varied with changes of leadership, and informal UN-hosted contacts have continued.
The Republic of Cyprus joined the European Union on 1 May 2004, a week after the referendums. Legally the whole island is EU territory, but the application of EU law — the acquis communautaire — is suspended in the areas where the government of the Republic does not exercise effective control, under a protocol to the accession treaty. Turkish Cypriots who hold, or are entitled to, Republic of Cyprus citizenship are EU citizens, and many have obtained Republic of Cyprus passports. The EU also provides aid to the Turkish Cypriot community.
For almost thirty years it was very difficult to cross between north and south. In April 2003 the Turkish Cypriot authorities eased restrictions and the first crossing points opened, and within days large numbers of people from both communities crossed to see homes they had left in 1974. More crossing points have opened since, including a pedestrian crossing on Ledra Street in the centre of Nicosia in 2008. Crossings are now routine, though they were closed for a time during the COVID-19 pandemic.
Cyprus is a single, recognised state, and a third of it has been under Turkish military occupation since 1974. Priorities include the withdrawal of Turkish troops, the end of the guarantee system, the rights of displaced people to their property, the missing, and reunification as a federation within the EU.
Turkish Cypriots were pushed out of the shared state in 1963 and suffered intercommunal violence before 1974; Türkiye's intervention ended that danger. Priorities include political equality, security guarantees, and an end to the international isolation that has persisted despite their vote for the Annan Plan.
Because the TRNC is not recognised, international aviation rules mean that flights to its main airport, Ercan (ECN), near Nicosia, generally route through Türkiye; there are frequent services from Istanbul, Ankara, Antalya and other Turkish cities. Ferries run from Mersin and Taşucu on Türkiye's Mediterranean coast to Kyrenia (Keryneia/Girne) and Famagusta. Many visitors instead fly to Larnaca or Paphos in the Republic of Cyprus and cross by land.
The crossing points are staffed on both sides, and you must show a passport or, for EU citizens, a national identity card. The Republic of Cyprus regards Ercan and the northern seaports as illegal points of entry, so arriving in the north and then crossing south can be treated differently from arriving in the south, especially for non-EU nationals. Rules on what goods you can carry across are strict, and hire cars from one side may need separate insurance on the other.
The currency in the north is the Turkish lira; euros and pounds sterling are widely accepted in tourist areas. The south uses the euro. Both sides drive on the left. See money and costs for more on the lira.
Only Türkiye. UN Security Council Resolution 541 of 1983 considered the declaration of the TRNC legally invalid and called on states not to recognise it. Internationally, the Republic of Cyprus is regarded as the sovereign state for the whole island.
After independence in 1960, the bicommunal state broke down amid intercommunal violence in 1963–64. In July 1974 a coup backed by Greece's military government was followed by a Turkish military intervention, and the island was divided along a ceasefire line that is now a UN buffer zone. The Turkish Cypriot north declared independence as the TRNC in 1983.
A UN proposal to reunite Cyprus as a federation, put to separate referendums on 24 April 2004. About 65 per cent of Turkish Cypriots voted in favour and about 76 per cent of Greek Cypriots voted against, so it did not take effect.
The whole island is legally part of the EU, since the Republic of Cyprus joined in 2004, but EU law is suspended in the north because the Republic's government does not exercise effective control there. Turkish Cypriots who are Republic of Cyprus citizens are EU citizens.
Flights to Ercan airport generally route through Türkiye, and ferries run from Türkiye's southern coast. Many visitors fly to Larnaca or Paphos in the south and cross at one of the checkpoints. Rules for crossing and entry can change, so check official advice before travelling.
