A buffer zone in Cyprus was first established in the last days of 1963, when Major-General
Peter Young was the commander of the British Joint Force (later known as the Truce Force and a predecessor of the present UN force). This Force was set up in the wake of the
intercommunal violence of Christmas 1963. On 30 December 1963, following a 'high powered' twelve hour meeting chaired by
Duncan Sandys (British Secretary of State for Commonwealth Relations), General Young drew the agreed cease-fire line on a map with a green
chinagraph pencil, which was to become known as the "Green Line".
Brigadier Patrick Thursby also assisted in devising and establishing the Green Line. This map was then passed to General Young's intelligence officer, who was waiting in a nearby building and told to "Get on with it." Intelligence Corps NCOs then copied the map for distribution to the Truce Force units. Further copies of the map would then have been produced 'in house' for use by Truce Force patrols. The Green Line became impassable following the July 1974
Turkish invasion of Cyprus during which Turkey occupied approximately 37% of Cypriot territory, in response to a short-lived
Greek Cypriot coup. A "security zone" was established after the Tripartite Conference of
Geneva in July 1974. Pursuant to
United Nations Security Council Resolution 353 of 1974, the foreign ministers of Greece, Turkey, and the United Kingdom convened in
Geneva on 25 July 1974. According to UNFICYP, the text of the joint declaration transmitted to the
Secretary-General of the United Nations was as follows: The UN Security Council then adopted the above declaration with
Resolution 355. When the coup dissolved, the
Turkish Armed Forces advanced to capture approximately 37% of the island and met the "Green Line". The
meandering Buffer Zone marks the southernmost points that the Turkish troops occupied during the
Turkish Invasion of Cyprus in August 1974, running between the
ceasefire lines of the
Cypriot National Guard and Turkish army that
de facto divides Cyprus into two, cutting through the capital of
Nicosia. With the
self-proclamation of the internationally unrecognized "Turkish Republic of Northern Cyprus", the Buffer Zone became its de facto southern border. Traffic across the buffer zone was very limited until 2003, when the number of crossings and the rules governing them were relaxed. In March 2021
Cyprus erected a barbed wire fence on the Buffer Zone to curb illegal immigration. ==Sectors==
