Israel–Syria border

A mandate line and an armistice

After the First World War the Golan became part of the French mandate of Syria, and it passed to independent Syria in 1941.^[1] To the west lay Palestine, and the line between them is what the 1949 armistice calls “the international boundary between Syria and Palestine”.^[3]

After the 1948–49 war, Israel and Syria signed a General Armistice Agreement on 20 July 1949. It drew an armistice line between the two armies and said it had no bearing on the final territorial settlement. Wherever the line differed from the old international boundary between Syria and Palestine, the land in between became a demilitarised zone.^[3] Syria fortified the western crest of the Golan, which overlooks the Hula Valley and the Sea of Galilee, and Israeli civilians below were often under fire.^[1]

“the area between the Armistice Demarcation Line and the boundary, pending final territorial settlement between the Parties, shall be established as a Demilitarized Zone”^[3]

1967, 1973 and the 1974 line

On the last two days of the Six-Day War, 9–10 June 1967, Israeli forces stormed the Golan Heights. Most of the Arab inhabitants fled, and fighting stopped on 10 June. Five mainly Druze villages remained. Their people were offered Israeli citizenship, and most declined.^[1]

War broke out again on the Golan in October 1973. A US diplomatic effort then produced a disengagement agreement, signed on 31 May 1974, with an area of separation between the two forces and zones of limited forces on each side.^[2] The same day the UN Security Council set up the UN Disengagement Observer Force (UNDOF) to watch it.^[2] Israel holds almost all of the Golan, up to the June 1967 ceasefire line as modified in 1974.^[1]

Annexation, and who recognises it

In December 1981 Israel annexed the part of the Golan it held, imposing its own law there.^[1][4] On 17 December the Security Council unanimously adopted resolution 497, which called the decision “null and void and without international legal effect”.^[4]

Talks that began in Madrid in 1991 broke down in 2000 over Syria’s demand for a full Israeli withdrawal, and talks mediated by Turkey in 2008 ended when Israeli Prime Minister Ehud Olmert resigned.^[1] In 2019 the United States became the first country to recognise Israeli sovereignty over the Golan, and in 2026 Colombia became the second.^[1]

“Decides that the Israeli decision to impose its laws, jurisdiction and administration in the occupied Syrian Golan Heights is null and void and without international legal effect”^[4]

After Assad

On 7 December 2024, as President Bashar al-Assad’s government collapsed, Israeli forces entered the UN buffer zone. Israeli officials said the move was temporary, meant to keep Syria’s turmoil from spilling over; officials in Arab countries and many observers feared Israel was using the moment to take land. The following week Israel’s government approved plans to double the number of Israelis living on the Golan.^[1]
