French Mandate: Paulet–Newcombe Agreement '', October 25, 1920, reporting on the active discussions regarding the boundary line; this was later formalised in the
Paulet–Newcombe Agreement. The
Paulet–Newcombe Agreement, a series of agreements between 1920 and 1923, contained the principles for the boundary between the
Mandates of
Palestine and
Mesopotamia, attributed to Great Britain, and the Mandate of
Syria and the
Lebanon, attributed to France. A 1920 agreement defined the boundary between the forthcoming British and French mandates in broad terms, and placed the bulk of the Golan Heights in the French sphere. The agreement also established a joint commission to settle the border and mark it on the ground. several months before Britain and France assumed their Mandatory responsibilities on September 29, 1923. In this way the Golan Heights became part of the
French Mandate of Syria. When the French Mandate of Syria ended in 1944, the Golan Heights remained part of the newly independent state of Syria. and
Golan Heights, showing the Ottoman boundaries, the 1920 agreement and the 1923 agreement In 1923, an agreement between the United Kingdom and France, known as the
Paulet–Newcombe Agreement, established the border between the soon-to-be formalised territories covered by the British
Mandate for Palestine and the
French Mandate for Syria. The agreement added 227 square kilometers to the area of Palestine.
Syria: subsequent changes The
1947 UN Partition Plan allocated this territory to the Jewish state. Following the
1948 Arab–Israeli War, Syria seized some land that had been allocated to the Jewish state and under the
1949 Armistice Agreements with Israel retained 66 square kilometers of that territory in the Jordan Valley that lay west of the 1923 Palestinian Mandate border (marked green on Map 4). These territories were designated
demilitarized zones (DMZs) and remained under Syrian control (marked as DMZs on the map). It was emphasised that the armistice line was "not to be interpreted as having any relation whatsoever to ultimate territorial arrangements." (Article V) During the
Six-Day War (1967), Israel captured the territory as well as the rest of the Golan Heights, and subsequently repelled a Syrian attempt to recapture it during the
Yom Kippur War (1973). Israel annexed the Golan Heights in 1981 with the
Golan Heights Law. Israel began building
settlements throughout the Golan Heights, and offered the Druze and Circassian residents citizenship, which most turned down. Today, Israel regards the Golan Heights as its sovereign territory, and a strategic necessity. The
Purple Line marks the boundary between Israel and Syria. Israel's unilateral annexation has not been internationally recognized, and
United Nations Security Council Resolution 242 refers to the area as
Israeli-occupied. During the 1990s, there were constant negotiations between Israel and Syria regarding a mediation of conflicts and an Israeli withdrawal from the Golan Heights but a peace treaty did not come to fruition. The main stumbling block seems to involve the 66 square kilometers of territory that Syria retained under the 1949 armistice agreement. The area east of the Hasbani River is considered part of Syria and included in the Golan Heights. The armistice agreement between Lebanon and Israel was signed on March 23, 1949. The main points were: • The terms of the agreement were
dictated exclusively by military considerations. • The armistice line (i.e., "Green Line") was the international border, which corresponds to the 1923 Mandate border between the Lebanon and
Palestine (see:
Treaty of Sèvres). • Unlike the other Green Line agreements, it contains no clause disclaiming this line as an international border, and was thereafter treated as it had been previously, as the
de jure international border of Lebanon. • Israel withdrew its forces from 13 villages in Lebanese territory, which were occupied during the war. In 1923, 38 boundary markers were placed along the boundary and a detailed text description was published. The 2000 Blue Line differs in about a half dozen short stretches from the 1949 line, although never by more than . Between 1950 and 1967, Israeli and Lebanese surveyors managed to complete 25 non-contiguous kilometers and mark (but not sign) another quarter of the international border. The
Secretary-General reported to the
Security Council that Israel had withdrawn its forces from Lebanon on June 16, in accordance with Council Resolution 425, and met the requirements defined in his report of May 22, 2000. Since then, the term "Blue Line" has been the standard term for the withdrawal line in official UN communications.
Conflict over the Shebaa Farms The Shebaa Farms conflict stems from Israel's occupation and annexation of the Golan Heights, with respect to that territory's border with Lebanon. Both Lebanon and Syria were within the French Mandate territory between 1920 and the end of the French Mandate in 1946. The dispute over the sovereignty over the
Shebaa Farms resulted in part from the failure of French
Mandate administrations, and subsequently from the failure of the Lebanon and Syria to properly demarcate the border between them. Documents from the 1920s and 1930s indicate that some local inhabitants regarded themselves as part of Lebanon, for example paying taxes to the Lebanese government. But French officials at times expressed confusion as to the actual location of the border. One French official in 1939 expressed the belief that the uncertainty was sure to cause trouble in the future. The region continued to be represented in the 1930s and 1940s as Syrian territory, under the French Mandate. Detailed maps showing the border were produced by the French in 1933, and again in 1945. They clearly showed the region to be in Syria. After the French Mandate ended in 1946, the land was administered by Syria, and represented as such in all maps of the time. The maps of the 1949 armistice agreement between Syria and Israel also designated the area as Syrian. Border disputes arose at times, however. Shebaa Farms was not unique; several other border villages had similar discrepancies of borders versus land ownership. Syria and Lebanon formed a joint Syrian–Lebanese border committee in the late 1950s to determine a proper border between the two nations. In 1964, concluding its work, the committee suggested to the two governments that the area be deemed the property of Lebanon, and recommended that the international border be reestablished consistent with its suggestion. However, neither Syria nor Lebanon adopted the committee's suggestion, and neither country took any action along the suggested lines. Thus, maps of the area continued to reflect the Farms as being in Syria.
Israel—Lebanon maritime border As of April 2021, there was an ongoing dispute over the Mediterranean Sea border between Israel and Lebanon. Negotiations on the maritime border commenced in October 2020 and led to success, i.e. both sides reaching and ratifying an agreement in 2022.
2024 Israeli invasions of Lebanon and Syria Israeli invasions of Lebanon and Syria in 2024 have resulted in additional Lebanese and Syrian territory being occupied by Israeli forces. The Israeli military and Israeli settler movement has begun organizing trips for Israeli civilians inside the newly occupied part of Syria. ==Border with Egypt==
