Israel's borders

The current borders of the State of Israel are the result both of war and of diplomatic agreements among Israel, her neighbors, and colonial powers. Some borders are internationally recognized while others are disputed.

According to interpretations of the Green Line of the 1949 Armistice Agreements, Israel borders Lebanon in the north, the Golan Heights and Syria in the northeast, the West Bank and Jordan in the east, the Gaza Strip and Egypt in the southwest. The border with Egypt is the international border demarcated in 1906 between United Kingdom and the Ottoman Empire.

The borders with Lebanon, Syria and Jordan are based on those drawn by the United Kingdom and France in anticipation of the defeat of the Ottoman Empire in the First World War and the subsequent partition of the Ottoman Empire's Middle East provinces between them. Finalized in subsequent agreements, these borders are referred to as the 1923 Paulet-Newcombe Agreement borders and were those of the British Mandate of Palestine.

Israel's borders with Egypt and Jordan have now been formally recognized and confirmed as part of the peace treaties with those countries, and with Lebanon as part of the 1949 Armistice Agreements. As of 2002, the borders with Syria and Palestinian National Authority were still in dispute.

The Sykes–Picot Agreement of 1916 secretly divided the Ottoman Empire lands of Middle East between British and French spheres of influence. They agreed that "Palestine" was to be designated as an "international enclave".
