evidence: The Green Line refers to the line of demarcation that separated Israeli, Jordanian, Syrian and Egyptian forces at the conclusion of Israel’s 1948 War of Independence. It was delineated in the 1949 armistice agreements that formally ended the war and served as Israel’s de facto international border until the 1967 Six-Day War. Its name derives from the fact that the diplomats drawing up the agreement reportedly used green ink to mark the line on the map. During the 1967 war, Israel vastly increased the territory under its control, taking possession of the West Bank, the Gaza Strip and the Sinai peninsula. The Green Line thus came to mark the border between Israel and the territories it captured in the war. As a result, the Green Line is sometimes referred to as the "pre-1967 border," though it was never intended to mark a recognized international boundary between Israel and its neighbors. As the border between Israel and the West Bank remains the only boundary whose precise route remains in substantial dispute, the Green Line is most commonly used today to refer to the dividing line between those territories.
