evidence: An armistice line that in 1949 formed the de facto border between Israel and what was left of historic Palestine The Green Line is a term that emerged in the wake of Israel’s establishment in 1948, whose proper name is the 1949 Armistice Line. It refers to the border separating pre-1967 Israel from the Occupied Palestinian Territories, and constitutes an internationally recognised border. However, it is important to note that Israel has never specified the boundaries of its own state. MORE ABOUT "GREEN LINE"
