Definitions for "Green Line"
The "border" separating pre-1967 Israel from the West Bank.
This was the demarcation between the 1967 borders of Israel and the West Bank territories captured in the defensive Six-Day War. Although usually referred to as the "1967 border," it actually is the 1949 armistice line, as there was no internationally recognized border at the time. The reference came about because someone used a green pen on the map of the armistice agreement with Jordan to draw the border.
the border marking the boundaries of the land that Israel won in its 1948 war of independence
