The “green line” is the border that defines the area called the “West Bank”. This line was the 1949 cease-fire line which ended hostilities after the declaration of the state of Israel in May 1948. The State was declared pursuant to the UN vote in favour of partition in Nov. 1947, but was immediately attacked by the surrounding Arab countries. The area called the West Bank was captured by Israel in the 1967 Six Day War and comprises all the land noted in these maps having a reddish tint up to the Jordanian border.

A large part of the “green line” parallels the coast of Israel, leaving over 70% of the population confined in a narrow strip of as little as 9 miles(14km). The major population centers are only 9 to 14 miles(14-22km) from the green line.

To give you a visual perspective on what this means, we have maps that
compare Israel to many well-known cities across the globe.
