The Philadelphi Route, also called Philadelphia Corridor, refers to a narrow strip of land, 14 km (8.699 miles) in length, situated along the border between Gaza Strip and Egypt. Under the provisions of the Israeli-Egyptian peace treaty of 1979, it was established as a buffer zone controlled and patrolled by Israeli forces. One purpose of the Philadelphi Route was to prevent the movement of illegal materials (including weapons and ammunition) and people between Egypt and the Gaza Strip. Palestinians, in cooperation with some Egyptians, have built smuggling tunnels under the Philadelphi Route to move these into the Gaza Strip.
After the 1995 Oslo Accords, Israel was allowed to retain the security corridor. Following Israel's unilateral disengagement from the Gaza-strip in 2005, the Philadelphi Accord with Egypt was concluded, which authorized Egypt to deploy 750 border guards along the route to patrol the border on Egypt's side. The Palestinian side of the border was controlled by Palestinian Authority, until the 2007 takeover by Hamas. The joint authority for the Rafah border crossing was transferred to the Palestinian Authority and Egypt for restricted passage by Palestinian ID card holders, and by others by exception.
The 1979 Egypt-Israel Peace Treaty, in which Israeli agreed to withdraw from the Sinai in exchange for peace with Egypt, stipulated that the border with Egypt would follow the border of Mandatory Palestine. The new border cut across Rafah, dividing the town and leaving families separated on both sides of the border. Rafah would be the main border crossing in Gaza. It was agreed that the area near the border (known as Area C) would be demilitarized, with Egypt only permitted to maintain police forces there.
