The Bar-Lev Line was a chain of fortifications built by Israel along the eastern bank of the Suez Canal shortly after the 1967 Arab–Israeli War, during which Egypt lost the entire Sinai Peninsula. It was considered impenetrable by the Israeli military until it was overrun in less than two hours during Egypt's Operation Badr, which sparked the 1973 Arab–Israeli War.

The Sinai Peninsula, or simply Sinai, is a peninsula in Egypt, and the only part of the country located in Asia. It is between the Mediterranean Sea to the north and the Red Sea to the south, and is a land bridge between Asia and Africa. Sinai has a land area of about 60,000 km2 (23,000 sq mi) and a population of approximately 600,000 people. Administratively, the vast majority of the area of the Sinai Peninsula is divided into two governorates: the South Sinai Governorate and the North Sinai Governorate. Three other governorates span the Suez Canal, crossing into African Egypt: Suez Governorate on the southern end of the Suez Canal, Ismailia Governorate in the center, and Port Said Governorate in the north.
