Egyptian president Anwar Sadat (pictured) was assassinated while attending a parade in Cairo to mark the eighth anniversary of the Crossing of the Bar Lev Line at the start of the 1973 Arab-Israeli War.

Muhammad Anwar es-Sadat was an Egyptian politician and military officer who served as the third president of Egypt, from 15 October 1970 until his assassination by members of the Islamic Jihad on 6 October 1981. Sadat was a senior member of the Free Officers who overthrew King Farouk I in the Egyptian Revolution of 1952, and a close confidant of President Gamal Abdel Nasser, under whom he served as vice president twice and whom he succeeded as president in 1970. In 1978, Sadat and Menachem Begin, Prime Minister of Israel, signed a peace treaty in cooperation with United States President Jimmy Carter, for which they were recognized with the Nobel Peace Prize.

Operation Badr, also known as Plan Badr, was an Egyptian military offensive and operation across the Suez Canal that destroyed the Bar-Lev Line, a chain of Israeli fortifications along the frontline of the Israeli-occupied Sinai Peninsula, on 6 October 1973. It was launched in conjunction with a Syrian military offensive against the Israeli-occupied Golan Heights, triggering the Yom Kippur War. During the War of Attrition, which preceded Operation Badr, both Egypt and Syria had been seeking to recover the territories that Israel had captured from them during the 1967 Arab–Israeli War.

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 Yom Kippur War.

The Yom Kippur War, also known as the 1973 Arab–Israeli War, the fourth Arab–Israeli War, the October War, or the Ramadan War, was fought from 6 to 25 October 1973 between Israel and a coalition of Arab states led by Egypt and Syria. Most of the fighting occurred in the Sinai Peninsula and Golan Heights, territories occupied by Israel in 1967. Some combat also took place in mainland Egypt and northern Israel. Egypt aimed to secure a foothold on the eastern bank of the Suez Canal and use it to negotiate the return of the Sinai Peninsula.
