The assassination of Anwar Sadat occurred on 6 October 1981. Anwar Sadat, the President of Egypt, was assassinated during the annual victory parade held in Cairo to celebrate Operation Badr (1973), during which the Egyptian Army had crossed the Suez Canal and taken back a small part of the Sinai Peninsula from Israel at the beginning of the Yom Kippur War. A fatwā approving the assassination had been obtained from Omar Abdel-Rahman, a cleric later convicted in the US for his role in the 1993 World Trade Center bombing.The assassination was undertaken by members of the Egyptian Islamic Jihad.
Following the Camp David Accords, Sadat and Israeli Prime Minister Menachem Begin shared the 1978 Nobel Peace Prize. But the subsequent 1979 Egypt–Israel Peace Treaty was received with controversy among Arab nations, particularly the Palestinians. Egypt's membership in the Arab League was suspended (and not reinstated until 1989). PLO Leader Yasser Arafat said "Let them sign what they like. False peace will not last." In Egypt, various jihadist groups, such as the Egyptian Islamic Jihad and the al-Gama'a al-Islamiyya, used the Camp David Accords to rally support for their cause. Previously sympathetic to Sadat's attempt to integrate them into Egyptian society, Egypt's Islamists now felt betrayed and publicly called for the overthrow of the Egyptian president and the replacement of the nation's system of government with a government based on Islamic theocracy.
