Muhammad Anwar el-Sadat (25 December 1918 – 6 October 1981) was the third President of Egypt, serving from 15 October 1970 until his assassination by fundamentalist army officers on 6 October 1981. He initiated serious peace negotiations with Israel, an achievement for which he shared the 1978 Nobel Prize for Peace with Israeli Prime Minister Menachem Begin. Under their leadership, Egypt and Israel made peace with each other in 1979.
Sadat was a senior member of the Free Officers who overthrew King Farouk 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 his eleven years as president, he changed Egypt's trajectory, departing from many of the political and economic tenets of Nasserism, re-instituting a multi-party system, and launching the Infitah economic policy. As President, he led Egypt in the Yom Kippur War of 1973 to regain Egypt's Sinai Peninsula, which Israel had occupied since the Six-Day War of 1967, making him a hero in Egypt and, for a time, the wider Arab World. Afterwards, he engaged in negotiations with Israel, culminating in the Egypt–Israel Peace Treaty; this won him and Israeli Prime Minister Menachem Begin the Nobel Peace Prize, making Sadat the first Muslim Nobel laureate. Though reaction to the treaty—which resulted in the return of Sinai to Egypt—was generally favorable among Egyptians, it was rejected by the country's Muslim Brotherhood, which felt Sadat had abandoned efforts to ensure a Palestinian state. With the exception of Sudan, the Arab world and the Palestine Liberation Organization (PLO) strongly opposed Sadat's efforts to make a separate peace with Israel without prior consultations with the Arab states. His refusal to reconcile with them over the Palestinian issue resulted in Egypt being suspended from the Arab League from 1979 to 1989. The peace treaty was also one of the primary factors that led to his assassination.
