Muhammad Anwar El Sadat 1918 -1981) was the third President of Egypt, serving from 1970 until his assassination by fundamentalist army officers in 1981. As President, he led Egypt in the Yom Kippur War of 1973 with Israel to regain Egypt’s Sinai Peninsula (which Israel had captured in the Six-Day War of 1967). 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 and leftists in particular. The peace treaty was considered one of the primary factors that led to his assassination.
