Muhammad Anwar el-Sadat was an Egyptian politician who served as the third President of Egypt, from 15 October 1970 until his assassination by fundamentalist army officers on 6 October 1981. 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 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.
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.
