er as President in June, 1956. British forces completed their withdrawal from the occupied Suez Canal Zone on 13 June 1956. He nationalized the Suez Canal on 26 July 1956, prompting the 1956 Suez Crisis.
In the 1967 Six Day War, Israel invaded and occupied Egypt's Sinai Peninsula and the Gaza Strip, which Egypt had occupied since the 1948 Arab–Israeli War. Three years later President Nasser died and was succeeded by Anwar Sadat in 1970. Sadat switched Egypt's Cold War allegiance from the Soviet Union to the United States, expelling Soviet advisors in 1972. He launched the Infitah economic reform policy, while clamping down on religious and secular opposition.
In 1973, Egypt, along with Syria, launched the October War, a surprise attack against the Israeli forces occupying the Sinai Peninsula and the Golan Heights. It was an attempt to regain part of the Sinai territory Israel had captured 6 years earlier. Sadat hoped to seize some territory through military force, and then regain the rest of the peninsula by diplomacy. The conflict sparked an international crisis between the US and the USSR, both of whom intervened. The second UN-mandated ceasefire halted military action. While the war ended with a military stalemate, it presented Sadat with a political victory that later allowed him to regain the Sinai in return for peace with Israel.
Sadat made a historic visit to Israel in 1977, which led to the 1979 peace treaty in exchange for Israeli withdrawal from Sinai. Sadat's initiative sparked enormous controversy in the Arab world and led to Egypt's expulsion from the Arab League, but it was supported by most Egyptians. A fundamentalist military soldier assassinated Sadat in Cairo in 1981. He was succeeded by Hosni Mubarak.
In 2003, the Egyptian Movement for Change, popularly known as Kefaya, was launched to oppose the Mubarak regime and to establish democratic reforms and greater civil liberties
