Egypt was involved in several wars against Israel and was allied with other Arab countries. The first was the 1948 Arab–Israeli War, right after the state of Israel was founded. Egypt went to war again in the Six-Day War of 1967 and lost the Sinai Peninsula to Israel. They went to war yet again in the Yom Kippur War of 1973. In 1979, President of Egypt Anwar Sadat and Prime Minister of Israel Menachem Begin signed the Camp David Accords, which gave back the Sinai Peninsula to Egypt in exchange for the recognition of Israel. The accords are still in effect today. In 1981, Sadat was assassinated by members of the Egyptian Islamic Jihad under Khalid Islambouli. The assassins were Islamists who targeted Sadat for his signing of the Accords.
