1978 - Camp David Accords
In early September 1978, President Jimmy Carter invited Muhammad Anwar al-Sadat, the President of the Arab Republic of Egypt, and Menachem Begin, the Prime Minister of Israel to meet at Camp David, Maryland, to discuss peace between the two countries. The outcome of this historic meeting were two documents. The Framework for Peace in the Middle East established an autonomous sel-governing authority in the West Bank and Gaza Strip and oulined principles of negotiation between Israel and its Arab neighbors. The Framework for the Conclusion of a Peace Treaty between Egypt and Israel presented plans for Israeli withdrawl from Sinai and and input into the number of military forces Egypt could place in the area. These two documents have helped form Middle Eastern policy ever since.
