On March 26, 1979, Egypt's president Anwar Sadat and Israel's prime minister Menachem Begin signed a peace treaty at the White House in Washington, D.C.. The President of the United States, Jimmy Carter, was also present. He had helped the relations between the countries. The treaty ended the war between Egypt and Israel. It included an agreement to end the conflict and three major points: the determination of final lines and zones, a promise of good relations between the two countries, and the problem of Palestinian autonomy. However, the problem of Palestinian autonomy remained unanswered.
