Israel /ˈɪzreɪəl/, officially the State of Israel, is a country in Western Asia, on the south-eastern shore of the Mediterranean Sea. It shares land borders with Lebanon in the north, Syria in the northeast, Jordan on the east, the Palestinian territories comprising the West Bank and Gaza Strip on the east and southwest respectively, Egypt and the Gulf of Aqaba in the Red Sea to the south, and it contains geographically diverse features within its relatively small area. In its Basic Laws Israel defines itself as a Jewish and Democratic State; it is the world's only Jewish-majority state.On 29 November 1947, the United Nations General Assembly recommended the adoption and implementation of the partition plan of Mandatory Palestine. On 14 May 1948, David Ben-Gurion, the Executive Head of the World Zionist Organization and president of the Jewish Agency for Palestine, declared "the establishment of a Jewish state in Eretz Israel, to be known as the State of Israel," a state independent upon the termination of the British Mandate for Palestine, 15 May 1948. Neighboring Arab armies invaded Palestine on the next day and fought the Israeli forces. Israel has since fought several wars with neighboring Arab states, in the course of which it has occupied the West Bank, Sinai Peninsula, part of South Lebanon, Gaza Strip and the Golan Heights. It annexed portions of these territories, including East Jerusalem, but the border with the West Bank is disputed. Israel has signed peace treaties with Egypt and Jordan, but efforts to resolve the Israeli–Palestinian conflict have so far not resulted in peace.Israel's financial center is Tel Aviv, while Jerusalem is the country's most populous city and its designated capital, though internationally Jerusalem is not considered to be a part of Israel.Ethnic groups in Israel include Mizrahi Jews, Ashkenazi Jews, Palestinians, Sephardi Jews, Yemenite Jews, Ethiopian Jews, Bedouin, Druze, and many other groups.
