FACTBOX-Arab-Israeli conflict of 1948

May 14 (Reuters) - U.S. President George W. Bush arrived in Israel on Wednesday to mark the 60th anniversary of the Jewish state as Palestinians mourn the "Nakba", or catastrophe, of 1948 when half the Arabs of Palestine were driven from their homes.

Israel has roots in the 19th-century Zionist response to Jewish persecution in Europe -- a state on land Jews say God gave to them. Arabs say Western imperial powers supported ethnic cleansing of Palestinians to answer European Jewish aspirations.

When World War One ended Ottoman Turkish control, the League of Nations gave Britain the Palestine Mandate in 1920, endorsing its Balfour Declaration to create "a national home for the Jewish people" and to protect the rights of Arabs.

In 1948, Palestine had 1.4 million Arabs and 720,000 Jews. Two thirds of these were born abroad, notably in eastern Europe.

Following is a brief chronology of how the land was divided:

Nov. 29, 1947 - United Nations General Assembly agrees plan for partition into Arab and Jewish states and for international rule over Jerusalem. Jewish leaders accept plan that gives them 56 percent of Palestine land. Arab League rejects the proposal.

Jan. 10, 1948 - British report to U.N. says 1,974 people killed or wounded in violence by both sides since Nov. 30.

April 9-10 - After Jewish guerrillas launch major push into Arab-designated areas, Jewish gunmen kill more than 100 Arab men, women and children -- many more by some estimates -- at Deir Yassin near Jerusalem. Word of massacre fuels Arabs' fears.

April 13 - As tens of thousands of Arabs flee mounting violence, Arab forces kill 79 Jews in Jerusalem hospital convoy.

June 30 - Last British troops leave.

March 10 - Israeli forces take Umm Rashrash (now Eilat), near Jordanian port of Aqaba, giving Israel access to Red Sea.

July 20 - Israel-Syria armistice ends war. Israelis control 78 percent of Palestine, including West Jerusalem and about half the area designated for an Arab state under U.N. plan. Jordan occupies West Bank and East Jerusalem, Egypt holds Gaza Strip.
