Wars

The Arab- Israeli War of 1948

After Israel declared its independence on May 14, 1948, the fighting intensified with other Arab forces joining the Palestinian Arabs in attacking territory in the former Palestinian area. Despite help for resolution by the UN the fighting continued into 1949. Israel and the Arab states did not reach any formal armistice agreements until February. Under separate agreements between Israel and the neighboring states, the bordering nations agreed to formal armistice lines. Israel gained some territory formerly granted to Palestinian Arabs under the United Nations resolution in 1947. This armistice held until 1967.
