The State of Israel was established on 14 May, 1948 by the Israeli Declaration of Independence. They became a member of the United Nations on 11 May, 1949. 
85% of UN members recognise Israel. However, many countries (mostly those in the Muslim world) do not recognise Israel because of the Arab–Israeli conflict, especially the Israeli–Palestinian conflict.
