In protest against the Balfour Declaration , which proposed Palestine as a homeland for the Jewish people , and its implementation under a League of Nations Mandate for Great Britain , Palestinians , both Muslim and Christian , from November 1918 onwards , began to organize in opposition to Zionism . By the end of Ottoman rule , the Jewish population of Palestine was 56,000 or one-sixth of the population . Hostility to Jewish immigration led to incidents , such as the riots of April 1920 , the Jaffa riots of 1921 , the 1929 Palestine riots , until a general Arab revolt broke out for three years , in 1936 – 1939 , which was crushed , with the loss of 5,000 lives , by the British army . After the passing of the United Nations Partition Plan for Palestine in 1947 which called for the establishment of independent Arab and Jewish States , a Palestinian Civil War broke out . On the declaration of the state of Israel , 15 May 1948 , a full-scale war , involving also the intervention of neighbouring Arab states , took place , with casualties of 6,000 Israelis and , according to the 1958 survey by Arif al-Arif , 13,000 Palestinians and the exodus , through expulsion , or panicked flight , of approximately 700,000 Arab Palestinians who subsequently became refugees . In the Six-Day War , a further 280,000 – 360,000 Palestinians became refugees , and the remaining Palestinian territories were also occupied from Jordan and from Egypt , and later began to be settled by Jewish and Israeli settlers , while the Palestinians were placed under military administration . While historically , Palestinian militancy was fragmented into several groups , the PLO led , and eventually united , most factions , while conducting military campaigns that varied from airplane hijackings , militant operations and civil protest . In 1987 , a mass revolt , of predominantly civil resistance , called the First Intifada , exploded , leading to the Madrid Conference of 1991 , and subsequently to the Oslo I Accord , which produced an interim understanding allowing a new Palestinian authority , the Palestinian National Authority ( PNA ) to exercise limited autonomy in 3 % ( later 17 % ) of the West Bank , and parts of the Gaza Strip not used or earmarked for Israeli settlement . Frustration over the perceived failure of the peace talks to yield a Palestinian state led to the outbreak of the Al Aqsa Intifada in September 2000 , which ended in 2005 , coincident with the Israeli withdrawal from Gaza . The rise of Hamas , the use of Palestinian rocketry and Israel 's control of Gaza 's borders , has led to further chronic violence , culminating in a further two conflicts , the Gaza War of 2008 – 09 and Operation Pillar of Defense in 2012 . It is estimated that since 1920 , when the first riots against Jews broke out , 90,785 Arabs including Palestinians have died , and some 67,602 been wounded in all wars and conflicts between Israel and its neighbors . On the other hand , 24,841 Jews and Israelis have died and 35,356 have been wounded during the same period . Since 1967 , some reports estimate that some 40 % of the male population of the West Bank and Gaza have been arrested or detained in Israeli prisons for political or military reasons
