Israel-Palestine or How it started

1917: After the victory of the Arabs against the Ottomans, the Arabs aim for their independence. However, Britain does not have the same opinion and promises the Zionists a homeland in Palestine which will be occupied after a year.

1920: Under the Treaty of Versailles (1919), Great Britain took over the administration of Israel, ignoring the Arabs. The migration of Jews begins, an army is created and in the same time they want to establish a legislative council (consisting of Arabs and Jews) but they fail due to reactions.

1929: The Arabs revolt and kill 130 people. Britain responds by restricting the entry of Jews but soon fails and resigns.
Τhe conflicts escalated until 1936, when regular armed battles broke out between Arabs and Jews with British tolerance.

1937: Britain announces plan to "divide" the Holy Land between Jews and Arabs in the same time an increasing number of Jews are flocking to Palestine because of Nazi persecution.

1944: The Jewish organization "Irgun", led by the later Israeli Prime Minister Menehem Begin, declares war on the British.

1947: The UN decides to divide Palestine (Jewish State 55%, Palestinian State 43%, Jerusalem International City). The Arabs refuse, and as troops gather around Jewish settlements, Ben Gurion declares Israel independence in 1948. The first Arab-Israeli war ensues, in which the Israelis win and about 750,000 Palestinians are displaced.
 
1956:Egyptian leader, Nasser, nationalizes the Suez Canal as result France, Israel and Britain answer with a coordinated attack. The United States is taking Egypt's side and forced them to retreat. In this way, the United States is gaining the role of "regulator" of the region, a role that until then was played by Great Britain.

1967-68: New war starts and lasts just six days and resulting in the crushing of the Arabs and the more than doubling of Israel's territory. The UNO reacted by issuing Resolution 242, which provides for the immediate withdrawal of Israelis from the occupied territories. The implementation of this resolution is still pending.
 The Palestine Liberation Organization, founded in 1964, propose a constitution and call for the immediate establishment of a Palestinian state. The following year, Fatah leader Yasser Arafat was elected leader of the organization.

1987: The first Intifada breaks out. The "Hamas" ("Islamic Resistance Movement") is founded, the Palestinian organization that, in the coming years, will play a leading role in the Israeli-Palestinian conflict.

1993: The Oslo Agreement is signed between the PLO and the State of Israel between the leaders of the two parties, Yitzhak Rabin and Yasser Arafat, under the auspices of US President Bill Clinton. It is decided to withdraw Israel’s troops from the West Bank and Gaza Strip and the right of the Palestinians to control their own home is recognized, with the creation of the Palestinian Authority.
