The 1948 War which is also the very First Arab–Israeli War. Was the second and final stage of the 1947– 49 Palestine war. The War Officially began after David Ben Gurion, Israel’s first Prime Minister declared the State of Israel in May 15th, 1948.

The 1948 War – A Clash Bound to Happen
In more ways than one, the 1948 war was inevitable. A struggle between two distinct nations that claim ownership of a tiny piece of land probably wouldn’t end well. The civil war between the local Arabs (Palestinians) in November 1947 escalated to a full-blown regional war. Between a state born to an Arab coalition of five invading armies. The roots of the conflict go back to the late 19th century when waves of Jews immigrants returned to their homeland. The conflict escalated as more and more Jews came. It began as local clashes between remote Jewish colonies with their Arab neighbors across the valley. Sometimes shots were fired over a cow that got stolen. Perhaps even violent disputes about where I can plow or where my cattle can freely graze.

Arab opposition developed into the 1936–1939 Arab revolt in Palestine; while the Jewish resistance developed into the 1944–1947 Jewish insurgency in Palestine. In 1947, these ongoing tensions erupted into civil war following the 29 November 1947 adoption of the United Nations Partition Plan for Palestine; which planned to divide Palestine into an Arab state, a Jewish state, and the Special International Regime encompassing the cities of Jerusalem and Bethlehem.
The 1948 War: The Declaration of Independence of the State of Israel

On 15 May 1948, the civil war transformed into a conflict between Israel and the Arab states following the Israeli Declaration of Independence the previous day. Egypt; Transjordan; Syria, and expeditionary forces from Iraq entered Palestine. The invading troops took control of the Arab areas and immediately attacked Israeli forces and several Jewish settlements. The ten months of the fighting took place mainly on the territory of the British Mandate and in the Sinai Peninsula and southern Lebanon, interrupted by several truce periods.
As a result of the 1948 War, the State of Israel controlled the area that UN General Assembly Resolution 181 had recommended for the proposed Jewish state, as well as almost 60% of the area of the Arab state proposed by the 1947 Partition Plan, including the Jaffa; Lydda, and Ramle area, Galilee; some parts of the Negev; a wide strip along the Tel Aviv–Jerusalem road, West Jerusalem, and some territories in the West Bank. Transjordan took control of the remainder of the former British mandate, which it annexed, and the Egyptian military took control of the Gaza Strip.
The conflict triggered significant demographic change throughout the Middle East. Around 700,000 Palestinian Arabs fled or were expelled from their homes in the area that became Israel, and they became Palestinian refugees in what they refer to as Al-Nakba (“the catastrophe”). In the three years following the war, about 700,000 Jews emigrated to Israel. Around 260,000 Jews moved to Israel from the Arab world during and immediately after the war.
