Bird's-eye View Of Jerusalem, Israel

On May 14, 1948, the day before the expiration of the British Mandate, the Jewish Agency proclaimed independence, naming the country Israel. The following day, the armies of four Arab countries—Egypt, Syria, Lebanon and Iraq—attacked Israel, launching the 1948 Arab–Israeli War; Saudi Arabia sent a military contingent to operate under Egyptian command; Yemen declared war but did not take military action. After a year of fighting, a ceasefire was declared and temporary borders, known as the Green Line, were established. Jordan annexed what became known as the West Bank and East Jerusalem, and Egypt took control of the Gaza Strip. About 700,000 Palestinian refugees were expelled or fled the country during the conflict.
Israel was accepted as a member of the United Nations by majority vote on May 11, 1949.
In the early years of the state, the Labor Zionist movement led by Prime Minister David Ben-Gurion dominated Israeli politics. These years were marked by an influx of Holocaust survivors and Jews from Arab lands, many of whom faced persecution in and expulsion from their original countries. Consequently, the population of Israel rose from 800,000 to two million between 1948 and 1958. Most arrived as refugees with no possessions and were housed in temporary camps known as ma'abarot; by 1952, over 200,000 immigrants were living in these tent cities. The need to solve the crisis led Ben-Gurion to sign a reparations agreement with West Germany that triggered mass protests by Jews angered at the idea of Israel accepting financial compensation from Germany for the Holocaust.
