"The majority of the approximately 750,000 people in this multi-ethnic region were Arabic-speaking Muslims, including a Bedouin population (estimated at 103,331 at the time of the 1922 census [2] and concentrated in the Beersheba area and the region south and east of it), as well as Jews (who comprised some 11% of the total) and smaller groups of Druze, Syrians, Sudanese, Circassians, Egyptians, Greeks, and Hejazi Arabs.

In June 1922 the League of Nations passed the Palestine Mandate. The Palestine Mandate was an explicit document regarding Britain's responsibilities and powers of administration in Palestine including "secur[ing] the establishment of the Jewish national home", "

"In 1936-1939 the mandate experienced an upsurge in militant Arab nationalism that became known as the Great Uprising and, "The Arab Revolt." The revolt was triggered by increased Jewish immigration, primarily Jews that were ejected by the Nazi regime in Germany as well as rising anti-Semitism throughout Europe. The revolt was led or co-opted by the Grand Mufti, Haj Amin Al-Husseini and his Husseini family. The Arabs felt they were being marginalized in their own country, but in addition to non-violent strikes, they resorted to violence. Husseini's men killed more Arabs than Jews, using the revolt as an excuse to settle accounts with rival clans. The Jewish organization Etzel replied with its own terrorist campaign, with marketplace bombings and other violent acts that also killed hundreds. Eventually, the uprising was put down by the British using severe measures. After he was implicated in killing the British district commissioner for the Galilee, Haj Amin El Husseini fled first to Lebanon, then to Iraq, and finally to Germany in late 1941.

The British placed restrictions on Jewish land purchases in the remaining land, directly contradicting the provision of the Mandate which said "the Administration of Palestine... shall encourage, in cooperation with the Jewish Agency... close settlement by Jews on the land, including State lands and waste lands not acquired for public purposes." A similar proposal to limit immigration in 1931 had been termed a violation of the mandate by the League of Nations, but by 1939 the League of Nations was defunct. According to the Israeli side, the British had by 1949 allotted over 8500 acres (34 km²) to Arabs, and about 4000 acres (16 km²) to Jews."
