Why did the 1947 United Nations Partition Plan for Palestine divide the land the way it did?

By February 1947, Britain had spent twenty-five years administering Palestine under a League of Nations mandate, and the situation had become largely unmanageable.

Jewish paramilitary organisations included the Irgun and Lehi, and these groups had intensified their campaign of violence against British targets, as the British continued to enforce the 1939 White Paper that severely restricted Jewish immigration.

At the same time, hundreds of thousands of Jewish refugees who were in displaced persons camps across Europe were desperate to enter Palestine, and American President Harry Truman was pressuring London to admit at least 100,000 of them.

For British Foreign Secretary Ernest Bevin, the costs of maintaining the mandate had become politically unsustainable. Britain announced in February 1947 that it intended to end the mandate and referred the question to the United Nations, which had recently been established.

As the historian William Roger Louis has noted, Bevin expected an Arab majority in the General Assembly to block any partition proposal, which would have preserved British influence in the region.

That calculation ultimately proved to be wrong.

In May 1947, the General Assembly created the United Nations Special Committee on Palestine (UNSCOP) and appointed representatives from eleven countries that were drawn from across the globe.

The committee’s task was to travel to Palestine and investigate conditions on the ground, as well as recommend a political solution.

During their visit in August 1947, UNSCOP members witnessed the SS Exodus affair firsthand: a ship that carried over 4,500 Jewish refugees from Europe was forcibly turned back by the British navy at Haifa port.

The incident reportedly made a powerful impression on the delegates, because it exposed the human cost of British immigration restrictions.

UNSCOP also sent a subcommittee to visit Jewish displaced persons camps in Europe, where members observed the scale of post-Holocaust displacement.

After three months of investigation, UNSCOP delivered its report on 3 September 1947.

The committee produced two competing proposals. A majority plan was supported by seven nations, which included Canada and Sweden, and it recommended partition into two independent states that were joined by an economic union.

A minority plan was backed by India and Iran along with Yugoslavia and proposed a single federal state that contained both Jewish and Arab constituent regions.

The General Assembly chose to pursue the majority plan.

Since the plan needed to create a viable Jewish state that was capable of absorbing future immigration, UNSCOP drew boundaries according to two primary considerations: where Jewish populations were concentrated and where land existed for future settlement.

Jewish communities in 1947 were concentrated along the coastal plain from Haifa to Rehovot and in the eastern Galilee around the Sea of Galilee, as well as in scattered agricultural settlements across the Negev desert.

As a result of these settlement patterns, the proposed Jewish state consisted of three barely adjoining sections that were connected by narrow crossing points.

The coastal strip included the major cities of Haifa and Tel Aviv, along with the fertile lowland plains that Jewish settlers had developed since the early twentieth century.

The eastern Galilee section included the Sea of Galilee, which was essential for the Jewish state’s water supply.

The Negev desert made up roughly 60 percent of the proposed Jewish state’s territory and was largely arid and unsuitable for agriculture at the time, but it provided access to the Red Sea port at Umm Rashrash (now Eilat) and offered space for the wave of immigration that was anticipated.

The proposed Arab state received approximately 43 percent of Mandate Palestine, which included the western Galilee down to Acre, the central highlands around Nablus and Hebron, the southern coastal strip that is now the Gaza Strip, and the town of Jaffa, which was designated as an Arab enclave within the Jewish state.

Of the sixteen districts in Mandate Palestine, nine were allocated to the Jewish state, but only one of those nine actually had a Jewish majority.

The proposed Jewish state would have contained approximately 498,000 Jews alongside 325,000 Arabs, which meant that Arabs would have made up nearly 47 percent of its population.

Jerusalem presented a unique problem because it held profound religious significance for all three Abrahamic faiths.

UNSCOP recommended that Jerusalem and the nearby town of Bethlehem be placed under a special international regime, which was known as a corpus separatum, and which was administered directly by the United Nations Trusteeship Council.

Over 100,000 Jews lived in Jerusalem at the time, and the decision to exclude the city from the Jewish state was a source of serious frustration for the Jewish Agency.

The reasoning behind the corpus separatum was practical as much as symbolic. The decision to place Jerusalem under neither state’s sovereignty was intended to prevent conflict over holy sites, which included the Western Wall and the Church of the Holy Sepulchre, as well as the Haram al-Sharif (Temple Mount).

Under the plan, both states would have guaranteed free access to these sites for all religious communities.

On 23 September 1947, the General Assembly established an Ad Hoc Committee on the Palestinian Question to review UNSCOP’s findings.

The Arab Higher Committee was led by the Mufti Hajj Amin al-Husayni, and it rejected both the majority and minority proposals and argued that any plan that granted territorial sovereignty to a Jewish minority was inconsistent with the UN Charter and the right of self-determination.

The Jewish Agency was led by David Ben-Gurion and accepted the partition proposal.

The Agency had lobbied for additional territory in western Galilee and Jerusalem, but ultimately agreed to the plan as a basis for statehood.

Cold War dynamics also influenced the outcome, particularly because the United States was led at the time by President Truman who supported partition after intensive lobbying from Zionist organisations, while the Soviet Union under Joseph Stalin also voted in favour, partly to speed up British withdrawal from the Middle East.

The vote had originally been scheduled for 26 November but was delayed by three days, as supporters of partition feared they lacked the necessary two-thirds majority.

Intense lobbying continued during this delay, with pressure that was reportedly applied to smaller nations by Washington and Zionist groups.

On 29 November 1947, the General Assembly voted 33 in favour and 13 against, with 10 abstentions.

The plan had never received the consent of Palestine’s Arab population, who constituted roughly two-thirds of the territory’s inhabitants.

Fighting broke out almost immediately, and the British mandate ended on 14 May 1948, the same day on which David Ben-Gurion declared the establishment of the State of Israel.

The partition plan had been set out in Resolution 181 but was never implemented as written: war rather than diplomacy determined the final borders.
