British Mandate Palestine: History and End 1920-1948·5 min read

The 1922 Partition of the Palestine Mandate

In September 1922, the British government severed Transjordan from the Palestine Mandate, excluding about three fourths of the original territory from the promised Jewish National Home provisions.

The creation of Transjordan in 1922 represents the first major administrative partition of the British Mandate for Palestine, an event that reshaped the geopolitics of the modern Middle East. Under the terms of the post-World War I settlement, the entire territory on both sides of the Jordan River was initially slated for the establishment of a Jewish national home. However, geopolitical calculations and British colonial ambitions led to a dramatic restructuring of the mandate's geographical boundaries. This early partition officially severed nearly eighty percent of the original territory to form an autonomous Arab emirate under Hashemite leadership. Consequently, this administrative division set a historical precedent that restricted Jewish settlement exclusively to the lands west of the Jordan River.

Historical Background and the San Remo Framework

Following the collapse of the Ottoman Empire, the Allied Powers convened at the historic San Remo Conference in April 1920 to determine the future of the captured territories. It was during this international summit that Great Britain was officially assigned the Mandate for Palestine, with the explicit directive to implement the Balfour Declaration of 1917. The primary objective of the mandate was to facilitate the creation of a Jewish national home in historic Palestine, a territory that legally spanned both the eastern and western banks of the Jordan River. At this early stage, there was no international distinction or physical barrier separating the western half of the territory from the eastern portion. The entire geographic expanse was recognized under international law as a single cohesive unit dedicated to Jewish restoration.

The political landscape shifted rapidly when Emir Abdullah of the Hashemite family arrived in the region with an armed force, threatening to attack French forces in Syria. In response to this sudden regional instability, British Colonial Secretary Winston Churchill convened the Cairo Conference in March 1921 to pacify the Arab leader and stabilize British influence. Churchill offered Abdullah temporary administrative control over the territory east of the Jordan River, which was henceforth designated as Transjordan. This diplomatic compromise aimed to resolve local Arab grievances while securing British strategic interests across the region without committing massive military forces. However, this unilateral decision effectively sowed the seeds for the permanent separation of the eastern territory from the rest of the mandate.

Key Facts of the 1922 Partition

The formalization of the partition involved several critical legal steps and administrative shifts that permanently altered the boundaries of the Jewish national home. To execute this geographic division, the British government drafted specific provisions that allowed them to manage the eastern territories differently from the western portion. These maneuvers culminated in a formal appeal to the international community to sanction the separation. The League of Nations subsequently ratified these changes, creating a separate political entity that would eventually achieve full sovereignty.

  • Article 25 of the Mandate: The British government inserted Article 25 into the text of the Palestine Mandate, granting themselves the legal authority to postpone or withhold the application of the Jewish national home provisions in the eastern territories.
  • The August 1922 British Memorandum: Britain officially presented a memorandum to the League of Nations in August 1922, stating that the newly formed Emirate of Transjordan would be excluded from all obligations regarding Jewish settlement and immigration.
  • League of Nations Ratification: On September 16, 1922, the Council of the League of Nations approved the British request, which effectively severed about 77 percent of the original mandate's territory to create an exclusive Arab entity.

Political and Legal Analysis of the Separation

The partition of the mandate in 1922 remains a highly controversial decision that significantly reduced the land area available for Jewish national self-determination. By severing the vast lands of Transjordan, the British government immediately compromised the spirit of the Balfour Declaration, which had promised a Jewish national home across the entire historical region. This administrative move was widely perceived by Zionists as a betrayal of British commitments and a severe blow to the future development of the Jewish state. According to historical records detailing when Churchill severed Transjordan from Palestine, this decision was largely driven by a desire to appease Arab leadership at the expense of Zionist aspirations. This concession fundamentally altered the geographic scope of the Jewish national home before the mandate was even officially implemented.

Within the Zionist movement, the separation of Transjordan sparked deep internal divisions and gave rise to the Revisionist Zionist movement led by Ze'ev Jabotinsky. Jabotinsky and his followers fiercely opposed the partition, advocating for a Jewish state that would encompass both sides of the Jordan River as originally promised. Their slogan, "both sides of the Jordan," became a rallying cry against British appeasement policies and highlighted the profound sense of loss felt by many Jewish pioneers. Although mainstream Zionist leaders reluctantly accepted the partition to preserve their relationship with Britain, the decision fostered a lasting sense of distrust. This historical shift demonstrated that international treaties and promises could be unilaterally altered to serve the immediate colonial interests of the ruling power.

Conclusion and Modern Significance for Israel

The 1922 partition of the Palestine Mandate established the modern boundaries that continue to influence the geopolitical landscape of the Middle East. By carving out Transjordan, Great Britain created a separate Arab state, leaving only twenty-three percent of the original mandate for the Jewish national home west of the Jordan River. This historical reality refutes the common misconception that the Jewish state was established on the entirety of historic Palestine at the expense of Arab sovereignty. In truth, the first major partition of the region created a massive Arab state in Transjordan, which later became the Kingdom of Jordan, long before the United Nations proposed further divisions in 1947. This crucial context is essential for understanding the historical proportions of land distribution and compromise in the Arab-Israeli conflict.

For the modern State of Israel, the legacy of the 1922 partition underscores the immense sacrifices and territorial compromises that have characterized Jewish statehood from its inception. The creation of Jordan as an independent Arab state on historic mandate land highlights that Arab national aspirations were fulfilled in the vast majority of the original territory. Understanding this division is vital for defending Israel's historical legitimacy and countering narrative distortions that ignore this initial, massive territorial compromise. By recognizing that Transjordan was severed to create an Arab homeland, observers can better appreciate the narrow geographic margins within which Israel has had to build and defend its sovereign existence.
