The United Nations Partition Plan for Palestine was a proposal by the United Nations, which recommended a partition of Mandatory Palestine at the end of the British Mandate. On 29 November 1947, the UN General Assembly adopted the Plan as Resolution 181(II). 

The resolution recommended the creation of independent Arab and Jewish States and a Special International Regime for the city of Jerusalem. The Partition Plan, a four-part document attached to the resolution, provided for the termination of the Mandate, the progressive withdrawal of British armed forces and the delineation of boundaries between the two States and Jerusalem.

Part I of the Plan stipulated that the Mandate would be terminated as soon as possible and the United Kingdom would withdraw no later than 1 August 1948. The new states would come into existence two months after the withdrawal, but no later than 1 October 1948. The Plan sought to address the conflicting objectives and claims of two competing movements, Palestinian nationalism and Jewish nationalism, or Zionism. The Plan also called for Economic Union between the proposed states, and for the protection of religious and minority rights.

The Plan was accepted by the Jewish Agency for Palestine, despite its perceived limitations.  Arab leaders and governments rejected it   and indicated an unwillingness to accept any form of territorial division, arguing that it violated the principles of national self-determination in the UN Charter which granted people the right to decide their own destiny. 

​​​​​​​Immediately after adoption of the Resolution by the General Assembly, a civil war broke out and the plan was not implemented.
