1963 Northern Mariana Islands integration referendum

An unofficial referendum on integration with Guam was held in the Northern Mariana Islands on 27 October 1963.[1] Although the proposal was approved by voters,[1] the islands were not integrated.


Previous referendums in 1958 and 1961 had been in favor of integration. Both the Guam Legislature and Saipan Congress had passed resolutions requesting reunification.[2] The 1963 referendum was organized by the local Parliament as members wanted the islands to integrate with Guam, and was timed to coincide with the 1964 visit of a United Nations commission looking at the status of the UN Trust Territories.[1][2]

The results were presented to the mission, with the mission's report responding that secession from a UN Trust Territory was not possible "and should be regarded as firmly settled".[2]
