A referendum on becoming a US commonwealth was held in the Northern Mariana Islands on 17 June 1975.[1] The proposal was approved by 79% of voters.[1] As a result, the United States Congress approved the change of status on 24 March 1976.[1]
Four previous referendums on either integration with Guam or the islands' status had been held in 1958, 1961, 1963 and 1969. On each occasion a majority of Northern Mariana Islands voters had been in favor of integration with Guam, but Guamanian voters rejected integration in a 1969 referendum.
On 20 February 1975 the Northern Marianas' District Legislature put forward proposals to become a US commonwealth.[1] A threshold of 55% in favor was set in order for the referendum to pass.[1]
