SS Mayaguez was a U.S.-flagged container ship that attained notoriety for its 12 May 1975 seizure by Khmer Rouge forces of Cambodia, which resulted in a confrontation with the United States at the close of the Vietnam War.

Kampuchea, officially Democratic Kampuchea (DK) from 1976 onward, was the Cambodian state from 1975 to 1979, under the totalitarian dictatorship of Pol Pot and the Communist Party of Kampuchea (CPK), commonly known as the Khmer Rouge (KR). It was established following the Khmer Rouge's capture of the capital Phnom Penh, effectively ending the United States-backed Khmer Republic of Lon Nol. After Vietnam took Phnom Penh in 1979, it was disestablished in 1982 with the creation of the CGDK in its place.
