Changes

The Siamese, the residents of the modern Thailand (called “Siam” until 1939), destroyed the Khmer empire with conquests up until the 14th century.  But “Khmer Republic” came back as the official name for Cambodia in 1970-75, and the “Khmer Rouge” was a Cambodian communist movement that savagely killed about 2 million Cambodians in the 1970s and destroyed much of the nation after the United States left nearby Vietnam.  Later Vietnam communists invaded and overthrew the Cambodian communists.
