The term has been used extensively in 20th-century Thai historiography, partly as a way to disassociate the historical
Angkorian civilization—of which many archaeological sites are spread throughout present-day
Thailand—from the present-day Khmer people who form the majority population of
Cambodia, whom many Thais still believe to be an
inferior race unrelated to the people of the ancient empire. This discourse was popularized by 20th-century Thai nationalist thinker
Luang Wichitwathakan who incorrectly claimed that contemporary
Khmers are unrelated to the ethnic group responsible for the Angkorian civilization, coining the term "khom" for this purpose. By repurposing the term "khom" derived from the native Khmer term "
Khmer Krom" meaning "lowland Khmer", Wichitwathakan attempted to create a new ethnicity to accentuate a distinct separation between
Angkor and
Cambodia, despite the ethnic continuity between Angkor's builders and present-day Khmer being well-established. == Etymology ==
