Similarities with the Nazi propaganda term "Cultural Bolshevism" have been noted, the contemporary conspiracy theory originated in the US during the 1990. Originally found only on the far-right-republican-nazi political fringe, the term began to enter mainstream discourse in the 2010s and is now found globally. The conspiracy theory of a Marxist culture war is promoted by right-wing politicians, fundamentalist religious leaders, political commentators in mainstream print and television media, and white supremacist terrorists, and has been described as "a foundational element of the alt-right worldview". Scholarly analysis of the conspiracy theory has concluded that it has no basis in fact.
