The National Front is a white supremacist party. Rejecting the concept of racial equality, it argued that different races can be ranked on a hierarchy based on differing abilities. It believed that the "higher races" struggle against one another for world domination, and that racial segregation was natural and ordained by God. It promoted the conspiracy theory that non-whites were intentionally encouraged to migrate to Britain and other white-majority countries to breed with the indigenous inhabitants and thus bring about "white genocide" through assimilation. It opposed inter-racial marriage and miscegenation—typically referring to the latter as "mongrelisation"—and displayed particular anxiety about black men seducing white women.
