<P> According to Michel Foucault, in the 19th century the essentialist notion of the "race" was incorporated by racists, biologists, and eugenicists, who gave it the modern sense of "biological race" which was then integrated to "state racism". On the other hand, Foucault claims that when Marxists developed their concept of "class struggle", they were partly inspired by the older, non-biological notions of the "race" and the "race struggle". In a letter to Friedrich Engels in 1882 Karl Marx wrote: You know very well where we found our idea of class struggle; we found it in the work of the French historians who talked about the race struggle . For Foucault, the theme of social war provides the overriding principle that connects class and race struggle . </P> <P> Moses Hess, an important theoretician and labor zionist of the early socialist movement, in his "Epilogue" to "Rome and Jerusalem" argued that "the race struggle is primary, the class struggle secondary...With the cessation of race antagonism, the class struggle will also come to a standstill . The equalization of all classes of society will necessarily follow the emancipation of all the races, for it will ultimately become a scientific question of social economics ." </P> <P> In modern times, emerging schools of thought in the U.S. and other countries hold the opposite to be true . They argue that the race struggle is less important, because the primary struggle is that of class since labor of all races face the same problems and injustices . </P> <P> Riots with a basically nationalist background are not included . </P>
