What most people don't know is that Marx was an out and out racist and anti-Semite. He didn't think much of Mexicans. Concerning the annexation of California after the Mexican-American War, Marx wrote: "Without violence nothing is ever accomplished in history." Then he asks, "Is it a misfortune that magnificent California was seized from the lazy Mexicans who did not know what to do with it?" Friedrich Engels, Marx's co-author of the "Manifesto of the Communist Party," added, "In America we have witnessed the conquest of Mexico and have rejoiced at it. It is to the interest of its own development that Mexico will be placed under the tutelage of the United States." Much of Marx's ideas can be found in a book written by former communist Nathaniel Weyl, titled "Karl Marx, Racist" (1979).
In a July 1862 letter to Engels, in reference to his socialist political competitor, Ferdinand Lassalle, Marx wrote, ". . . it is now completely clear to me that he, as is proved by his cranial formation and his hair, descends from the Negroes from Egypt, assuming that his mother or grandmother had not interbred with a nigger. Now this union of Judaism and Germanism with a basic Negro substance must produce a peculiar product. The obtrusiveness of the fellow is also nigger-like."
Engels shared much of Marx's racial philosophy. In 1887, Paul Lafargue, who was Marx's son-in-law, was a candidate for a council seat in a Paris district that contained a zoo. Engels claimed that Paul had "one eighth or one twelfth nigger blood." In an April 1887 letter to Paul's wife, Engels wrote, "Being in his quality as a nigger, a degree nearer to the rest of the animal kingdom than the rest of us, he is undoubtedly the most appropriate representative of that district."
