MERCI CAMARADE BRONSTEIN
This is Leon Trotsky's 1930 work, "The History of the Russian Revolution", from which shown above is a passage. The last word in that passage is "расистов", whose Latin transliteration is "racistov", i.e., "racists". This work here is the first time in history one will ever find that word.
My more doubtful readers may check the internet, the microfiche and microfilm at the local library, as well as the numerous books arrayed along the shelves there, but they shall never find an earlier usage of the word "racist" than Trotsky's coinage of the word here.
