Jahrhunderts, Der (Myth of the Twentieth Century) – polemical treatise written by Nazi ideologue Alfred Rosenberg which espoused that all great culture in western civilization came from the minds of Germanic peoples but they had fallen in decline due to the negative influence of Jewish-based Christianity, Jesuits, Freemasons, and "conspirators of international Jewry". In his book, Rosenberg stressed that current and future struggles would not be ideological dogma, but blood against blood, and race against race for global dominance.
