The end of this historical period is described as “property and privilege, shrieking to its kind..recognized the voice of its own” in a book titled for this period which uses the phrase “dictatorship of labor” to unite two different proletariats. A book titled for this period states that the “Machine and harnessed Power” veil the “Surplus Value” that the “dark proletariat” produces. That book about this period calls media flattery and school funding a “public and psychological wage” and argues that prior to this period four (*) million people participated in a general strike. Contra the Dunning School, W. E. B. DuBois's revisionist history of this period (10[1])casts it as an attempted renewal of American democracy. For 10 points, name this time period during which America was revolutionized by newly freed slaves. ■END■ (10[1])
