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 (15[1])argues that prior (15[1])to this period four (*) million people participated in a general strike. Contra the Dunning School, W. E. B. (10[1])DuBois's (10[3]-5[1])revisionist (10[1])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. (10[1])■END■
