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 (-5[1])about this period calls media flattery (15[1]-5[1])and school funding a (10[1])“public (10[1])and psychological wage” and (15[1])argues that prior (15[1])to this period four (*) million people (-5[1])participated in a general strike. Contra the Dunning School, W. E. (10[1])B. (10[1])DuBois's (10[2]-5[1])revisionist history of this period casts it as an attempted renewal of American democracy. (10[1])For 10 points, name this time period during (10[3]0[1])which America was revolutionized (10[1])by newly (10[1])freed slaves. (10[1])■END■
