This book examines the ways in which selfhood and cultural solidarity came to be understood and lived as historical identities during the 1800s. It examines the stages and conflicts in the process of ‘becoming historical’ through the works of prominent Prussian artists and intellectuals (Karl Friedrich Schinkel, Felix Mendelssohn, Jacob Grimm, Friedrich Karl von Savigny, Leopold von Ranke) who attached their personal visions to the reformist agenda of the Prussian regime that took power in 1840. The historical account of the evolution of analogous and inter-related commitments to a cultural reformation that would create communal solidarity through subjective identification with public memory is framed by the philosophical perspectives on historical selfhood provided by F. W. J. Schelling and his radical critics, Karl Marx and Søren Kierkegaard, thus drawing this story of building selves and communities in early nineteenth century Berlin into current debates about historical determined and contingently constructed identities.
