This third and final entry in Andrei Grinëv’s Russian Colonization of Alaska series takes the history of the Russian colonies in North America From Heyday to Sale, 1818–1867. The text, if billed as a monograph, is foremost a synthesis—a collation not only of other scholars’ findings, but of Grinëv’s own considerable scholarship as well. Anyone acquainted with the series thus far will find no surprises as regards Grinëv’s central thesis. As in previous volumes, the author reserves his most critical attention for arguing Russia’s imperial project in North America as an example of “colonial politarism,” with “politarism” here being Karl Marx’s “Asiatic mode of production” (p. 2). Its significance notwithstanding, the argument makes infrequent an appearance in what is otherwise an exceptionally thorough history of Russian America’s final decades. Beginning with the departure of the merchant Aleksandr Baranov as the colonies’ executive in 1818, Grinëv organizes his survey with similar keystones in Russian America’s political history, namely, the five-year terms of Baranov’s successors, nearly all of which serve as headings in one of five chapters. The first of these addresses the challenges of replacing the long-serving Baranov, and the importance of his successors being chosen exclusively from among the Navy’s officer-gentry. The second, bound 1825 to 1840, examines the relation between imperial foreign policy and the ruling Russian-American Company’s efforts to consolidate ties with the Alaska Natives on whose labor, land and waters the Company depended for profit. Readers familiar with the literature will recognize both topics as staples of the historiography, but Grinëv’s intention here is to probe and tweak, not overhaul.
