Book excerpt: This thoughtful book describes the range of nationalist ideas that have taken root in Russia since 1856. Drawing on a wide range of archival documents and unparalleled interview material from the post-Soviet period, Tuminez analyzes two cases_Russian panslavism in 1856-1878 and great power nationalism in 1905-1914_when aggressive nationalist ideas clearly influenced Russian foreign policy and contributed to decisions to go to war. Yet not all forms of nationalism have been malevolent, and the author assesses competing nationalist ideologies in the post-Soviet period to clarify the conditions under which a particularly belligerent nationalism could flourish and influence Russian international behavior.
