Siberian Frontiers explores Russia's expansion into Siberia, a pivotal period in world history. This territorial acquisition, driven by the lucrative fur trade and the ambition for resources, had profound consequences for indigenous populations and reshaped global commerce. The book highlights how this contiguous land grab differed from overseas colonialism, significantly influencing Russia's identity and its relationship with Asia. The Russian state implemented administrative and legal frameworks, affecting land ownership, taxation, and religious conversion, further altering the region's socio-political landscape. The book presents a comprehensive account of Russia's eastward march from the late 16th through the 19th centuries.

Initially, the book sets the stage by examining the diverse indigenous cultures, economies, and political systems of pre-colonial Siberia. It then analyzes the early stages of Russian penetration, focusing on the role of Cossack explorers, fur traders, and state officials in establishing control over key territories. The book connects history with anthropology, economics, and environmental studies, emphasizing the agency of indigenous actors who resisted and adapted to Russian expansion.
