The term "Siberian Expansion" refers to the historical process of Russian territorial growth into the vast region of Siberia. This expansion began in the late 16th century and continued into the 19th century, driven by the search for resources, land, and trade routes. The Russian Empire established settlements and forts, gradually extending its influence over the area. During this period, the Cossacks played a significant role in exploring and conquering Siberian territories. The expansion led to the incorporation of diverse indigenous peoples and cultures, as well as the exploitation of natural resources like fur, minerals, and timber, shaping the economic landscape of Russia.
