Under Russian administration, the territory of Belarus was divided into the "guberniyas" of Minsk, Vitebsk, Mogilyov, and Hrodno. Belarusians were active in the guerrilla movement against Napoleon's occupation.. With Napoleon's defeat, Belarus again became a part of Imperial Russia and its "guberniyas" constituted part of the Northwestern Krai. The anti-Russian uprisings of the gentry in 1830 and 1863 were subdued by government forces.
