プガチョフの乱
In 1782, under the impression of Pugachev's Rebellion, the Siberian kingdom was divided into three separate viceregencies (наместничество), centered at Tobolsk, Irkutsk and Kolyvan. These viceregencies were downgraded to the status of governorate in 1796 (Tobolsk Governorate, Irkutsk Governorate, Vyatka Governorate).
