Kazan Governorate
Kazan Governorate, together with seven other governorates, was established on , 1708, by Tsar Peter the Great's edict on the lands of the Khanates of Kazan, Sibir, and Astrakhan, with addition of some lands from the Nogai Horde. These were the areas historically governed by the Kazan Palace's Prikaz. As with the rest of the governorates, neither the borders nor internal subdivisions of Kazan Governorate were defined; instead, the territory was defined as a set of cities and the lands adjacent to those cities.
