Irregular Regions
subject: administrative geography
description: Imperial officials who daydreamed about looking out the frosty windows of the Winter Palace onto a relentlessly well-organized and highly standarized state were in for disappointment. Wedged in at the margins of the more-or-less regularized provinces of the empire were a handful of regions with what might be described as temporary, underdeveloped, or relatively autonomous administrative structures. These included the territory of the Don Cossack Host, the former kingdom of Georgia, the territory of the Caucasian mountaineers, the lands claimed by the Russian American Company on the North American continent (with the Aleutian Islands), Chukotka, the okrugs of Kamchatka and Okhotsk, and two chunks of land in remote northern Finland.

(Semi-)Autonomous Regions
subject: administrative geography
description: The Piadyshev Atlas describes two semi-autonomous, or primary, administrative regions (the atlas does not include mention of namestnichestva or governor-generalships): the Grand Duchy of Finland (acquired in 1809); the Kingdom of Poland (reconstituted from the lands acquired by Russia via the partitioning of the Polish-Lithuanian Commonwealth under Catherine II).

Provinces (Gubernii)
subject: administrative geography
description: Provinces were the building blocks of the imperial administrative structure. Starting in the 18th century, provinces came in two forms: the guberniia and the oblast'. Empress Catherine II determined the shape and structure of the former, dominant form, with her 1775 Statute on Guberniia Administration (law number 14392). At that time there were 40 gubernii; by the 1820s there were 49, the geography of which corresponds - some argue - to the geography of the core of the Russian Empire. Included here are the 7 gubernii of the Grand Duchy of Finland as well, bringing the total number of gubernii shown on the atlas to 56. The guberniia was a secondary administrative unit.

Districts
subject: administrative geography
description: The districts were tertiary administrative units. Each was nested within a secondary unit (guberniia, oblast', or irregular division). The Piadyshev Atlas describes 583 districts, including 24 vladeniia and okruga in Georgia, 7 nachal'stva in the Don Cossack lands, 6 tsinuty in Bessarabia, and 5 ober-hauptmannshafften in Kurliand.

Provincial towns
subject: urban space, administrative space
description: The provincial town (губернский город) was the administrative capital of the province, the seat of the civil governor, and in some cases a military governor or governor-general. Provincial towns ranged from the relatively humble (Vologda) to the grandiose (St. Petersburg). Some boasted long urban histories, such as Moscow or Kiev, while others were essentially conjured out of thin air by imperial decree, such as Kherson and Simferopol. A few qualified as economic centers or trading hubs (think Riga or Novgorod); a handful were cultural centers (think Vilno or Tiflis). Others were frontier towns first and foremost, such as Ufa and Tobol'sk.

District towns
subject: urban space
subject: administrative space
description: The Piadyshev Atlas contains attestations of 459 district (uezd) towns. This is a bit odd, given the fact that the atlas describes 591 districts. How might we make up - or at least explain the shortfall? To start, the 43 districts in the Grand Duchy of Finland, the 8 voevodstvos in the Kingdom of Poland, the 24 domains (владения) and districts (округа) of the (former) Kingdom of Georgia, and the 7 nachal'stva of the Don Cossack territory lacked district seats per se, as these regions had different administrative structures than the rest of the empire. That brings the target number down to 509, from 592. GIS software makes it incredibly easy to count the number of districts with at least one location designated as a district town: 444. In other words, the dataset is missing 66 district towns? Happily, that is not the case. You see, in most cases, a district that was home to a provincial seat (gubernskij gorod) did not have a separate district town. That means that we can add our provincial towns to the count. 55 districts were home to provincial towns (excluding Okhotsk and Kamchatka, which were not organized as regular provinces), but in 5 cases the atlas shows the presence of both a provincial and a district town. Eliminating those redundancies, and treating provincial towns as district towns, we can now cover 494 districts. What about the remaining 15? Careful scrutiny reveals that according to the atlas, precisely 15 districts lacked district towns altogether (3 in Iakutsk, 1 in Tavrida, 1 in Kavkazskaia oblast', 3 in Kharkov, 4 in Minsk, 3 in Vilensk). The math is a dizzying and the explanations myriad, but the result is that the dataset in fact contains what it ought to, given the parameters of the source from which it is drawn.

Provinces (Oblasti)
subject: administrative space
description: Provinces came in two forms. While the guberniia was the more standardized and more prolific form, the oblast' played an important role in the administrative geography of the empire as well. The oblast' was a secondary administrative unit. A quick glance at the map reveals that one of the hallmarks of the oblast' was location. If gubernii constituted the "core", the oblast' helped define the periphery of state administration. From west to east, the 5 oblasts are: Belostok, Bessarabia, Kavkaz (Caucasus), Irkustk, Iakutsk.
