Oblasts in the Russian Empire were considered to be administrative units and were included as parts of Governorates General or krais. The majority of then-existing oblasts were located on the periphery of the country (e.g. Kars Oblast or Transcaspian Oblast) or covered the areas where Cossacks lived.
