Ukrainian Oblast
Ukraine is subdivided into 27 regions: 24 oblasts, one autonomous republic, and two "cities with special status".
The administrative division in Ukraine was directly inherited from the local republican administration of the Soviet Union, the Ukrainian Soviet Socialist Republic, and has not changed majorly since the middle of 20th century. It is somewhat complex as beside having couple of levels of a territorial subdivision, it also has its own classification for various settlements.
