Southern Ukraine (Ukrainian: Південна Україна, Pivdenna Ukrayina) refers, generally, to the territories in the South of Ukraine. The territory usually corresponds with the Soviet economical district, the Southern Economical District of Ukrainian SSR. The region is completely integrated with a marine and shipbuilding industry. The region primarily corresponds to the former Russian Kherson, Taurida and most of the Yekaterinoslav Governorates that appeared after disintegration of the Novorossiysk Governorate which expanded across the northern coast of Black Sea after the Russian-Ottoman Wars of 1768–74 and 1787–92. Prior to that the area belonged to the Crimean Khanate realm and its satellites protected militarily by the Ottoman Porte.
