Sumy Oblast

Sumy Oblast (Ukrainian: Сумська область, romanized: Sumska oblast), also known as Sumshchyna (Сумщина), is an oblast (province) in northeast Ukraine. The oblast was created in its modern-day form, from the merging of raions from Kharkiv Oblast, Chernihiv Oblast, and Poltava Oblast in 1939 by the Presidium of the Supreme Soviet of the Soviet Union. The estimated population is 1,035,772 (2022 estimate).

The administrative center of the oblast is the city of Sumy. Other important cities within the oblast include Konotop, Okhtyrka, Romny, and Shostka. The modern region combines territories of the historical Severia (northern part) and Sloboda Ukraine (southern part). On territory of the Sumy Oblast important centers of Ukrainian culture are located, such as the city of Hlukhiv which served as a hetman residence during the Cossack Hetmanate as well as the cities of Okhtyrka and Sumy which were regional centers of the Sloboda Ukraine.

The oblast has a heavy mix of agriculture and industry, with over 600 industrial locations. Among the most notable was the Soviet film stock manufacturer Svema in Shostka. Importantly, seven rivers pass through the oblast.
