The city of Chernihiv was the second most important Ukrainian city during the Rus' period of Ukrainian history, often serving as a major regional capital. Danylo of Chernihiv wrote of his pilgrimage to Jerusalem during this era. The numerous architectural monuments of the city bear witness to the invasions suffered, including those by the Tatars/Mongols, Lithuanians, Poles, Russians, and Nazis. On the territory of the region took place numerous tragic events such as Battle of Kruty, Tragedy of Kryukivka, and many others.

Chernihiv region was famous for its specific style of folk icon-painting. Brightness and realistic depictions of the saints were typical for it, with red and hot yellow paints used. The icons were decorated by flowers which reminded of Slavonic pre-Christian traditions. The icons from Chernihiv region were spread outside its territory. Many of them are preserved in the Museum of Ukrainian home icons of the Radomysl Castle.
Most of Ukraine's oblasts are named after their capital cities, officially referred to as "oblast centers" (Ukrainian: , translit. oblasnyi tsentr). The name of each oblast is a relative adjective, formed by adding a feminine suffix to the name of respective centre city: Chernihiv is the centre of the Chernihivs'ka oblast' (Chernihiv Oblast). Most oblasts are also sometimes referred to in a feminine noun form, following the convention of traditional regional place names, ending with the suffix "-shchyna", as is the case with the Chernihiv Oblast, Chernihivshchyna.
