|Сѣверія (Old Church Slavonic)|
Severia or Siveria (Old East Slavic: Сѣверія, Ukrainian: Сіверія or Сіверщина, translit. Siveria or Sivershchyna, Russian: Северщина, Severshchina; Polish: Siewierszczyzna) is a historical region in present-day northern Ukraine, eastern Belarus and southwestern Russia, centered on the city of Novhorod-Siverskyi in Ukraine.
The region received its name after the Severians, an East Slavic tribe which inhabited the territory in the late 1st millennium A.D. Their main settlements included the present-day cities of Novhorod-Siverskyi, Chernihiv (Chernigov), Putyvl (Putivl), Hlukhiv (Glukhov), Liubech, Kursk, Rylsk, Starodub, Trubchevsk, Sevsk, Bryansk, and Belgorod.
According to the Primary Chronicle, the Severians paid tribute to the Khazars, along with the neighboring Polans. Prince Oleg of Novgorod (reigned 879–912) conquered them and incorporated their lands into the new principality of Kievan Rus'. By the time of Yaroslav the Wise (1019–1054) the Severian peoples had lost most of their distinctness, and the areas of Severia along the upper course of the Desna River came under the control of Chernihiv.
In 1096, Oleg I of Chernigov (also referred to as Oleh) created a large Severian Principality, which stretched as far as the upper reaches of the Oka River. Until the end of the century, the principality served as a buffer state against Cuman attacks. Its most celebrated ruler was Prince Igor (1150–1202), whose exploits are recounted in the 12th century epic The Tale of Igor's Campaign.
After the Mongol invasion of Rus’, the principality fell into ruin, however it remained intact throughout repeated Tatar invasions. Unfortunately, not much is known about this period as Severia was rarely mentioned in written accounts of the 13th and 14th centuries. By the 15th century, it was taken over by the Grand Duchy of Lithuania, whose Gediminid princes (Ruthenian-speaking and Orthodox by religion) established their seats in the cities of Novhorod-Siverskyi, Starodub, and Trubchevsk. After the Lithuanian defeat at the Battle of Vedrosha, the Severian Principality passed to Moscow. It remained as part of Imperial Russia for centuries, except for the short period between 1618 and 1648, when it was incorporated into the Polish-Lithuanian Commonwealth following the Truce of Deulino (1618).
In the 18th century, the hetmans of Ukraine established residences in the towns of Baturin (ukr.Baturyn), Glukhov (ukr.Hlukhiv), and Pochep. Glukhov, in particular, developed into a veritable capital of 18th-century Ukraine.
Following the Bolshevik Revolution, the Severian lands, full of Southern Russian (Ukrainian) architecture, and populated by a mixture of Ukrainians and Russians, were divided between the Ukrainian and Russian Soviet republics, finally breaking up the land of the former Severians.
Since 16-17 cc., the specific Severian icon-painting style had been forming. It was much impressed by conservative Byzantine specimens which dominated in the Grand Duchy of Moscow. Severian icons are charaсterized by internal restraint, severeness and asceticism. These features survived during the Baroque epoch: volume and emotions were almost absent. The collection of Severian icons is preserved in the Museum of Ukrainian home icons of the Radomysl Castle.
