Prehistory

Modern researchers trace the history of Sedniv to the Danish settlement of da:Seden, from which the city got its name.^[3] When the territories of the modern-day Chernihiv region were captured by the Rurik dynasty, Sedniv was renamed to Snovesk (Ukrainian: Сновеськ).

The settlement is first mentioned in chronicles as an ancient fortress city of Snovsk. In 1068, Prince Sviatoslav with three thousand soldiers defeated 12 000 soldier Cuman army near Snovsk. The name comes from the River Snov ("sleep" - wash, bathe). Folk legend tells other versions of the town's name:

"The devastating hordes of the Crimean Tatars attacked Snovsk, but could not take the city-fortress. The Tatars then called the city of Snovsk "Sidnaame"(сидняме), which translated from Tatar language as if to mean evil and brave. Hence - Sedniv."

From 10th to 11th centuries, Snovsk was one of the strongholds of Kievan Rus', the center of a separate administrative unit - Snovskian Thousand.

From 12th to 13th centuries, Snovsk was a part of the Chernihiv principality that was later destroyed by Tatars invaders in 1239.

In the mid-14th century, the city was incorporated into the Grand Duchy of Lithuania.

Soviet administration was established in August 1920 with the formation of Sedniv Village Council. During the post-war administrative reform, the town became part of Chernihiv Oblast's Horodnia Raion.

Sedniv was heavily hit by the Holodomor. As the town's inhabitants heavily resisted Soviet collectivization policies, the town was included into the Soviet black boards.^[6] At least 145 people perished during this period, and the town itself was downgraded into a village.

Russian forces entered Sedniv in early morning hours of February 24, 2022.^[7] The town was initially used as staging area for further Russian advances in Chernihiv Oblast; according to locals, Russian forces came in three waves.

Local inhabitants reported excessive looting and intimidation by Russian forces;^[7] according to local culturologists, a number of places of historical and architectural significance were either damaged or outright destroyed.^[8][9] Days before Russian army officially pulled back from North Ukraine, local media reported that on-the-ground military units were burning corpses of their fallen in a local starch factory furnaces.^[10]
