Machine translation, like DeepLorGoogle Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
You must provide copyright attribution in the edit summary accompanying your translation by providing an interlanguage link to the source of your translation.

Obolensk is also the name of a modern settlement (established 1975 as a base for the Soviet Biopreparat biological weapons program, and named for the historical city) in Serpukhovsky District, Moscow Oblast.
It was established in c. 1270 by Yury, the fifth son of Mikhail of Chernigov. Ruled by the sovereign House of Obolensk in the 14th and 15th centuries, the principality was incorporated into the Grand Duchy of Moscow in 1494. The Obolensky family remained in power as governors. In the 1678 census of the Tsardom of Russia, the Obolensk district incorporated 146 villages with a total of 6,501 inhabitants.
