Since 1150, it was known as Mychesk. The settlement probably was destroyed during the Mongol invasion in 1240, after which the region fell under Mongol suzerainty. In the 14th century it became part of Lithuania and subsequently the Polish–Lithuanian union after the Union of Krewo (1385). The town was raided by Tatars in 1399, 1416 and 1462. As part of the Kingdom of Poland from 1569 it was known under the name of Radomyśl. Administratively it was part of the Kyiv Voivodeship in the Lesser Poland Province of the Polish Crown. In the beginning of the 17th century the Radomysl paper mill was founded, the first paper mill of present-day central Ukraine. After the Second Partition of Poland in 1793 the town was annexed by the Russian Empire and renamed to its current name. It was included in the Kyiv Governorate.
