Pinsk is first mentioned in the chronicles of 1097 as Pinesk, a town belonging to Sviatopolk of Turau. The name is derived from the river Pina. Pinsk's early history is closely linked with the history of Turau. Until the mid-12th century Pinsk was the seat of Sviatopolk's descendants, but a cadet line of the same family established their own seat at Pinsk after the Mongol invasion of Rus in 1239.
The Pinsk principality had an important strategic location, between the principalities of Navahrudak and Halych-Volynia, which fought each other for other Ruthenian territories.

During the Cossack rebellion of Bohdan Khmelnytsky (1640), it was captured by Cossacks who carried out a pogrom against the city's Jewish population; the Poles retook it by assault, killing 24,000 persons and burning 5,000 houses. Eight years later the town was burned by the Russians.
In 1648, on the eve of the Russo-Polish War (1654-1667), Pinsk was occupied by Ukrainian Cossack army under commander Niababy and could only be reconquered with great difficulty by prince Janusz Radziwi??, a high-ranking commander in
