}}As a result of [[Ostsiedlung|German colonization]], the town became mostly German-speaking, putting indigenous Slavic speakers at disadvantage.<ref name=MUZ/> In 1516 local Germans enforced a ban on buying goods from Slavic speakers.<ref>Hieronim Kroczyński, ''Kołobrzeg zarys dziejów'', Wyd. Poznańskie, Poznań, 1979, p. 27 (in Polish)</ref> It was also forbidden to accept native Slavs to craft guilds, which indicates ethnic discrimination.<ref name=MUZ/>

In 1531 riots took place between supporters and opponents of the [[Protestant Reformation]].<ref name=MUZ/> In 1534 the city became mostly [[Lutheranism|Lutheran]] under the influence of [[Johannes Bugenhagen]]. In 1568, [[John Frederick, Duke of Pomerania]] and [[Bishopric of Cammin|bishop of Cammin]], started constructing a residence, finished by his successor [[Casimir VI, Duke of Pomerania|Casimir VI of Pomerania]] in 1582.<ref name=MUZ/> After the 1637 death of the last Pomeranian duke, [[Bogislaw XIV, Duke of Pomerania|Bogislaw XIV]], the city passed to his cousin, Bishop [[Ernst Bogislaw von Croÿ]] of Kammin. Occupied by [[Swedish Empire|Swedish]] troops during the [[Thirty Years' War]] in 1637, some of the city's inhabitants sought refuge in nearby Poland.<ref name=MUZ/> The city was granted to [[Brandenburg-Prussia]] after the [[Treaty of Westphalia]] (1648) and the [[Treaty of Stettin (1653)]], and with all of [[Farther Pomerania]] became part of the [[Province of Pomerania (1653-1815)|Brandenburgian Pomerania]].

Now renamed Cöslin as part of the [[Kingdom of Prussia]], the city was heavily damaged by a fire in 1718, but was rebuilt in the following years. In 1764 on the Chełmska Hill, now located within the city limits, a Pole Jan Gelczewski founded a paper mill that supplied numerous city offices.<ref name=MUZ/>
