Middle Ages

The lower Rega area around Gryfice and Trzebiatów was the site of a West Slavic Lechitic gród (fortified settlement) in the 9th century. The territory became part of the emerging Polish state under Mieszko I around 967.^[2] It was part of the Duchy of Pomerania, which separated itself from Poland as a result of the fragmentation of Poland. The first recorded mention of the town comes from 1170 when the Pomeranian Duke Casimir I granted a few villages and oversight of a church in the town to settlers from Lund in Sweden. In the early 13th century Trzebiatów became the seat of Duchess Anastasia of Greater Poland, who rebuilt the old castle into her residence.^[3] In 1224, Anastasia brought Premonstratensian nuns to the town.^[3] In the first half of the 13th century, German settlers invited by the Pomeranian Duke Barnim I began to settle in the area. In 1277, this settlement received town privileges under the Lübeck Law. In 1416, the town became part of the Hanseatic League,^[1] then served as an important trade post and developed architecturally, with a typical Brick Gothic-style influence. It had trading connections with major cities such as Gdańsk and Copenhagen.^[1]

Modern era

In 1504, Johannes Bugenhagen moved to the town and became Rector of the local school.^[4] On 13 December 1534 a diet was assembled in the town, where the Dukes Barnim XI and Philip I as well as the nobility officially introduced Lutheranism to Pomerania, against the vote of Erasmus von Manteuffel-Arnhausen, Prince-Bishop of Cammin. In the following month Bugenhagen drafted the new church order (Kirchenordnung), founding the Pomeranian Lutheran church (today's Pomeranian Evangelical Church).^[5][6][7]

As a dowager, Sophia of Schleswig-Holstein-Sonderburg (1579–1658), widow of Philip II, Duke of Pomerania, lived in Treptow. Sophia's dower was a former nunnery, which she converted into a palace. While in Swedish service and thereafter Duke Francis Henry of Saxe-Lauenburg spent a lot of time with Duchess dowager Sophia in Treptow. Sophia's and Francis Henry's fathers were cousins. On 13 December 1637 Francis Henry and Marie Juliane of Nassau-Siegen (1612–1665) married in Treptow.^[8] Their first child was born in Treptow in 1640.^[9] Francis Henry also served Sophia as administrator of the estates pertaining to her dower.^[9]

During the Thirty Years' War, in 1630, the town was besieged by forces of the Holy Roman Empire.^[10] In 1637 Bogusław XIII died leaving the Pomeranian ducal house extinct. At this point the duchy came under Swedish occupation with the Brandenburgian electors claiming succession in Pomerania. After the Thirty Years War the town became part of Brandenburg-Prussia in the Peace of Westphalia of 1648. It was part of the province of Pomerania. During the Seven Years' War, the town was occupied by Russia.^[10]

In 1750 the local palace was refurbished in classicist style for General Frederick Eugene of Württemberg, who resided there – with interruptions – until 1763. In the late 18th century the Polish noblewoman and writer Maria Wirtemberska née Czartoryska resided at the palace,^[3] and her early works and translations were created here. The painter Jan Rustem visited her several times, and his paintings were part of the palace's art collection.^{[citation needed]} The palace now houses a State public library, founded in 1946 and named after Maria Wirtemberska née Czartoryska since 1999.

In 1806 the town was captured and then occupied by France.^[10] From 1871 to 1945 it former part of the German Reich.

20th century

During World War II, in February 1945, the German-perpetrated death march of Allied prisoners-of-war from the Stalag XX-B POW camp passed through the town.^[11] Near the end of the war, in February 1945, despite the approaching front, the authorities did not permit the evacuation of the town's population. It was not until March 4 that the order to evacuate was issued, the day after remnants of the army had retreated from the town, leaving the civilian population to fend for itself. Allied Polish and Russian forces then entered the town, and afterwards it became again part of Poland, although with a Soviet-installed communist regime, which stayed in power until the Fall of Communism in the 1980s. The town's German population was expelled, and the town was resettled with Poles, in accordance with Potsdam Agreement.^[12]

Since 1 January 1999, the town has been within West Pomerania Voivodeship, upon its formation from the former Szczecin and Koszalin Voivodeships.
