Słupsk is a city in northern Poland. It is located on the Słupia River in the Pomeranian Voivodeship. This area is part of a larger historical region called Pomerania. Słupsk is home to about 88,835 people, making it one of Poland's most populated cities for its size. It is also the main administrative center for Słupsk County.
Słupsk started as a small settlement in the early Middle Ages. It was granted city rights in 1265. By the 1300s, it became an important center for trade and local government. It was even connected to the Hanseatic League, a powerful group of trading cities. For many years, from 1368 to 1478, it was home to the Dukes of Słupsk. After World War II, Słupsk became part of Poland again.

History of Słupsk
Early Beginnings
Słupsk grew from several small settlements along the Słupia River. This river had a special crossing point that connected important trade routes. Because of this, a grod (a fortified Slavic settlement) was built on an island in the river. This fortress was well protected by swamps and the river itself.
Archaeological digs show that the grod was on an artificial hill. It had a natural moat from the river and was protected by a palisade (a fence of strong wooden stakes). Records suggest that Słupsk was part of Poland as early as the 10th century.
Becoming a City
Some historians believe Słupsk was first mentioned in 1015, when the Polish king Boleslaus I the Brave took control of the town. In the 12th century, it became one of the most important areas in Pomerania.
The city likely received its city rights in 1265. These rights were later confirmed and expanded in 1310 and 1313. In 1337, the leaders of Słupsk bought the village of Stolpmünde (now Ustka). They then built a port there, which helped the city's economy grow through sea trade.
From 1368, Słupsk became the center of its own small state, the Duchy of Słupsk. Its dukes were connected to the Kings of Poland. Słupsk remained under Polish influence until 1474.
Later Years and Changes
In the 1500s, the Protestant Reformation came to Słupsk. Many people in the town started to follow Lutheranism. In 1637, the ruling family of Pomerania ended. After some wars, Słupsk came under the control of Brandenburg-Prussia in 1653.
After the Thirty Years' War, Słupsk lost some of its importance. However, its economy grew steadily. In the 19th century, it became the second-largest city in the province in terms of people and industry.
In 1807, during the Napoleonic Wars, Polish soldiers briefly took control of the city. In 1815, Słupsk became part of the Province of Pomerania (1815–1945). A railway line reached Słupsk in 1869, connecting it to Gdańsk.
The city grew a lot in the 19th century. A new city hall was finished in 1901, and a tram line opened in 1910. Before World War I, Słupsk had about 34,340 people.
World War II and After

During World War II, the city's growth stopped. After the war, Słupsk became part of Poland again. Most of the German people living there either left or were moved out. Poles, many of whom had been moved from eastern Polish territories, settled in the city.
Life in Słupsk began anew. In 1945, schools and workshops opened. Trams and trains started running again. The city became a cultural hub. In the 1950s, new theaters and a college were started. Słupsk even had one of the first cinerama cinemas in Poland. The first Polish pizzeria opened in Słupsk in 1975.
Modern Słupsk
After 1989, many street names in Słupsk were changed. Many old buildings were also renovated. In 1999, Słupsk Voivodeship (a type of province) was dissolved. Słupsk became part of the larger Pomeranian Voivodeship.
In 2014, Słupsk elected Robert Biedroń as its mayor. He was the first openly gay mayor in Poland.
