History of Słupca dates back to the Middle Ages. On November 15, 1290 Polish Duke Przemysł II granted Słupca town rights. In 1296 Słupca's town privileges were renewed; this time Słupca was granted a range of new privileges. It is inhabited by about 1000 people. On November 11, 1314 King Władysław I the Elbow-high granted Slupca a privilege to establish a mint and produce coins. Since 1314 it was located in the Kalisz Voivodeship of the Polish Kingdom. In 1331 the town was raided and burned down by the Teutonic Knights. A defensive wall of the length of 1100 meters was constructed between 1375 and 1382. During the Thirteen Years' War (1454–1466) the town of Slupca sent 20 knights so as other 9 biggest towns of Greater Poland did. By the end of 15th century Słupca was inhabited by about 2000 people. During the Swedish occupation of Poland the town was looted several times and after the Second Partition of Poland in 1793 it was annexed by Prussia. In 1794 it was a base for the Polish Kościuszko Uprising.
