Originally a fishing settlement called Bydgozcya ("Bydgostia" in Latin, Bromberg in German), the city became a stronghold for the Vistula trade routes. In the 13th century it was the site of a castellany, first mentioned in 1238. The city was occupied by the Teutonic Knights in 1331, and incorporated into the monastic state of the Teutonic Knights. The city was relinquished by the Knights in 1343 with their signing of the Treaty of Kaliscz along with Dobryznia and the remainder of Kuyavia.

King Casimir III of Poland, granted Bydgoszcz city rights (charter) on April 19, 1346. The city increasingly saw an influx of Jews after that date. In the 15th-16th centuries Bydgoszcz was a significant site for wheat trading. The Treaty of Bydgoszcz signed between King John Casimar II of Poland and Elector Frederich William II of Brandenburg-Prussia in the city in 1657, announcing a military alliance between Poland and Prussia against Sweden.

Bydgoszcz followed the history of Greater Poland until 1772, when it was annexed by the Kingdom of Prussia in the First Partition of Poland and incorporated into the Netze District as Bromberg and, later, West Prussia. During this time, a canal was built from Bromberg to Nakło which connected the north-flowing Vistula River via the Brda to the west-flowing Noteć, which in turn flowed to the Oder via the Warta.
In 1807, after the defeat of Prussia by Napoleon, and the signing of the Treaty of Tilsit, Bromberg became part of the Duchy of Warsaw. In 1815 it returned to Prussian rule as part of the autonomous Grand Duchy of Poznań (the Province of Posen after 1848) and the capital of the Bromberg region. After 1871 the city was part of the German Empire. After World War I and the Great Poland Uprising, Bromberg was assigned to Poland in 1919. In 1938 it was made part of the Pomeranian Voivodeship.
