City (pop., 2000 est.: 384,500), northern Poland. Originally a commercial city of the Teutonic Order, it received town rights in 1346. It prospered as a grain and timber centre until it was devastated in the 17th-century Swedish wars. In the 18th century the Bydgoszcz Canal, which linked the basins of the Vistula and Oder rivers, made the city a major inland port. It fell under Prussian rule in 1772–1919. The Germans held it throughout World War II, but it was noted for its staunch resistance to the Nazi invasion of 1939. It remains important as a water transport route, connecting Upper Silesia with the Baltic ports.

Thanks to its location between Vistula and Odra water system on the Bydgoszcz channel, the city is an important link in a water system connected via Noteć, Warta, Odra, Elbe with the Rhine and Rotterdam.
In the 15th-16th centuries Bydgoszcz was a significant site for corn trading. The Treaty of Bydgoszcz was signed in the city in 1657.
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 and, later, West Prussia. During this time, a canal was built from Bydgoszcz 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 Bydgoszcz 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, Bydgoszcz was annexed to Poland in 1919. It shifted in 1938 to the Pomeranian Voivodeship.
From 1939-45 during World War II, Bydgoszcz was overrun by Nazi Germany and annexed to the Reichsgau Wartheland. On September 3 1939, shortly after the war started, the Bromberg Bloody Sunday incident occurred in which numerous Poles and Germans were killed; the incident was used by Nazi propaganda for retaliation against Poles after Bydgoszcz was occupied by the Wehrmacht on September 9. The city's Jewish citizens were repressed, as thousands of people were sent to concentration camps and/or executed. Bydgoszcz was the site of Bromberg-Ost, a female subcamp of Stutthof. The subcamp staffed several female SS guards (Aufseherin) and was commanded by the Oberaufseherin Johanna Wisotzki and a male commandant. A deportation camp was situated in Smukała village, now part of Bydgoszcz. According to Nowa encyklopedia powszechna PWN, 37,000 citizens of the city died during the war. 
In 1945 Bydgoszcz was liberated and annexed again to Poland.
In 1981 Solidarity's activists were violently suppressed in Bydgoszcz.
