The history of the city of Bydgoszcz reaches back to the 14th century, when King Casimir the Great gave the city its foundation privileges.

In the same year that the king granted the above-mentioned charter rights, the construction of the castle in Bydgoszcz commenced. Built in the area of 2,000 square meters, the castle was one of the biggest military buildings in the northern part of the Kingdom of Poland, and became the seat of the city’s authorities.

Louis I of Hungary bestowed upon Ladislaus of Opole power over the Lands of Kuyavia and Dobrzyń in 1379. By the end of the 14th century, however, the city would once again be directly ruled by the king. It is also worth mentioning that Queen Hedwig of Anjou paid the city of Bydgoszcz a visit in 1377.

The city began growing in importance soon after. By the beginning of the 15th century, Bydgoszcz owned ships, which enabled wheat trade with Gdańsk, making it an important medieval port.

1409 saw an act of treason on the part of the city’s patriciate, which ultimately lead to the Teutonic Order gaining control of the castle. Later, however, the city was recaptured by King Ladislaus Jagiello, who then handed over control of the city to Maciej of Łabiszyn, the Voivode of Brześć-Kuyavia. Additionally, a library in the Bernardine Monastery began operating.

16th century

As was the case in most cities the world over, there was a rise in the importance of merchants and craftsmen, who in the late Middle Ages founded an array of guilds. In 1522, a salt warehouse for the whole region was opened in Bydgoszcz. One year later, King Sigismund I the Old permitted the construction of the local water system, which lasted for three centuries.

The local treasury enjoyed its growth after Stanisław Kościelecki was allowed by the king to start charging a tariff of one grosz for each carriage that brought goods to the local market.

In the 16th century, local education developed.  In 1530, at the Bernardine Monastery, a school of philosophy was founded. Bartłomiej from Bydgoszcz, the author of a very popular Polish-Latin dictionary, gave lecturers there.

The beginning of the construction of public baths was mentioned for the first time in 1549. In 1577, King Stephen Bathory arrived in Bydgoszcz. While in the city, he issued the privilege of using one of each 60 pieces of rafting timber for repairing the bridges.

The opening of the local mint, located on Mill Island, was a crucial event in the city’s history. Private at first, and later transformed by King Sigismund III Vasa into the state mint, the institution was a very important factor in the development of the city.

17th century

Initially, the city was inhabited by 5,000 people. Thanks mostly to the Kościelecki family, the dynamic development of the city lasted until the second decade  of the century. In 1613, the Royal Mint was opened, the only such establishment in Poland in the years 1627-1644. Additionally, Pope Paul V founded the Poor Claire’s monastery in 1615, and two years later the Jesuits were brought to the city. The year 1624 was the begging of a very tragic period in the history of the city. A plague ravaged more than half of the population. 31 years later, Bydgoszcz was conquered by the Swedish army, who destroyed the Bydgoszcz castle one year later.

On  November 6, 1657, in the Old Town Market Square, a pivotal event in both the history of Poland and the city took place. Changing the power scheme in the whole of the country, the Welawa-Bydgoszcz treaty was signed by Jan Casimir and Frederick William I, ultimately leading to breaking of Poland’s dependency on the Kingdom of Prussia.

The Prussian army marched into Bydgoszcz in 1707, as did the Swedish army shortly after. In the wake of these invasions, the city was ravaged to such an extent that even the City Hall was burned to the ground. A decade later, another plague made its way to Bydgoszcz, which was by this point inhabited by 150 citizens. During the Seven Years’ War, the Prussian army captured the city yet again.

Franciszek Czacki, the royal cartographer, presented for the first time a blueprint for the construction of the Bydgoszcz Canal in 1766. Six years later, Bydgoszcz became a part of Prussia after the first partition of Poland in 1772. Consequently, the city became a part of the Noteć River Region under the Prussian crown. Unaffected by this swift change of political power, the construction of the Bydgoszcz Canal took another two years. Later, the first granaries were built, as well as a Protestant church.

In 1794, general Jan Dąbrowski captured Bydgoszcz, only to be forced to leave the city along with his army two weeks after his decisive victory.

19th century

At the turn of the century, the city was once again inhabited by 5,000 dwellers. The first printing house operated by Andrzej Fryderyk Grunauer was set up around this time.
 
The French army marched into the city in 1806. One year later, Bydgoszcz became a part of the Duchy of Warsaw. The city functioned as the seat of the departmental authorities.

Napoleon’s political downfall caused the city to once again be under Prussian rule. In 1815, the city became the capital of the Bydgoszcz Regency as part of the Grand Duchy of Poznań. Additionally, in the first decades of the 19th century, a public grammar school, as well as the Royal Classical Secondary School opened their doors to students. The first municipal hospital and a theatre were built around this time as well.

By the first half of the century, the city’s population surged to 10 thousand inhabitants. The Royal Director of the Eastern Railroads as well as the highest authorities of the Royal Post were located in the city at the time. Between 1851-1861 the city was granted rail connections with cities such as Berlin, Szczecin, Gdańsk, Warsaw and Toruń. What is more, in 1865, the first mini network made up of 60 telephones was set up in the city. It is also worth mentioning that the city itself was illuminated by no fewer than 300 gas lamps after dusk at the time.

Bydgoszcz’s population would swell to 35 thousand inhabitants by 1888. In the same year, the first horse-powered streetcars began operating in the city’s streets. By the end of the 19th century, a power station, children’s hospital, slaughterhouse, a new theater, as well as a water station were built in the city.

20th century

Bydgoszcz underwent a period of rapid growth at the beginning of the 20th century. With a population of 50 thousand, the first decade of the 20th century saw the opening of the city’s first steel bridge, municipal library, as well as an emergency room in the municipal hospital. Statues depicting the Deluge and one of the city’s symbols, the Archeress, were too unveiled around this time. In 1919, Bydgoszcz once again became a part of Poland under the Treaty of Versailles.

On September 1, 1939, the German Lufftwaffe made its first air raid on the city. In the days that followed, a mass murder of both Germans and Poles took place. Bydgoszcz later became a part of the German Reich, and the then mayor, Barciszewski, was murdered by the Nazis. In total, 37 thousand citizens of Bydgoszcz lost their lives during the war.

By the end of 1945, Bydgoszcz’s population counted 135 thousand inhabitants. On September 11, 1946, the Leon Wyczółkowski District Museum opened its doors to the general public.

Śniadecki University of Technology and Life Sciences, on the other hand, was established in place of the former Academy of Technology and Agriculture. It is worth mentioning that these two establishments of higher education are the first two universities in the city’s history.

At the beginning of the new millennium, a number of crucial investments for the city’s sporting infrastructure were carried out.
