The 19th century saw 20 thousand Polish soldiers interned after the failure of the November Uprising (1830–1831) and many townspeople and noblemen involved in the January Uprising (1863). It is in the Brodnica region too that Masovian insurgents sought refuge from Russian persecution after the failure of the January Uprising. Bank Spółdzielczy w Brodnicy, which is the oldest continuously operating Polish bank, was established in 1862. In 1873 a Polish philomath organization was founded in the local gymnasium, whose activity ended in 1901 due to Germany's anti-Polish policies.
