Treaties of Tilsit
As a result of the First Partition of Poland in 1772 the Kingdom of Prussia took a considerable part of Inowrocław and the western part of Brześć-Kujawy as part of the Netze District. After the Second Partition of 1793 the whole of Kuyavia was taken by Prussia and incorporated into the South Prussia province. Upon the 1807 Treaties of Tilsit, it was part of the Napoleonic Duchy of Warsaw and administrated within the Bydgoszcz Department.
