Until 1772 Krebsfelde was part of the Kingdom of Poland. The First Partition of Poland in 1772 resulted in the creation of a new province in 1773, called West Prussia, in which Krebsfelde was located in the Kreis of Elbing. In 1920, it became part of the territory of the Free City of Danzig. Since February 1945, Krebsfelde has been located in Poland. Today Krebsfelde (now Rakowiska) is a village in the administrative district of Gmina Nowy Dwór Gdański, within Nowy Dwór Gdański County, Pomeranian Voivodeship.
