A comprehensive study of the areas that make up the current landscape of Bohuslän from a settlement, agricultural and economic history perspective. The project is not only comprehensive in terms of the time period studied but also in terms of the level of detail. All available source material for the period is examined, including not only traditional historical sources such as land registers, laws, diplomas, literary sources, maps, etc. but also archaeological material, place names, dialect research, ethnographic sources, art historical material (mainly churches) and some sources of a scientific nature. The results of the project are published in two volumes: a volume dealing with the period from a more general perspective and a volume with detailed settlement and agricultural history maps and tables at parish level. The two works together contain over 100 maps and some 50 pictures/illustrations. The project is not only regional historical, but the geographical location of the area inevitably means that the general historical development in Scandinavia during the period is taken into account.
