From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systems The shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil. In sandy soils, and other fine soils, the ard will at each turn deposit small amounts of roots, soil and debris at the edge of the field, which over the years will build up the walls of the celtic fields. But in boulder-rich soil the ard will constantly have to be lifted and tilted, which means that the material will be released before the ard reaches the edge of the field. Since crops, vegetation, houses, field system areas, etc. are identical or at least similar in both landscape types, they most likely represent the same farming system with hay-meadow – stabling – manure – intensely cultivated fields In most provinces in southern Sweden, the pre-roman celtic fields and clearance cairn areas were replaced by geometrically laid-out strip fields or different kinds of stone-wall complexes enclosing the fields and farms, around AD 200, but not in Småland. There, the clearance cairn areas were used and extended throughout the Iron Age. How can this regional variation be explained? A comparison between the different landscape types reveals no significant differences in tools, crops, houses, etc. that would support that the difference is explained by a shift in farming systems. A more likely hypothesis is that the difference is due to regional pre-state or early-state political structures with an ambition to control land-use. This is based on the observations that 1) within each region the physical appearance of the fossil landscape is very coherent; 2) between the different regions there are significant differences, and; 3) the different systems were introduced approximately simultaneously in the regions Gotland, Öland, Östergötland, Uppland and Västergötland. This hypothesis implies that Småland either had a separate political structure which chose to keep the old clearance cairn land-use system, or lacked a corresponding regional structure.
