Sven Estridsson
Adam of Bremen describes Sweden, according to information he received from the Danish king Sven Estridson or also called Sweyn II of Denmark in 1068: "It is very fruitful, the earth holds many crops and honey, it has a greater livestock than all other countries, there are a lot of useful rivers and forests, with regard to women they do not know moderation, they have for their economic position two, three, or more wives simultaneously, the rich and the rulers are innumerable." The latter indicates a kind of extended family structure, and that forests are specifically mentioned as useful may be associated with shifting cultivation and livestock. The "livestock grazing, as with the Arabs, far out in the wilderness" can be interpreted in the same direction.
