Magnus IV of Sweden
The independence and privileges of the county were founded by the "Joninpoika" brothers. Squire Peter Jonsson (later knighted) and his elder brother sir Sune Jonsson, Lord of Flishult, Royal Councillor, the lawspeaker of Tiohärad (in inland Småland), together with their close relative Charles, bishop of Linköping, allies of the new king Magnus IV of Sweden, in 1320 or 1321 purchased "dominus Efflerus", the bailiff of the deposed king Birger of Sweden, out from Viborg castle. They committed to keep the castle and its revenues for bishop Charles until the purchase price be compensated.
