Magnus IV of Sweden
In the early part of the 13th century the province of Halland was part of Denmark. The Danish kings had built a fortification on the east shore of the Ätran river in the community of Falkenberg. The fort was the site for several Nordic treaties during the fourteenth century. It was burnt down by Count Erik Magnusson (c. 1282 – 1318) in 1356 during his revolt against his father King Magnus IV of Sweden.
