Åtvidaberg (pron. Aat'vihda'bargh) is a locality and the seat of Åtvidaberg Municipality, Östergötland County, Sweden with 6,859 inhabitants in 2010. With the copper finds in the medieval age, a mining district was initiated. The town Åtvidaberg became the seat of a mining industry community. The town's development was to be directed by the noble family Adelswärd. Through investments in the 19th and early 20th century the town developed into a modern industrial town.
In the 1970s the industry was dominated by Facit, making calculators. It was a major sponsor of the football team Åtvidabergs FF, one of Sweden's strongest team in the 1970s. When Facit went bankrupt in the second half of the 1970s, it led to the downfall and degradation of the team.
