Stora Kopparbergs Bergslags Aktiebolag has its roots in Falun, Central Sweden, where copper mining began about a thousand years ago. Iron surpassed copper during the 18th century. In 1862 the operations were combined to form a single company, Stora Kopparbergs Bergslag, which became a limited company in 1888. Sawmilling, energy and pulp and paper production grew together with iron and steel production.
A fundamental step was taken in 1978 when Stora Kopparbergs Bergslags Aktiebolag (STORA) sold its iron and steel facilities and concentrated on energy and the forest industry. The expansion continued during the next two decades and in 1998 STORA and the Finnish company Enso Oyj were combined to form Stora Enso Oyj.
