In December 1672, King Charles XI came to age. Despite what people might have anticipated, De la Gardie now became mightier than ever before. The young and inexperienced king seems to have been glad to take the advice of his Lord High Chancellor De la Gardie, who tried to increase the king's power in order to increase his own. However, from 1675, his influence decreased. That year, bound by the treaty with France, Sweden entered the Franco-Dutch War by invading Brandenburg. Although being numerically superior, the Swedish forces lost at Fehrbellin, which led to Denmark being encouraged to attack Sweden. Thus, the Scanian War was initiated. In connection with King Charles's coronation the same year, De la Gardie was accused of high treason, an accusation that soon was judged as unjustified.
