Frederik IV reigned from 1699 until 1730. None of the other absolute monarchs in Danish history ruled in as headstrong a fashion as he did. Frederik IV took it upon himself to make as many of the realm's decisions as possible himself, and this worked remarkably well. With the help of Tordenskjold, he brought Denmark-Norway safely through the bloody Great Northern War, which would be Denmark's final showdown with its archenemy Sweden. In his love life, too, he was extremely headstrong; he abducted his beloved Anna Sophie Reventlow, with whom he entered into a morganatic marriage and whom he later made his Queen.
