from wikipedia:
Denmark tried to regain control of Skåne in the Scanian War (1675-79) but this attempt was a failure. Following the Great Northern War (1700–21), Denmark managed to restore control of the parts of Schleswig and Holstein ruled by the house of Holstein-Gottorp in 1721 and 1773, respectively. Denmark prospered greatly in the last decades of the 18th century due to its neutral status allowing it to trade with both sides in the many contemporary wars. In the Napoleonic Wars, Denmark originally tried to pursue a policy of neutrality to continue the lucrative trade with both France and the United Kingdom and joined the League of Armed Neutrality with Russia, Sweden and Prussia. The British considered this a hostile act and attacked Copenhagen in both 1801 and 1807, in one case carrying off the Danish fleet, in the other, burning large parts of the Danish capital.
