Queen Margaret I, who had just founded the Kalmar Union (consisting of Denmark, Norway, Sweden, Iceland, Greenland, Faroe Islands, Shetland, Orkney, parts of Finland and parts of Germany) ordered the building of a navy — mainly to defend the union against the Hanseatic League.
Until the copenhagenization of the navy in 1807, the navy was a major strategic influence in the European geographical area, but since then its size and influence has drastically declined with a change in government policy.
Despite this, the navy is now equipped with a number of large state-of-the-art vessels commissioned since the end of the Cold War.
In the period after the Vikings, and up to the 15th century, the fleet consisted mainly of merchant vessels.
Indeed, it is said that king Valdemar Sejr had more than 1,000 ships during the conquest of Estonia in 1219.
They were often based in a small number of villages, usually with a common defence agreement; Viking ships, usually of the Knarr type, were light, and therefore easy to transport from village to village over land.
