The map of Denmark has changed throughout history by expanding and contracting as the country absorbed other territories and lands before losing them. The country once controlled parts of England and Ireland in the 9th century, and up until the 1900s, Iceland remained part of Denmark's territory.
The earliest map of Denmark starts with the land settled and controlled by the Danish vikings between 800 and 1100 B.C. that included Danelaw, which consisted of areas now part of Ireland, England, Iceland, Greenland, parts of France and various islands. Although Denmark lost England in 1035, it conquered Baltic city-states, including regions in Russia, Germany, Poland and Sweden. However, civil war again reduced the size of the nation.
By the 1400s, Denmark united with other Scandinavian countries such as Norway, Sweden and Finland, but the unification fell apart. By the 1500s, Denmark's map had changed again to include just Denmark itself, Norway and parts of Sweden. During the 1600s, Denmark gained and lost land during its ongoing feud with Sweden, particularly many of its territories in Norway. The country gained some territory in northern Germany and the islands of the West Indies in the 1700s. During the 1800s, Denmark became allied with Napoleonic France, but had to give up Norway at Napoleon's defeat.
The Danish map changed once again in the 1900s when its long-held territories, Iceland and Greenland, gained their independence.
