Denmark has an area of about 43,100 square kilometers (excluding Greenland and Faroe Islands ). There is Germany, the only land neighbor in the south, and it faces Sweden across the Katgart Strait in the northeast.

Before the opening of the Kiel Canal in Germany, Denmark locked and controlled the sea channel from the Baltic Sea to the Atlantic North Sea, occupying a unique geographical advantage. The three major islands between the Jutland Peninsula and Scandinavia Peninsula , Zeland Island , Feiying Island , and Lorrain Island all belong to Denmark. These three islands are also connected by bridges, locking the Great Belt Strait and Ore Strait .
Denmark capital Copenhagen , not on the European continent, it is located on the island of Zeland. There is a bridge between Denmark's island of Zeeland and Sweden, called Ore Strait Bridge . Connecting the Denmark capital Copenhagen to the Swedish city of Malmö , the European E20 Highway passes on the bridge.

After the opening of the Kiel Canal in Germany, the ship can go directly from the Kil Bay in the Baltic to the North Sea, with a voyage greatly shortened. After many expansions and expansions, the Kiel Canal allows ships to be up to 32.5 meters wide, up to 235 meters long, and a tonnage of up to 74,000 tons. It is fine for most ships to pass through. Denmark suffered a head-on blow in sea transportation.
Denmark has a population of about 5.825 million (September 2020), with a small place and a small population, but it laid a good foundation during the colonial period and has more than 2 million square kilometers of territory overseas.

Denmark has sovereignty over Greenland and the Faroe Islands, but these two places are generally not included in Denmark's territory. Denmark is a member of the EU , but Greenland and the Faroe Islands are not in the EU and have a high degree of autonomy. If Denmark is compared to the United Kingdom, Greenland and the Faroe Islands have higher autonomy than Scotland and , which is equivalent to Australia and Canada before independence from Britain.
Greenland is mainly composed of Greenland . Including the attached islands, the area is about 2.1661 million square kilometers. Greenland is the largest island in the world, located between Arctic Ocean and Atlantic Ocean , and is located in northeastern North America. The closest country to Greenland is Canada, which is across Baffin Bay and Davis Strait from Canada's Arctic islands; followed by Iceland , which is across Danish Strait from Iceland. Greenland belongs to North America, most of which are located within Arctic Circle . The climate is extremely cold and the population is about 56,000 (2019).

Since 2009, Greenland has become an independent political entity under international law, managing its internal affairs, judicial and resource allocation and application, but its national defense, diplomacy and finance related affairs are still under the jurisdiction of Denmark.
In 2019, the United States proposed to Denmark the possibility of buying Greenland. Denmark refused, but was scared, and even Russia was nervous.

Faroe Islands are composed of 18 major islands, with a land area of about 1399 square kilometers and a population of about 50,000. The Faroe Islands are about 450 kilometers away from Iceland, about 320 kilometers away from the Scottish coast of the United Kingdom, about 670 kilometers away from the Norwegian coast, and about 990 kilometers away from the mainland of Denmark. They are located at a maritime crossroads and have an extremely important strategic location.
WWII, the British army occupied the Faroe Islands. After World War II, Britain wanted to obtain the Faroe Islands from Denmark, but it was severely rejected, but the British directed an independence referendum for the Faroe Islands.

11946, the Faroe Islands launched an independence referendum, with 50.74% of the votes supporting independence. Of course Denmark would not agree, but was forced to give in. As long as the British could be driven away, other conditions would be easy to say.
1948, the Faroe Islands were no longer a direct county in Denmark, but became a Denmark overseas autonomous territory with a high degree of autonomy. And Britain was also happy and finally left in a mess.

Denmark controls 2.1661 million square kilometers of Greenland and 1,399 square kilometers of Faroe Islands with 43,100 square kilometers of territory overseas.
