The Kingdom of Denmark  commonly known as Denmark, is a country situated in the Scandinavian region of northern Europe. It is the southernmost of the Nordic countries. The mainland is bordered to the south by Germany; Denmark is located to the southwest of Sweden and the south of Norway. Denmark borders both the Baltic and the North Sea. The country consists of a large peninsula, Jutland (Jylland) and a large number of islands, most notably Zealand (Sjælland), Funen (Fyn), Vendsyssel-Thy, Lolland, Falster and Bornholm as well as hundreds of minor islands often referred to as the Danish Archipelago. Denmark has long controlled the approach to the Baltic Sea, and these waters are also known as the Danish straits. The Faroe Islands and Greenland are autonomous provinces of Denmark with home rule.

The earliest mention of a territory called "Denmark" is found in King Alfred the Great's modified translation into Old English of Paulus Orosius' Seven Books of History Against The Pagans ["Historiarum adversum Paganos Libri Septem"], written by Alfred when king of Wessex in the years 871-899. In a passage introduced to the text by Alfred, we read about Ohthere from Hålogaland’s travels in the Nordic region, during which 'Denmark [Denamearc] was on his [port side]... And then for two days he had on his [port side] the islands which belong to Denmark'. The earliest mention of the word "Denmark" within Denmark itself is found on the two rune stones at Jelling, believed to have been erected by Gorm the Old (c. 955) and Harald Bluetooth (c. 965). The larger stone of the two is often cited as Denmark's birth certificate, though both use the word "Denmark", in the form of (acc.) tanmaurk ['danm?rk] (large Jelling stone) and (gen.) tanmarkaR ['danmarka?] (small Jelling stone). The inhabitants of Denmark are there called tani ['dan?] ("Danes" in the acc.).

The earliest archaeological findings in Denmark date back to 130,000 – 110,000 BC in the Eem interglacial period. People have inhabited Denmark since about 12,500 BC and agriculture has been in evidence since 3,900 BC. The Nordic Bronze Age (1,800–600 BC) in Denmark was marked by burial mounds, which left an abundance of findings including lurs and the Sun Chariot. During the Pre-Roman Iron Age (500 BC – AD 1), native groups began migrating south, although the first Danish people came to the country between the Pre-Roman and the Germanic Iron Age, in the Roman Iron Age (AD 1–400). The Roman provinces maintained trade routes and relations with native tribes in Denmark and Roman coins have been found in Denmark. Evidence of strong Celtic cultural influence dates from this period in Denmark and much of northwest Europe and is among other things reflected in the finding of the Gundestrup cauldron. Historians believe that before the arrival of the precursors to the Danes, who came from the east Danish islands (Zealand) and Skåne and spoke an early form of north Germanic, most of Jutland and some islands were settled by Jutes. They were later invited to the British Isles as mercenaries by Brythonic king Vortigern, and were granted the south-eastern territories of Kent, the Isle of Wight, among other areas, where they settled. They were later absorbed or ethnically cleansed by the invading Angles and Saxons, who formed the Anglo-Saxons. The remaining population in Jutland assimilated in with the Danes, due territorial expansions from the south and the east, and the Jutes being initially weakened after their emigrations. The exact origins of the Danish nation have been lost in history. However, a short note about the Dani in "The Origin and Deeds of the Goths" from 551 by historian Jordanes is believed by some to be an early mention of the Danes, one of the ethnic groups from whom the modern Danish people are descended. The Danevirke defense structures were built in phases from the 3rd century forward, and the sheer size of the construction efforts in 737 are attributed to the emergence of a Danish king. The new runic alphabet was first used at the same time and Ribe, the oldest town of Denmark, was founded about 700 AD.

King Christian IV attacked Sweden in the 1611–13 Kalmar War but failed to accomplish his main objective of forcing Sweden to return to the union with Denmark. The war led to no territorial changes, but Sweden was forced to pay a war indemnity of 1 million silver riksdaler to Denmark, an amount known as the Älvsborg ransom. King Christian used this money to found several towns and fortresses, most notably Glückstadt (founded as a rival to Hamburg), Christiania (following a fire destroying the original city), Christianshavn, Christianstad, and Christiansand. Christian also constructed a number of buildings, most notably Børsen, Rundetårn, Nyboder, Rosenborg, a silver mine and a copper mill.
