Flag of Denmark in the context of "Flag"

A national church is a Christian church associated with a specific ethnic group or nation state. The idea was notably discussed during the 19th century, during the emergence of modern nationalism.

Samuel Taylor Coleridge, in a draft discussing the question of church and state around 1828 wrote that

The Battle of Lyndanisse or Lindanise was fought on 15 June 1219 during the Northern Crusades, between the forces of the invading Kingdom of Denmark and the local non-Christian Estonians. The Danish victory in the battle, at the site of the later Hanseatic city of Reval (now Tallinn, Estonia) helped King Valdemar II of Denmark to subsequently claim the territory of northern Estonia as his participation in the crusade into Estonia had been undertaken in response to calls from the Pope.

The 1219 Battle of Lyndanisse is still well known to this day, especially amongst Danes and Estonians, because of a popular legend about the first ever Danish flag, the Dannebrog, which allegedly fell from the sky, as an apparently helpful divine intervention, just when the Danish Crusaders were about to lose the battle to the local pagans.

Pituffik Space Base (/biːduːˈfiːk/ bee-doo-FEEK; Greenlandic: [pitufiːk]; IATA: THU, ICAO: BGTL), formerly Thule Air Base (/ˈtuːliː/), is a United States Space Force base located on the northwest coast of Greenland in the Kingdom of Denmark under a defense agreement between Denmark and the United States. Currently, 150 United States service members are stationed there, after the United States significantly reduced its presence from 6000 personnel during the Cold War. Denmark was a founding member of NATO in 1949, and the 1951 Greenland Defense Agreement allowed the United States to operate the base under a NATO framework, as long as both Denmark and the United States remain NATO members. Under the agreement, the Danish national flag must be flown at the base to recognize that the base is on Danish territory, but the United States is allowed to fly its own flag alongside the Danish flag on the facilities it operates.

It is the northernmost Department of Defense installation, 1,210 km (750 mi) north of the Arctic Circle and 1,524 km (947 mi) from the North Pole. Pituffik's Arctic environment includes icebergs in North Star Bay, two islands (Saunders Island and Wolstenholme Island), a polar ice sheet, and Wolstenholme Fjord. The base is home to a substantial portion of the global network of missile warning sensors of Space Delta 4, and space surveillance and space control sensors of Space Delta 2, providing space awareness and advanced missile detection capabilities to North American Aerospace Defense Command (NORAD), the United States Space Force, and joint partners.

The Order of the Dannebrog (Danish: Dannebrogordenen) is a Danish order of chivalry instituted in 1671 by Christian V, inspired by the legend that the Dannebrog flag fell from the sky in 1219. The Order's ribbon reflects the flag's colors, white and red, and the badge takes the form of the Dannebrog cross, as used in the royal coat of arms since the 17th century.

Until 1808, membership in the Order was limited to fifty members of noble or royal rank, who formed a single class known as White Knights to distinguish them from the Blue Knights who were members of the Order of the Elephant. In 1808, the Order was reformed and divided into four classes.
