Danish nobility in the context of Reformation in Denmark–Norway and Holstein

The Baltic German nobility was a privileged social class in the territories of modern-day Estonia and Latvia. It existed continuously from the Northern Crusades and the medieval foundation of Terra Mariana.

Most of the nobility consisted of Baltic Germans, but with the changing political landscape over the centuries, Polish, Swedish, Russian, Danish, and even Scottish families also became part of the nobility, just as Baltic German families re-settled in locations such as the Swedish and Russian Empires. The nobility of Lithuania is for historical, social and ethnic reasons separated from the German-dominated nobility of Estonia and Latvia.

Krebs School (Danish: Krebs' Skole) is a private school located in Stockholmsgade in Copenhagen, Denmark. It was founded on 15 August 1872 by Conrad Peter Julius Krebs. Several members of the Danish royal family have attended the school, along with other members of the Danish upper class and nobility. As of 2023, the school's headmaster is Mikael Fink-Jensen.

Count of Monpezat (Danish: Greve af Monpezat), or Countess of Monpezat (Danish: Komtesse af Monpezat) when the holder is female, is a hereditary title of Danish nobility. It was granted on 30 April 2008 by Queen Margrethe II to her two sons, Crown Prince Frederik and Prince Joachim, and their legitimate patrilineal (male-line) descendants. The title is derived from the French title of "comte de Laborde de Monpezat", which was used by Frederik and Joachim's father, Prince Henrik. His family started using this title as a title of pretense in republican France in the late 19th century.

The title can only be passed down the male line, but unmarried daughters of a count hold the courtesy title komtesse (derived from the French word for countess). The wife of a count holds the courtesy title grevinde (the Danish word for countess). A komtesse (a count's daughter) cannot pass on the title to her husband or children.

Sophie of Mecklenburg-Güstrow (Sophia; 4 September 1557 – 4 October 1631) was Queen of Denmark and Norway from 1572 to 1588 as the wife of Frederick II. She was the mother of Christian IV and Anne of Denmark, and served as regent of the duchies of Schleswig and Holstein from 1590 to 1594. Especially noted for her effective management of her extensive dower lands and a large credit operation, which made her one of the wealthiest landowners and financiers of her time, she was an influential political figure in Northern Europe.

The only child of Ulrich III of Mecklenburg-Güstrow and Elizabeth of Denmark, Sophie married her first cousin Frederick in 1572, aged fourteen. Their union is widely described as unusually affectionate for the period. As queen, she maintained her own household and patronages and pursued interests in natural philosophy, astrology, alchemy, chemistry and iatrochemistry. She supported scholars including Anders Vedel and Tycho Brahe, whom she visited on Ven in 1586 and later. She did not, however, exercise formal political power during the reign of her husband. Following Frederick’s death in 1588, Sophie sought to lead the regency for the underage Christian IV, bringing her into conflict with the Council of the Realm. Although she did not prevail in directing the royal regency, she was recognised by the Danish nobility and Emperor Rudolf II as regent in the duchies until 1594, after which she withdrew to her dower lands, consisting of Lolland and Falster. From there she continued to intervene in affairs of state through correspondence, credit, and marriage diplomacy, arranging advantageous Protestant alliances for her daughters and for Christian IV with the houses of Stuart, Welf (Brunswick-Lüneburg), Hohenzollern (Brandenburg), Holstein-Gottorp and Wettin (Saxony), often contributing substantial funds for jewellery and dowries herself.

Briefadel (in German; pronounced [ˈbʁiːfʔaːdl̩]) or brevadel (in Danish, Norwegian, and Swedish) is a medieval German term for persons or families ennobled by letters patent. The oldest known such letters patent were issued in the middle of the 14th century, during the Late Middle Ages.

Briefadel can be contrasted with Uradel, whose nobility predates issuance of letters patent. The term dates to the early nineteenth century.
