Christian VI (30 November 1699 – 6 August 1746) was King of Denmark and Norway from 1730 to 1746. The eldest surviving son of Frederick IV and Louise of Mecklenburg-Güstrow , he is considered one of Denmark-Norway 's more anonymous kings, but he was a skilled politician, best known for his authoritarian regime.
Christian's mother, Helvig, was a daughter of Gerhard VI, Count of Holstein, and a sister of Adolphus, Duke of Schleswig. Through his mother, Christian was also a cognatic descendant of King Eric V of Denmark through his second daughter Richeza (died 1308) and also a cognatic descendant of King Abel of Denmark through his daughter Sophie.
Christian IX was born on 8 April 1818 at the residence of his maternal grandparents, Gottorf Castle, near the town of Schleswig in the Duchy of Schleswig. Born as a prince of Schleswig-Holstein-Sonderburg-Beck, he was the fourth son of Friedrich Wilhelm, Duke of Schleswig-Holstein-Sonderburg-Beck, and Princess Louise Caroline of Hesse-Kassel.
Christian's Protestant policies led Denmark toward the establishment of Lutheranism as the Danish National Church (Folkekirke). This occurred officially on 30 October 1536 when the reconstituted State Council adopted the Lutheran Ordinances designed by German theologian Johannes Bugenhagen (1485–1558), which outlined church organization, liturgy, and accepted religious practice.
Christian VIII (18 September 1786 – 20 January 1848) was King of Denmark from 1839 to 1848 and, as Christian Frederick, King of Norway in 1814.  Christian Frederick was the eldest son of Hereditary Prince Frederick , a younger son of King Frederick V of Denmark and Norway.
Christian X quickly realized that Denmark was in an impossible position. Its territory and population were far too small to hold out against Germany for any sustained period of time. Its flat land would have resulted in it being easily overrun by German panzers ; Jutland , for instance, would have been overrun in short order by a panzer attack from Schleswig-Holstein immediately to the south.
Christian V (15 April 1646 – 25 August 1699) was king of Denmark and Norway from 1670 until his death in 1699.. Well-regarded by the common people, he was the first king anointed at Frederiksborg Castle chapel as absolute monarch since the decree that institutionalized the supremacy of the king in Denmark-Norway.
