Princess Louise Charlotte of Denmark (30 October 1789 – 28 March 1864) was a princess of Denmark.

She was born in Christiansborg Palace to Hereditary Prince Frederick of Denmark and Norway and Sophia Frederica of Mecklenburg-Schwerin (1758–1794), Princess and Duchess of Mecklenburg-Schwerin.

On 10 November 1810 in Amalienborg Palace she married Wilhelm, Landgrave of Hesse-Kassel. They were parents to:

She was described as practical and economic, with some interest for art and poetry, and held a strict economic control over her court. On 18 July 1851, she and her son renounced their claim to the Danish throne to her daughter, who in turn renounced it to her spouse.

Louise Charlotte is the matrilineal great-grandmother of Nicholas II of Russia, William IV, Grand Duke of Luxembourg and George V.

She died in Christiansborg Palace.

The Kingdom of Denmark (Danish: Kongeriget Danmark, pronounced [ˈkɔŋəʁiːəð ˈdanmɑɡ̊] ( listen)) is a constitutional monarchy and sovereign state consisting the country of Denmark in northern Europe and two autonomous constituent countries, the Faroe Islands in the North Atlantic and Greenland in North America. The kingdom is a unitary state with some power being devolved from Denmark proper to Greenland and the Faroe Islands; this polity is referred to as the Danish Realm. Denmark proper is the hegemonial area, where judicial, executive, and legislative power resides. The Faroe Islands are defined to be a community of people within the kingdom, and the Greenlandic people are defined as a separate people with the right to self-determination.

Denmark is the southernmost of the Nordic countries, located southwest of Sweden and south of Norway, and bordered to the south by Germany. The country consists of a large peninsula, Jutland and many islands, most notably Zealand, Funen, Lolland, Falster and Bornholm, as well as hundreds of minor islands often referred to as the Danish Archipelago.

Princess Louise Caroline of Hesse-Kassel (28 September 1789, Gottorp, Schleswig, Duchy of Schleswig – 13 March 1867, Ballenstedt, Germany) was the consort of Friedrich Wilhelm, Duke of Schleswig-Holstein-Sonderburg-Glücksburg and the matriarch of the House of Schleswig-Holstein-Sonderburg-Glücksburg which would eventually become the ruling house of the kingdoms of Denmark, Greece, Norway, and, barring unforeseen circumstances, the United Kingdom.

Louise Caroline was born at Gottorp in the Duchy of Schleswig to Landgrave Charles of Hesse-Kassel (19 December 1744 – 17 August 1836) and his wife Princess Louise of Denmark (30 January 1750 – 12 January 1831). Her elder sister Marie Sophie of Hesse-Kassel (28 October 1767 – 21 March 1852) became Queen consort of Frederick VI of Denmark.

Friedrich Wilhelm and Louise Caroline had ten children:

Louise Caroline's son, Prince Christian, was named third-in-line to the throne of Christian VIII of Denmark in 1847. He succeeded his childless cousin, Frederick VII of Denmark, on 15 November 1863, the Hereditary Prince Ferdinand having deceased somewhat earlier.

Princess Frederica Louise Wilhelmina Marianne Charlotte of Prussia (21 June 1831 – 30 March 1855) was the eldest daughter of Prince Albert of Prussia and his wife Princess Marianne of the Netherlands. She died before her husband Georg of Saxe-Meiningen could succeed as Duke, making her Hereditary Princess of Saxe-Meiningen.

Charlotte's father Albert was a younger son of Frederick William III of Prussia and Louise of Mecklenburg-Strelitz. Her mother Marianne was a daughter of William I of the Netherlands and Wilhelmine of Prussia. Charlotte was a sister of Prince Albert of Prussia, a Prussian general field marshal and later regent of the Duchy of Brunswick.

Her parents divorced in 1848, and custody of Charlotte and her siblings was given to her father. In actuality, their childless aunt Queen Elisabeth Ludovika (wife of Frederick William IV of Prussia) took care of them.

Charlotte had a talent for music, and was taught by the likes of Wilhelm Taubert, Theodor Kullak, and Julius Stern in her youth. She wrote a number of military marches, songs, and piano pieces. Her daughter Princess Marie Elisabeth would inherit these interests.

Alexandra of Denmark (Alexandra Caroline Marie Charlotte Louise Julia; 1 December 1844 – 20 November 1925) was the wife of King Edward VII of the United Kingdom and the British Dominions. As such, she was queen consort and Empress of India from 1901 to 1910.

Her family had been relatively obscure until her father, Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, was chosen with the consent of the great powers to succeed his distant cousin, Frederick VII, to the Danish throne. At the age of sixteen, she was chosen as the future wife of Albert Edward, Prince of Wales, the heir apparent of Queen Victoria. They married eighteen months later in 1863, the same year her father became Christian IX of Denmark and her brother, George, was appointed King of Greece. She was Princess of Wales from 1863 to 1901, the longest anyone has ever held that title, and became generally popular; her style of dress and bearing were copied by fashion-conscious women. Although largely excluded from wielding any political power, she unsuccessfully attempted to sway the opinion of British ministers and her husband's family to favour Greek and Danish interests. Her public duties were restricted to uncontroversial involvement in charitable work.
