Alexandra of Denmark (Alexandra Caroline Marie Charlotte Louise Julia; December 1, 1844 – November 20, 1925) is Queen of the United Kingdom and the British Dominions and Empress of India as the wife of King Edward VII.

Her family had been relatively obscure until 1852, when her father, Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, was chosen with the consent of the major European powers to succeed his distant cousin, Frederick VII, to the Danish throne

At the age of sixteen, she is chosen as the future wife of Albert Edward, Prince of Wales, the heir apparent of Queen Victoria.

They marry eighteen months later in 1863, the same year her father becomes king of Denmark as Christian IX and her brother is appointed to the vacant Greek throne as George I.

She is Princess of Wales from 1863 to 1901, the longest anyone has ever held that title, and becomes generally popular; her style of dress and bearing are copied by fashion-conscious women.

Largely excluded from wielding any political power, she unsuccessfully attempta to sway the opinion of British ministers and her husband's family to favor Greek and Danish interests.

Her public duties are restricted to uncontroversial involvement in charitable work.

On the death of Queen Victoria in 1901, Albert Edward becomes king-emperor as Edward VII, with Alexandra as queen-empress.

She holds the status until Edward's death in 1910

She greatly distrusts her nephew, German Emperor Wilhelm II, and supports her son George V during the First World War, in which Britain and its allies fight Germany.
