As Queen from 1901 to 1910, and Queen Mother thereafter, Alexandra was greatly loved by the British people. During the
Boer War, she founded
Queen Alexandra's Nursing Corps, which became known as the "Q.A.s". She had a distinct dislike of the Germans, a hatred that stemmed from the Prussian conquest of the formerly Danish lands
Schleswig and
Holstein during the
Second War of Schleswig in 1864. For this reason, biographers have asserted that she was denied access to the King's briefing papers and excluded from some of the King's foreign tours in order to prevent her meddling in diplomatic matters. The
Frankfurter Zeitung was outspoken in its condemnation of Alexandra and her sister, Dagmar, Dowager Empress of Russia, saying that the pair were "the centre of the international anti-German conspiracy". She despised and distrusted her nephew,
William II of Germany, calling him in 1900 "inwardly our enemy".
In 1907, Alexandra and Dagmar purchased a villa north of Copenhagen, Hvidore, as a private getaway. In 1910, Alexandra was visiting her brother, George I of Greece, in
Corfu when she received news that the King was seriously ill. Alexandra returned at once, and arrived just the day before her husband died. In his last hours, she personally administered him oxygen from a gas cylinder to help him breathe. She told
Frederick Ponsonby, "I feel as if I had been turned into stone, unable to cry, unable to grasp the meaning of it all." Later that year, she moved out of
Buckingham Palace to
Marlborough House, but she retained possession of Sandringham; she did not attend her son's coronation in 1911 but otherwise continued the public side of her life, devoting time to her charitable causes, one of the most notable being
Alexandra Rose Day, where artificial roses made by the disabled were sold in aid of hospitals by women volunteers.
During the
First World War, it is said that her son,
George V, ordered all the
Order of the Garter arms of those who fought for
Germany removed from
St. George's Chapel, Windsor at her insistence. A further reason for expelling the Germans from the Order of the Garter was that a Knight of the Garter swears an oath never to take up arms against the British Sovereign. During the First and Second World Wars, this became an embarrassing mockery, and the German members of the Order were expelled therefrom in 1915 in a solemn ceremony at St. George's Chapel. During the Second World War, Hirohito, the Emperor of Japan, was also expelled from the Order. Today, the Order of the Garter, the bestowing of which is the exclusive gift and prerogative of the Sovereign, is awarded much more sparingly. In Russia, Tsar Nicholas II was overthrown and he, his wife and children were killed by revolutionaries. The Dowager Empress, Dagmar, Alexandra's sister, was rescued from Russia in 1919 by a British warship,
HMS Marlborough, and brought to England where she lived for some time with her sister.
Like many royals of her generation, Queen Alexandra had no understanding of money despite the endeavours of her loyal Comptroller, Sir Dighton Probyn VC, who had a similar role when her husband was Prince of Wales and later as King Edward VII.
Alexandra remained youthful looking into her senior years, thanks to elaborate veils and very heavy makeup (an observer described her as looking enamelled). She died on
20 November 1925 after suffering a
heart attack, at
Sandringham, and was buried in an elaborate tomb next to her husband in St. George's Chapel at
Windsor.
