Queen Victoria
Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death.
On 1 May 1876, she adopted the additional title of Empress of India.
Known as the Victorian era, her reign of 63 years and seven months was longer than that of any of her predecessors.
It was a period of industrial, cultural, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire.
Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld.
After both the Duke and his father died in 1820, she was raised under close supervision by her mother and her comptroller, John Conroy.
She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue.
The United Kingdom was an established constitutional monarchy in which the sovereign held relatively little direct political power.
Privately, she attempted to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.
Victoria married her cousin Prince Albert of Saxe-Coburg and Gotha in 1840.
Their children married into royal and noble families across the continent, earning Victoria
the sobriquet "the grandmother of Europe" and spreading haemophilia in European royalty.
After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances.
As a result of her seclusion, republicanism in the United Kingdom temporarily gained strength, but in the latter half of her reign, her popularity recovered.
Her Golden and Diamond Jubilees were times of public celebration.
She died on the Isle of Wight in 1901.
The last British monarch of the House of Hanover, she was succeeded by her son Edward VII of the House of Saxe-Coburg and Gotha.

Princess Louise, Duchess of Argyll
Princess Louise, Duchess of Argyll, (Louisa Caroline Alberta; 18 March 1848 – 3 December 1939) was the sixth child and fourth daughter of Queen Victoria and Prince Albert.
In her public life, she was a strong proponent of the arts and higher education and of the feminist cause.
Her early life was spent moving among the various royal residences in the company of her family.
When her father, the prince consort, died on 14 December 1861, the court went into a long period of mourning, to which with time Louise became unsympathetic.
Louise was an able sculptor and artist, and several of her sculptures remain today.
She was also a supporter of the feminist movement, corresponding with Josephine Butler, and visiting Elizabeth Garrett.
Before her marriage, from 1866 to 1871, Louise served as an unofficial secretary to her mother, the Queen.
The question of Louise's marriage was discussed in the late 1860s.
Suitors from the royal houses of Prussia and Denmark were suggested, but Victoria did not want her to marry a foreign prince, and therefore suggested a high-ranking member of the British aristocracy.
Despite opposition from members of the royal family, Louise fell in love with John, Marquess of Lorne, the heir of the Duke of Argyll.
Victoria consented to the marriage, which took place on 21 March 1871.
Despite a happy beginning, the two drifted apart, possibly because of their childlessness and the queen's constraints on their activities.
In 1878, Lorne was appointed Governor General of Canada, a post he held 1878–1884.
Louise was viceregal consort, starting a lasting interest in Canada.
Her names were used to name many features in Canada.
Following Victoria's death in 1901, Louise entered the social circle established by her elder brother, the new king, Edward VII.
Louise's marriage survived thanks to long periods of separation; the couple reconciled in 1911 and she was devastated by her husband's death in 1914.
After the end of the First World War in 1918, at the age of 70, she began to retire from public life, undertaking few public duties outside Kensington Palace, where she died at the age of 91.
