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 Helena of the United Kingdom

Helena was educated by private tutors chosen by her father and his close friend and adviser, Baron Stockmar.
Her childhood was spent with her parents, travelling between a variety of royal residences in Britain.
The intimate atmosphere of the royal court came to an end on 14 December 1861, when her father died and her mother entered a period of intense mourning.
Afterwards, in the early 1860s, Helena began a flirtation with Prince Albert's German librarian, Carl Ruland.
Although the nature of the relationship is largely unknown, Helena's romantic letters to Ruland survive.
After the Queen found out in 1863, she dismissed Ruland, who returned to his native Germany.
Three years later, on 5 July 1866, Helena married the impoverished Prince Christian of Schleswig-Holstein.
The couple remained in Britain, in calling distance of the Queen, who liked to have her daughters nearby.
Helena, along with her youngest sister, Princess Beatrice, became the Queen's unofficial secretary.
However, after Queen Victoria's death on 22 January 1901, Helena saw relatively little of her surviving siblings, including King Edward VII.
Helena was the most active member of the royal family, carrying out an extensive programme of royal engagements.
She was also an active patron of charities, and was one of the founding members of the British Red Cross.
She was founding president of the Royal School of Needlework, and president of the Workhouse Infirmary Nursing Association and the Royal British Nurses' Association.
As president of the latter, she was a strong supporter of nurse registration against the advice of Florence Nightingale.
In 1916 she became the first member of her family to celebrate her 50th wedding anniversary, but her husband died a year later.
Helena outlived him by six years, and died aged 77 at Schomberg House on 9 June 1923.
