Queen Victoria of the United Kingdom marries Prince Albert of Saxe-Coburg-Gotha.

Prince Albert of Saxe-Coburg and Gotha (Francis Albert Augustus Charles Emmanuel; 26 August 1819 14 December 1861) was the consort of Queen Victoria from their marriage on 10 February 1840 until his death in 1861.

Albert was born in the Saxon duchy of Saxe-Coburg-Saalfeld to a family connected to many of Europe's ruling monarchs. At the age of twenty, he married his first cousin Victoria; they had nine children. Initially he felt constrained by his role as consort, which did not afford him power or responsibilities. He gradually developed a reputation for supporting public causes, such as educational reform and the abolition of slavery worldwide, and was entrusted with running the Queen's household, office, and estates. He was heavily involved with the organisation of the Great Exhibition of 1851, which was a resounding success.

Victoria came to depend more and more on Albert's support and guidance. He aided the development of Britain's constitutional monarchy by persuading his wife to be less partisan in her dealings with Parliamentalthough he actively disagreed with the interventionist foreign policy pursued during Lord Palmerston's tenure as Foreign Secretary. Albert died in 1861 at age 42, devastating Victoria so much that she entered into a deep state of mourning and wore black for the rest of her life. On her death in 1901, their eldest son succeeded as Edward VII, the first British monarch of the House of Saxe-Coburg and Gotha, named after the ducal house to which Albert belonged.

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 in 1901. Known as the Victorian era, her reign of 63 years and seven months was longer than any previous British monarch. It was a period of industrial, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire. In 1876, the British Parliament voted to grant her the additional title of Empress of India.

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 the deaths of her father and grandfather 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. Though a constitutional monarch, Victoria privately 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 first 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, British republicanism 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.
