Victoria 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.

Victoria inherited the throne at the age of 18, after her father's three elder brothers had all died leaving no surviving legitimate children. She became a national icon who was identified with strict standards of personal morality. Victoria married her first cousin Prince Albert. After his death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result, 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.

William Ewart Gladstone (29 December 1809 – 19 May 1898) was a British statesman and Liberal Party politician. In a career lasting over sixty years, he served for twelve years as Prime Minister of the United Kingdom, spread over four terms beginning in 1868 and ending in 1894.

Many reforms were passed during his first ministry, including the disestablishment of the Church of Ireland and the introduction of secret voting. After electoral defeat in 1874, Gladstone resigned as leader of the Liberal Party.
