Queen Victoria narrowly escapes an assassination attempt by Roderick McLean in Windsor.

Roderick Edward Maclean (c.1854 8 June 1921) was a Scotsman who attempted to assassinate Queen Victoria on 2 March 1882, at Windsor, England, with a pistol. This was the last of eight attempts by separate people to kill or assault Victoria over a period of four decades. Maclean's motive was purportedly a curt reply to some poetry that he had mailed to the Queen.

The attempted murder followed the arrival of the Royal train, conveying the Queen, Princess Beatrice and the Court from Windsor. Queen Victoria had just walked across the platform of Windsor station to a carriage in waiting when Maclean, who was standing at the entrance of the station yard among a number of spectators, deliberately fired a revolver at her. The shot missed, and Maclean was seized by Chief Superintendent Hayes, of the Borough Police, and the weapon wrenched from his grasp by someone in the crowd. Birmingham Daily Gazette, 1921

Other accounts state that the revolver was a toy and that his aim was disrupted by an Eton schoolboy:

The weapon was a mere toy, and the life of the beloved monarch was not seriously endangered. A number of Eton boys were round the station at the time, and one of them rushed forward and struck Maclean with his umbrella, disconcerting his aim which was unlikely enough, in any case, to have been accurate. The boy in question, Gordon Wilson, was called to the Castle by her Majesty and thanked for his promptitude. He was the son of Sir Samuel Wilson, the Australian wool magnate, who introduced salmon into the Australian rivers and afterwards sat in Parliament for a short time for Portsmouth. Gordon Wilson married Lady Sarah Spencer-Churchill, a sister of Lord Randolph and Lady Wimborne. He was killed in the early days of the war. The wretched lunatic, therefore, survived all the other chief actors in his poor little drama, paying dearly for his brief notoriety. He had, however, the distinction of undergoing trial for high treason. Lichfield Mercury, 1921

At his trial, Dr. Charles Vernon Hitchins testified that MacLean had been certified insane in June 1880, two years before the attempted assassination, and he had been sent to Somerset Lunatic Asylum. He was living at 14 Wadham Street in Weston-super-Mare. Dr. Hitchins stated that Maclean was complaining of headaches and believed that all the people in England are against him, and he felt he must injure someone because they are conspiring to deceive him. He had also sent letters to his sister in 1880, Caroline Maclean, stating that, "If I cannot commit a murder one way, I will another way, and all can add is, if there is more difficulty, there may be more victims." Multiple doctors also testified that Maclean was insane and "did not believe he was capable of appreciating the nature or quality of any act which he might commit."Tried for high treason on 20 April, Maclean was found "not guilty, but insane" by a jury after five minutes' deliberation, overseen by Lord Chief Justice Coleridge. and he lived out his remaining days in Broadmoor Asylum. The verdict prompted the Queen to ask for a change in English law so that those implicated in cases with similar outcomes would be considered as "guilty, but insane"; this led to the Trial of Lunatics Act 1883.A poem was later written about Maclean's attempt on the Queen's life by William Topaz McGonagall.

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.
