Question: When was prime minister first mentioned in a government document in the country Prince of Thieves, whose main character John is depicted alongside, made?

full_context: Document 1: The London Gazette: The London Gazette is one of the official journals of record of the British government, and the most important among such official journals in the United Kingdom, in which certain statutory notices are required to be published. "The London Gazette" claims to be the oldest surviving English newspaper and the oldest continuously published newspaper in the UK, having been first published on 7 November 1665 as The Oxford Gazette. This claim is also made by the "Stamford Mercury" (1712) and "Berrow's Worcester Journal" (1690), because "The Gazette" is not a conventional newspaper offering general news coverage. It does not have a large circulation.
Document 2: John, King of England: Nineteenth-century fictional depictions of John were heavily influenced by Sir Walter Scott's historical romance, Ivanhoe, which presented "an almost totally unfavourable picture" of the king; the work drew on Victorian histories of the period and on Shakespeare's play. Scott's work influenced the late 19th-century children's writer Howard Pyle's book The Merry Adventures of Robin Hood, which in turn established John as the principal villain within the traditional Robin Hood narrative. During the 20th century, John was normally depicted in fictional books and films alongside Robin Hood. Sam De Grasse's role as John in the black-and-white 1922 film version shows John committing numerous atrocities and acts of torture. Claude Rains played John in the 1938 colour version alongside Errol Flynn, starting a trend for films to depict John as an "effeminate ... arrogant and cowardly stay-at-home". The character of John acts either to highlight the virtues of King Richard, or contrasts with the Sheriff of Nottingham, who is usually the "swashbuckling villain" opposing Robin. An extreme version of this trend can be seen in the Disney cartoon version, for example, which depicts John, voiced by Peter Ustinov, as a "cowardly, thumbsucking lion". Popular works that depict John beyond the Robin Hood legends, such as James Goldman's play and later film, The Lion in Winter, set in 1183, commonly present him as an "effete weakling", in this instance contrasted with the more masculine Henry II, or as a tyrant, as in A. A. Milne's poem for children, "King John's Christmas".
Document 3: Prime minister: Canada's constitution, being a 'mixed' or hybrid constitution (a constitution that is partly formally codified and partly uncodified) originally did not make any reference whatsoever to a prime minister, with her or his specific duties and method of appointment instead dictated by "convention". In the Constitution Act, 1982, passing reference to a "Prime Minister of Canada" is added, though only regarding the composition of conferences of federal and provincial first ministers.
Document 4: Journal of the British Astronomical Association: The Journal of the British Astronomical Association is a peer-reviewed scientific journal of astronomy published by the British Astronomical Association since October 1890. It is currently edited by Hazel McGee and publishes original research articles, as well news items relevant to the association and the proceedings of association meetings. Letters to the editor, book reviews, and obituaries are also published.
Document 5: John, King of England: Historical interpretations of John have been subject to considerable change over the years. Medieval chroniclers provided the first contemporary, or near contemporary, histories of John's reign. One group of chroniclers wrote early in John's life, or around the time of his accession, including Richard of Devizes, William of Newburgh, Roger of Hoveden and Ralph de Diceto. These historians were generally unsympathetic to John's behaviour under Richard's rule, but slightly more positive towards the very earliest years of John's reign. Reliable accounts of the middle and later parts of John's reign are more limited, with Gervase of Canterbury and Ralph of Coggeshall writing the main accounts; neither of them were positive about John's performance as king. Much of John's later, negative reputation was established by two chroniclers writing after the king's death, Roger of Wendover and Matthew Paris, the latter claiming that John attempted conversion to Islam in exchange for military aid from the Almohad ruler Muhammad al-Nasir - a story which is considered to be untrue by modern historians.
Document 6: Boys' Brigade Gazette: The Boys' Brigade Gazette is a quarterly magazine printed regularly since 1889 in the United Kingdom for the officers and leaders of the Battalions and Companies of the Boy's Brigade in the UK and Ireland.
Document 7: The Times: This 164-page monthly magazine is sold separately from the newspaper of record and is Britain's best-selling travel magazine. The first issue of The Sunday Times Travel Magazine was in 2003, and it includes news, features and insider guides.
Document 8: The Last of the Mohicans (1992 film): Despite the film taking place in upstate New York, according to the film credits, it was filmed mostly in the Blue Ridge Mountains of North Carolina. Locations used include Lake James, Chimney Rock Park and The Biltmore Estate. Some of the waterfalls that were used in the movie include Hooker Falls, Triple Falls, Bridal Veil Falls, and High Falls, all located in the DuPont State Recreational Forest. Another of these falls was Linville Falls, in the mountains of North Carolina. Scenes of Albany were shot in Asheville, NC at The Manor on Charlotte St.
Document 9: Prime minister: Walpole always denied that he was "prime minister", and throughout the 18th century parliamentarians and legal scholars continued to deny that any such position was known to the Constitution. George II and George III made strenuous efforts to reclaim the personal power of the monarch, but the increasing complexity and expense of government meant that a minister who could command the loyalty of the Commons was increasingly necessary. The long tenure of the wartime prime minister William Pitt the Younger (1783–1801), combined with the mental illness of George III, consolidated the power of the post. The title was first referred to on government documents during the administration of Benjamin Disraeli but did not appear in the formal British Order of precedence until 1905.
Document 10: Robin Hood: Prince of Thieves: Principal exteriors were shot on location in the United Kingdom. A second unit filmed the medieval walls and towers of the Cité de Carcassonne in the town of Carcassonne in Aude, France, for the portrayal of Nottingham and its castle. Locksley Castle was Wardour Castle in Wiltshire -- restored in an early shot using a matte painting. Marian's manor was filmed at Hulne Priory in Northumberland. Scenes set in Sherwood Forest were filmed throughout England: Burnham Beeches in Buckinghamshire was used for the outlaws' encampment, Aysgarth Falls in Yorkshire for the fight scene between Robin and Little John, and Hardraw Force in North Yorkshire was the location where Marian sees Robin bathing. Sycamore Gap on Hadrian's Wall was used for the scene when Robin first confronts the sheriff's men. Chalk cliffs at Seven Sisters, Sussex were used as the locale for Robin's return to England from the Crusades.
Document 11: Prime minister: The United Kingdom's constitution, being uncodified and largely unwritten, makes no mention of a prime minister. Though it had de facto existed for centuries, its first mention in official state documents did not occur until the first decade of the twentieth century. Accordingly, it is often said "not to exist", indeed there are several instances of parliament declaring this to be the case. The prime minister sits in the cabinet solely by virtue of occupying another office, either First Lord of the Treasury (office in commission), or more rarely Chancellor of the Exchequer (the last of whom was Balfour in 1905).
Document 12: Robin Hood: Robin Hood is a heroic outlaw in English folklore who, according to legend, was a highly skilled archer and swordsman. Traditionally depicted dressed in Lincoln green, he is said to rob from the rich and give to the poor. Alongside his band of Merry Men in Sherwood Forest and against the Sheriff of Nottingham, he became a popular folk figure in the Late Middle Ages, and continues to be widely represented in literature, film and television.
Document 13: John, King of England: By the Victorian period in the 19th century historians were more inclined to draw on the judgements of the chroniclers and to focus on John's moral personality. Kate Norgate, for example, argued that John's downfall had been due not to his failure in war or strategy, but due to his "almost superhuman wickedness", whilst James Ramsay blamed John's family background and his cruel personality for his downfall. Historians in the "Whiggish" tradition, focusing on documents such as the Domesday Book and Magna Carta, trace a progressive and universalist course of political and economic development in England over the medieval period. These historians were often inclined to see John's reign, and his signing of Magna Carta in particular, as a positive step in the constitutional development of England, despite the flaws of the king himself. Winston Churchill, for example, argued that "[w]hen the long tally is added, it will be seen that the British nation and the English-speaking world owe far more to the vices of John than to the labours of virtuous sovereigns".
Document 14: Pirates of the Caribbean: On Stranger Tides: Principal photography began on June 14, 2010, in Hawaii. Filming was moved to California in August 2010, primarily at the Long Beach shore and a recreation of Whitecap Bay done in the Universal Studios backlot, as the original Hawaiian location on Halona Cove was plagued with strong tides. After a brief shoot in Puerto Rico, with locations in both Palomino Island and the Fort of San Cristóbal in San Juan, production moved to the United Kingdom in September, where principal photography wrapped on November 18 after 106 days of shooting. Locations included Hampton Court Palace in London, Knole House in Kent, and Old Royal Naval College at Greenwich. Interiors were shot at London's Pinewood Studios, and a replica of an 18th - century London street was built on the backlot alongside the soundstages. The producers also considered using New Orleans as a location. In October, security was breached at the UK site when a celebrity impersonator gained access to filming at the Old Royal Naval College by dressing up as Captain Jack.
Document 15: John, King of England: Contemporary chroniclers were mostly critical of John's performance as king, and his reign has since been the subject of significant debate and periodic revision by historians from the 16th century onwards. Historian Jim Bradbury has summarised the contemporary historical opinion of John's positive qualities, observing that John is today usually considered a "hard-working administrator, an able man, an able general". Nonetheless, modern historians agree that he also had many faults as king, including what historian Ralph Turner describes as "distasteful, even dangerous personality traits", such as pettiness, spitefulness and cruelty. These negative qualities provided extensive material for fiction writers in the Victorian era, and John remains a recurring character within Western popular culture, primarily as a villain in films and stories depicting the Robin Hood legends.
