Question: What year did the person who issued the Royal Proclamation of 1763 die?

full_context: Document 1: Queen Victoria: At the time of her accession, the government was led by the Whig prime minister Lord Melbourne, who at once became a powerful influence on the politically inexperienced Queen, who relied on him for advice. Charles Greville supposed that the widowed and childless Melbourne was "passionately fond of her as he might be of his daughter if he had one", and Victoria probably saw him as a father figure. Her coronation took place on 28 June 1838 at Westminster Abbey. Over 400,000 visitors came to London for the celebrations. She became the first sovereign to take up residence at Buckingham Palace and inherited the revenues of the duchies of Lancaster and Cornwall as well as being granted a civil list allowance of £385,000 per year. Financially prudent, she paid off her father's debts.
Document 2: French and Indian War: Britain gained control of French Canada and Acadia, colonies containing approximately 80,000 primarily French-speaking Roman Catholic residents. The deportation of Acadians beginning in 1755 resulted in land made available to migrants from Europe and the colonies further south. The British resettled many Acadians throughout its North American provinces, but many went to France, and some went to New Orleans, which they had expected to remain French. Some were sent to colonize places as diverse as French Guiana and the Falkland Islands; these latter efforts were unsuccessful. Others migrated to places like Saint-Domingue, and fled to New Orleans after the Haitian Revolution. The Louisiana population contributed to the founding of the modern Cajun population. (The French word "Acadien" evolved to "Cadien", then to "Cajun".)
Document 3: Queen Victoria: At birth, Victoria was fifth in the line of succession after her father and his three older brothers: the Prince Regent, the Duke of York, and the Duke of Clarence (later William IV). The Prince Regent and the Duke of York were estranged from their wives, who were both past child-bearing age, so the two eldest brothers were unlikely to have any further children. The Dukes of Kent and Clarence married on the same day 12 months before Victoria's birth, but both of Clarence's daughters (born in 1819 and 1820 respectively) died as infants. Victoria's grandfather and father died in 1820, within a week of each other, and the Duke of York died in 1827. On the death of her uncle George IV in 1830, Victoria became heiress presumptive to her next surviving uncle, William IV. The Regency Act 1830 made special provision for the Duchess of Kent to act as regent in case William died while Victoria was still a minor. King William distrusted the Duchess's capacity to be regent, and in 1836 declared in her presence that he wanted to live until Victoria's 18th birthday, so that a regency could be avoided.
Document 4: Northern Seven Years' War: The British government was close to bankruptcy, and Britain now faced the delicate task of pacifying its new French-Canadian subjects as well as the many American Indian tribes who had supported France. George III's Proclamation of 1763, which forbade white settlement beyond the crest of the Appalachians, was intended to appease the latter but led to considerable outrage in the Thirteen Colonies, whose inhabitants were eager to acquire native lands. The Quebec Act of 1774, similarly intended to win over the loyalty of French Canadians, also spurred resentment among American colonists. The act protected Catholic religion and French language, which enraged the Americans, but the Québécois remained loyal and did not rebel.
Document 5: French and Indian War: In between the French and the British, large areas were dominated by native tribes. To the north, the Mi'kmaq and the Abenaki were engaged in Father Le Loutre's War and still held sway in parts of Nova Scotia, Acadia, and the eastern portions of the province of Canada, as well as much of present-day Maine. The Iroquois Confederation dominated much of present-day Upstate New York and the Ohio Country, although the latter also included Algonquian-speaking populations of Delaware and Shawnee, as well as Iroquoian-speaking Mingo. These tribes were formally under Iroquois rule, and were limited by them in authority to make agreements.
Document 6: French and Indian War: Following the treaty, King George III issued the Royal Proclamation of 1763 on October 7, 1763, which outlined the division and administration of the newly conquered territory, and to some extent continues to govern relations between the government of modern Canada and the First Nations. Included in its provisions was the reservation of lands west of the Appalachian Mountains to its Indian population, a demarcation that was at best a temporary impediment to a rising tide of westward-bound settlers. The proclamation also contained provisions that prevented civic participation by the Roman Catholic Canadians. When accommodations were made in the Quebec Act in 1774 to address this and other issues, religious concerns were raised in the largely Protestant Thirteen Colonies over the advance of "popery"; the Act maintained French Civil law, including the seigneurial system, a medieval code soon to be removed from France within a generation by the French Revolution.
Document 7: Queen Victoria: Victoria's father was Prince Edward, Duke of Kent and Strathearn, the fourth son of the reigning King of the United Kingdom, George III. Until 1817, Edward's niece, Princess Charlotte of Wales, was the only legitimate grandchild of George III. Her death in 1817 precipitated a succession crisis that brought pressure on the Duke of Kent and his unmarried brothers to marry and have children. In 1818 he married Princess Victoria of Saxe-Coburg-Saalfeld, a widowed German princess with two children—Carl (1804–1856) and Feodora (1807–1872)—by her first marriage to the Prince of Leiningen. Her brother Leopold was Princess Charlotte's widower. The Duke and Duchess of Kent's only child, Victoria, was born at 4.15 a.m. on 24 May 1819 at Kensington Palace in London.
Document 8: Queen Victoria: During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother. Oxford fired twice, but either both bullets missed or, as he later claimed, the guns had no shot. He was tried for high treason and found guilty, but was acquitted on the grounds of insanity. In the immediate aftermath of the attack, Victoria's popularity soared, mitigating residual discontent over the Hastings affair and the bedchamber crisis. Her daughter, also named Victoria, was born on 21 November 1840. The Queen hated being pregnant, viewed breast-feeding with disgust, and thought newborn babies were ugly. Nevertheless, over the following seventeen years, she and Albert had a further eight children: Albert Edward, Prince of Wales (b. 1841), Alice (b. 1843), Alfred (b. 1844), Helena (b. 1846), Louise (b. 1848), Arthur (b. 1850), Leopold (b. 1853) and Beatrice (b. 1857).
Document 9: Royal Proclamation of 1763: The Royal Proclamation of 1763 was issued October 7, 1763, by King George III following Great Britain's acquisition of French territory in North America after the end of the French and Indian War / Seven Years' War. It forbade all settlement west of a line drawn along the Appalachian Mountains, which was delineated as an Indian Reserve.
Document 10: Queen Victoria: Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn, the fourth son of King George III. Both the Duke of Kent and King George III died in 1820, and Victoria was raised under close supervision by her German-born mother Princess Victoria of Saxe-Coburg-Saalfeld. She inherited the throne aged 18, after her father's three elder brothers had all died, leaving no surviving legitimate children. The United Kingdom was already an established constitutional monarchy, in which the sovereign held relatively little direct political power. Privately, Victoria attempted to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.
Document 11: Royal Proclamation of 1763: In the United States, the Royal Proclamation of 1763 ended with the American Revolutionary War because Great Britain ceded the land in question to the United States in the Treaty of Paris (1783). Afterward, the U.S. government also faced difficulties in preventing frontier violence and eventually adopted policies similar to those of the Royal Proclamation. The first in a series of Indian Intercourse Acts was passed in 1790, prohibiting unregulated trade and travel in Native American lands. In 1823, the U.S. Supreme Court case Johnson v. M'Intosh established that only the U.S. government, and not private individuals, could purchase land from Native Americans.
Document 12: Queen Victoria: In 1830, the Duchess of Kent and Conroy took Victoria across the centre of England to visit the Malvern Hills, stopping at towns and great country houses along the way. Similar journeys to other parts of England and Wales were taken in 1832, 1833, 1834 and 1835. To the King's annoyance, Victoria was enthusiastically welcomed in each of the stops. William compared the journeys to royal progresses and was concerned that they portrayed Victoria as his rival rather than his heiress presumptive. Victoria disliked the trips; the constant round of public appearances made her tired and ill, and there was little time for her to rest. She objected on the grounds of the King's disapproval, but her mother dismissed his complaints as motivated by jealousy, and forced Victoria to continue the tours. At Ramsgate in October 1835, Victoria contracted a severe fever, which Conroy initially dismissed as a childish pretence. While Victoria was ill, Conroy and the Duchess unsuccessfully badgered her to make Conroy her private secretary. As a teenager, Victoria resisted persistent attempts by her mother and Conroy to appoint him to her staff. Once queen, she banned him from her presence, but he remained in her mother's household.
Document 13: Huguenots: The exodus of Huguenots from France created a brain drain, as many Huguenots had occupied important places in society. The kingdom did not fully recover for years. The French crown's refusal to allow non-Catholics to settle in New France may help to explain that colony's slow rate of population growth compared to that of the neighbouring British colonies, which opened settlement to religious dissenters. By the time of the French and Indian War (the North American front of the Seven Years' War), a sizeable population of Huguenot descent lived in the British colonies, and many participated in the British defeat of New France in 1759-60.
Document 14: History of Canada: With the end of the Seven Years' War and the signing of the Treaty of Paris (1763), France ceded almost all of its remaining territory in mainland North America, except for fishing rights off Newfoundland and the two small islands of Saint Pierre and Miquelon where its fishermen could dry their fish. France had already secretly ceded its vast Louisiana territory to Spain under the Treaty of Fontainebleau (1762) in which King Louis XV of France had given his cousin King Charles III of Spain the entire area of the drainage basin of the Mississippi River from the Great Lakes to the Gulf of Mexico and from the Appalachian Mountains to the Rocky Mountains. France and Spain kept the Treaty of Fontainebleau secret from other countries until 1764. In return for acquiring Canada, Britain returned to France its most important sugar - producing colony, Guadeloupe, which the French at the time considered more valuable than Canada. (Guadeloupe produced more sugar than all the British islands combined, and Voltaire had notoriously dismissed Canada as ``Quelques arpents de neige '',`` A few acres of snow'').
Document 15: Queen Victoria: Though queen, as an unmarried young woman Victoria was required by social convention to live with her mother, despite their differences over the Kensington System and her mother's continued reliance on Conroy. Her mother was consigned to a remote apartment in Buckingham Palace, and Victoria often refused to see her. When Victoria complained to Melbourne that her mother's close proximity promised "torment for many years", Melbourne sympathised but said it could be avoided by marriage, which Victoria called a "schocking  [sic] alternative". She showed interest in Albert's education for the future role he would have to play as her husband, but she resisted attempts to rush her into wedlock.
