Gregor MacGregor (24 December 1786 – 4 December 1845) was a Scottish soldier, adventurer and con man who attempted from 1821 to 1837 to draw British and French investors and settlers to "Poyais", a fictional Central American territory that he claimed to rule as "Cazique". Hundreds invested their savings in supposed Poyaisian government bonds and land certificates. About 250 emigrated to MacGregor's invented country in 1822–1823 to find only an untouched jungle in Honduras; more than half of them died. MacGregor's Poyais scheme has been called one of the most brazen confidence tricks in history.
From the Clan Gregor, MacGregor was commissioned into the British Army in 1803 and participated in the Peninsular War before being discharged in 1810. He joined the republican side in the Venezuelan War of Independence in 1812, quickly became a general and, over the next four years, operated against the Spanish on behalf of both Venezuela and its neighbour New Granada. His successes included a difficult month-long fighting retreat through northern Venezuela in 1816. He captured Amelia Island in 1817 under a mandate from revolutionary agents to conquer Spanish Florida, and there proclaimed a short-lived "Republic of the Floridas". He then oversaw two calamitous operations in New Granada during 1819 that each ended with him abandoning the British volunteer troops under his command.
On his return to Britain in 1821, MacGregor claimed that King George Frederic Augustus of the Mosquito Coast in the Gulf of Honduras had appointed him Cazique of Poyais, which he described as a developed colony with a community of British settlers. When the British press reported on MacGregor's deception following the return of fewer than 50 survivors in late 1823, some of his victims leaped to his defence, insisting that the general had been let down by those whom he had put in charge of the emigration party. A French court tried MacGregor and three others for fraud in 1826 after he attempted a variation on the scheme there, but convicted only one of his associates. Acquitted, MacGregor attempted lesser Poyais schemes in London over the next decade. In 1838, he moved to Venezuela, where he was welcomed back as a hero. He died in Caracas in 1845, aged 58, and was buried with full military honours in Caracas Cathedral.
Gregor MacGregor was born on Christmas Eve 1786 at his family's ancestral home of Glengyle, on the north shore of Loch Katrine in Stirlingshire, Scotland. He was the son of Daniel MacGregor, an East India Company sea captain, and his wife Ann (née Austin). The family was Roman Catholic and part of the Clan Gregor, whose proscription by King James VI and I in 1604 had been repealed only in 1774. During the proscription, the MacGregors had been legally ostracised to the extent that they were forbidden to use their own surname—many of them, including Gregor's great-great-uncle Rob Roy, had participated in the Jacobite risings of 1715 and 1745. MacGregor would assert in adulthood that a direct ancestor of his had survived the Darien scheme of 1698, the ill-fated Scottish attempt to colonise the Isthmus of Panama. Gregor's grandfather, also called Gregor and nicknamed "the Beautiful", served with distinction in the British Army under the surname Drummond, and subsequently played an important role in the clan's restoration and rehabilitation into society.
Little is recorded of MacGregor's childhood. After his father's death in 1794, he and his two sisters were raised primarily by his mother with the help of various relatives. MacGregor's biographer David Sinclair speculates that he would probably have spoken mainly Gaelic during his early childhood, and learned English only after starting school around the age of five-and-a-half. MacGregor would claim in later life to have studied at the University of Edinburgh between 1802 and 1803; records of this do not survive as he did not take a degree, but Sinclair considers it plausible, citing MacGregor's apparent sophistication and his mother's connections in Edinburgh.
MacGregor joined the British Army at 16, the youngest age it was possible for him to do so, in April 1803. His family purchased him a commission as an ensign in the 57th (West Middlesex) Regiment of Foot, probably for around £450. MacGregor's entrance to the military coincided with the start of the Napoleonic Wars following the breakdown of the Treaty of Amiens. Southern England was fortified to defend against a possible French invasion; the 57th Foot was at Ashford, Kent. In February 1804, after less than a year in training, MacGregor was promoted without purchase to lieutenant—an advancement that usually took up to three years. Later that year, after MacGregor had spent some months in Guernsey with the regiment's 1st Battalion, the 57th Foot was posted to Gibraltar.
MacGregor was introduced to Maria Bowater, the daughter of a Royal Navy admiral, around 1804. Maria commanded a substantial dowry and, apart from her by-now-deceased father, was related to two generals, a member of parliament and the botanist Aylmer Bourke Lambert. Gregor and Maria married at St Margaret's, Westminster in June 1805 and set up home in London, at the residence of the bride's aunt. Two months later, having rejoined the 57th Foot in Gibraltar, MacGregor bought the rank of captain for about £900, choosing not to wait the seven years such a promotion might take without purchase. The 57th Foot remained in Gibraltar between 1805 and 1809. During this time, MacGregor developed an obsession with dress, rank insignia and medals that made him unpopular in the regiment; he forbade any enlisted man or non-commissioned officer from leaving their quarters without wearing the full dress uniform.
In 1809 the 57th Foot was sent to Portugal as reinforcements for the Anglo-Portuguese Army under the Duke of Wellington, during his second attempt to drive the French out of Spain during the Peninsular War. MacGregor's regiment disembarked at Lisbon about three months into the campaign, on 15 July. By September it was garrisoning Elvas, near the frontier with Spain. Soon thereafter MacGregor was seconded to the 8th Line Battalion of the Portuguese Army, where he served with the rank of major from October 1809 to April 1810. According to Michael Rafter, author of a highly critical 1820 biography of MacGregor, this secondment came after a disagreement between MacGregor and a superior officer, "originally of a trivial nature", that intensified to such an extent that the young captain was forced to request discharge. This was promptly granted. MacGregor formally retired from the British service on 24 May 1810, receiving back the £1,350 he had paid for the ranks of ensign and captain, and returned to Britain. The 57th Foot's actions at the Battle of Albuera on 16 May 1811 would earn it considerable prestige and the nickname "the Die-Hards"; MacGregor would thereafter make much of his association—despite having left the regiment one year prior.
On his return to Britain the 23-year-old MacGregor and his wife moved into a house rented by his mother in Edinburgh. There he assumed the title of "Colonel", wore the badge of a Portuguese knightly order and toured the city in an extravagant and brightly coloured coach. After failing to attain high social status in Edinburgh, MacGregor moved back to London in 1811 and began styling himself "Sir Gregor MacGregor, Bart.", falsely claiming to have succeeded to the MacGregor clan chieftainship; he also alluded to family ties with a selection of dukes, earls and barons. This had little bearing on reality but MacGregor nevertheless created an air of credible respectability for himself in London society.
In December 1811, Maria MacGregor died. At a stroke MacGregor lost his main source of income and the support of the influential Bowater family. His options were, Sinclair suggests, limited: announcing his engagement to another heiress so soon after Maria's death might draw embarrassing public protests from the Bowaters, and returning home to farm the MacGregor lands in Scotland would be in his mind unacceptably dull. His only real experience was military, but the manner of his exit from the British Army would make a return there awkward at best.
