In the mid 18th century the outcome of a law case gripped the
nation. It led to death threats, riots and the equivalent of £150m
was bet upon its outcome. This was the Douglas Cause.
Archibald, the Duke of Douglas, not been a duke and the owner of
vast swathes of Scotland, history would not have heard of him. He
was virtually illiterate, took no part in the affairs of the nation,
lived as a recluse, died childless and may well have been insane. In
order to ensure the loyalty of the Douglases to the new regime, his dukedom
came from Queen Anne when he was aged nine. His heir was his sister
Jane and, should she fail to produce offspring, the duke’s fortune
and most of his string of ancient titles would pass to his cousin,
married to the Duchess of Hamilton. All looked set fair for the
Hamiltons. Both Jane and her brother were unmarried, at least until
1746 when she made an unsuitable union with Colonel John Stewart, a
Jacobite sympathiser. But that did not seem to be a problem for the
Hamiltons since Jane was 48.
The couple went to the Continent
and, two years later, Jane claimed to have given birth in Paris to
twin boys, Archibald and Sholto.
Encouraged by the Hamiltons,
her brother refused to recognise the boys as her children and his
heirs. He cut off his sister’s allowance and when the couple
returned to Britain in 1751, Stewart was imprisoned for debt. Jane
and her son Sholto both died in 1753 and young Archibald ended up in
the care of the Duke of Queensberry who saw to his education. To
general astonishment Douglas married in 1758. Three years later and
only 10 days before he died his duchess managed to persuade him to
accept Archibald as his heir.
Archibald changed his name from
Stewart to Douglas and, after a brief legal tussle with the
Hamiltons, he duly entered into his inheritance, then worth the
remarkable sum of £12,000 a year.
With so much at stake, it
was unsurprising that the Hamiltons objected. They sent a 'shady
investigator' to Paris who came back with the information that
Archibald was actually Jacques Louis Mignon, son of a glassworker,
who had been kidnapped in July 1748 by ‘a Lady, a Gentleman and
their maid’, that Sholto was the son of Sanry the Rope Dancer who
had vanished in similar circumstances. The 'gumshoe' (1) also reported
that the whole story of Jane’s pregnancy was a fraud, that witnesses
to it could not be found, that the couple had not stayed where they
said they had.
In 1762, the Hamiltons launched an action in
the Court of Session in Edinburgh claiming that Archibald was no
Douglas and had no right to the inheritance and that it was absurd
to claim that Jane could have had twins at 51. By 1767, at the
request of the judges, each side had published memorials - 1,000
page statements of their cases, containing letters, documents,
witness reports, affidavits, citations of Scots and French law and
anything else that the lawyers could think of. For the legal
profession the case was a bonanza, lasting eight years and racking
up costs of £52,000 before it was resolved. Litigation took place in
Scotland, England and France with immense public interest throughout
Europe being taken in every stage of the process.
had an opinion and everyone took sides. David Hume, Adam Smith and
Dr Samuel Johnson all supported the Hamiltons. Johnson’s biographer,
James Boswell, disagreed and became a propagandist for Archibald’s
faction, producing more than 20 articles and three books on the
subject. He had the Edinburgh mob on his side.
interest, a total of 24 lawyers read speeches to the 15 judges
before whom the case was heard. The speechifying lasted 21 days,
making it the longest ever pleading before the Court of Session. On
14th July 1767, the Court gave its opinion. The judges were split
down the middle, seven in favour of the Hamiltons and seven for
|Archibald, 1st Lord Douglas
The Lord President, Robert Dundas, gave a casting
vote in favour of Hamilton. As one contemporary observer, lawyer
Robert Stewart wrote ‘poor Douglas lost his cause yesterday by the
president’s casting vote, leaving him without father or mother,
sister or brother or any relation on Earth for the evidence on which
he is condemned does not give him in law other parents’.
Archibald’s lawyers immediately launched an appeal to the House of
Lords in London. Apart from anything else £100,000’s worth of bets
depended on the outcome, perhaps £150 million in today’s money. The
case opened in January 1769 and lasted over a month. During its
hearing, the private detective challenged and fought a duel against
one of Archibald’s lawyers who had called him a liar. Pistols were
fired but both missed. The decision was unanimously reversed and
Edinburgh went wild with joy.
The judges who had opposed
Douglas had their windows smashed and the mob plundered the Hamilton
apartments in Holyrood House. For two days it was dangerous for
opponents of Archibald to be in Edinburgh. Then troops were ordered
to the city and order was restored.
The dukedom died with
Archibald’s uncle but the young man became one of the richest
magnates in Scotland, owning land in Wiltshire as well as eight
counties north of the border.
He was an improving landlord,
married twice into ducal families and entered politics as MP for
Forfarshire. In 1782 was raised to the peerage as Baron Douglas of
Douglas in 1790. After an unexceptional life he died in 1827 aged
In a corollary to the story, in 2008 letters were found
in the archives of the Earl of Home written by Archibald’s mother
Jane and one of her lawyers. They strongly indicate that she and her
husband did actually buy the babies in Paris.
1. The 'gumshoe' was Andrew Stuart of Castlemilk and
Torrance. He was engaged by James, sixth duke of Hamilton, as tutor
to his children, and through his influence was in 1770 appointed
Keeper of the Signet of Scotland. When the famous Douglas lawsuit
arose, in which the Duke of Hamilton disputed the identity of
Archibald James Edward Douglas, first baron Douglas, and endeavoured
to hinder his succession to the family estates, Stuart was engaged
to conduct the case against the claimant. In the course of the suit,
which was finally decided in the House of Lords in February 1769 in
favour of Douglas, he distinguished himself highly, but so much
feeling arose between him and Edward Thurlow (afterwards Lord
Thurlow), the opposing counsel, that a duel took place. After the
decision of the case Stuart in 1773 published a series of Letters to
Lord Mansfield (London, 4to), who had been a judge in the case, and
who had very strongly supported the claims of Douglas. In these
epistles he assailed Mansfield for his want of impartiality with a
force and eloquence that caused him at the time to be regarded as a
worthy rival to Junius.
