Money and trade considered, with a proposal for supplying the Nation with money', 1934
Law was born into a family of bankers and
Fife; his father, William, had purchased
Lauriston Castle, a landed estate at
Cramond on the
Firth of Forth and was known as Law of
Lauriston. Law joined the family business at age fourteen and studied the banking business until his father died in 1688. Law subsequently neglected the firm in favour of more extravagant pursuits and travelled to London to live the British
dandy lifestyle. He subsequently lost large sums of money in gambling.
On 9 April 1694, John Law fought a
duel with another British dandy, Edward "Beau" Wilson, in
Bloomsbury Square, London.
 Wilson had challenged Law over the affections of
Elizabeth Villiers. Law killed Wilson with a single pass and thrust of his sword.
 He was arrested, charged with murder and stood trial at the
 He appeared before the infamously sadistic 'hanging-judge',
Salathiel Lovell and was found guilty of murder, and sentenced to death.
 He was initially incarcerated in
Newgate Prison to await execution.
 His sentence was later commuted to a fine, upon the ground that the offence only amounted to
manslaughter. Wilson's brother appealed and had Law imprisoned, but he managed to escape to

Law urged the establishment of a
national bank to create and increase instruments of
credit and the issue of
banknotes backed by land, gold, or silver. The first manifestation of Law's system came when he had returned to Scotland and contributed to the debates leading to the
Treaty of Union 1707. He published a text entitled
Money and Trade Considered: with a Proposal for Supplying the Nation with Money (1705).
:136 Law's propositions of creating a national bank in
Scotland were ultimately rejected, and he left to pursue his ambitions abroad.
He spent ten years moving between France and the
Netherlands, dealing in financial
speculations. Problems with the French economy presented the opportunity to put his system into practice.
He had the idea of abolishing minor
monopolies and private
farming of taxes. He would create a bank for national finance and a state company for commerce, ultimately to exclude all private revenue. This would create a huge monopoly of finance and trade run by the state, and its profits would pay off the
national debt. The council called to consider Law's proposal, including financiers such as
Samuel Bernard, rejected the proposition on 24 October 1715.
Law made his home in Place Louis-le-Grand, a royal square where he hosted and entertained various Parisian nobles. Gaining the attention of such notable people as the Duke of Orleans, Law quickly found himself a regular in high-stakes gambling parties attended by only the most affluent of Paris. His tall stature and elegant dress allowed Law to charm his way across Europe's financial hubs, from Amsterdam to Venice. These travels heavily influenced Law's theories on monetary policy and the importance of paper money as credit. Law's idea of a centralised bank which would deal in a new form of paper money was years ahead of its time. Despite this forward concept, Law still championed mercantilist beliefs with the promotion of monopolistic companies through government charters.
The wars waged by
Louis XIV left the country completely wasted, both economically and financially. The resultant shortage of
precious metals led to a shortage of coins in circulation, which in turn limited the production of new coins. With the death of Louis XIV seventeen months after Law's arrival, the Duke of Orleans finally presented Law with the opportunity to showcase his ingenuity. Since, following the devastating
War of the Spanish Succession, France's economy was stagnant and her
national debt was crippling, Law proposed to stimulate industry by replacing gold with paper credit and then increasing the supply of credit, and to reduce the national debt by replacing it with shares in economic ventures.
 On 1 May 1716, Law presented a modified version of his centralised bank plan to the Banque Generale which approved a private bank that allowed investors to supply one-fourth of an investment in currency and the other parts in defunct government bonds. The second key feature of the proposal centred on the premise that this private bank was able to issue its own currency backed by
Louis of gold. This enabled the currency to be redeemed by the weight of silver from the original deposit instead of the fluctuating value of the
livres which had been devaluing rapidly.
In May 1716 Law set up the Banque Générale Privée ("General Private Bank"), which developed the use of paper money.
 It was one of only six such banks to have issued paper money, joining Sweden, England, Holland, Venice, and Genoa.
 The bank was nationalised in December 1718 at Law's request.
From this new banking platform, Law was able to pursue the
monopoly companies he envisioned by having France bankroll the endeavour with 100 million livres in the form of company stock. The founding of the Mississippi Company, later renamed the Occident Company and eventually part of the Company of the Indies, was financed in the same way as the bank.
In this context the regent,
Philippe d'Orléans, appointed Law as Controller General of Finances in 1720, effectively giving him control over external and internal commerce. The rapid ascension of this new global monopoly led to massive speculation and stock prices ballooned to over sixty times their original value.
As Controller General, Law instituted many beneficial reforms (some of which had lasting effect, while others were soon abolished). He tried to break up large land-holdings to benefit the peasants; he abolished internal road and canal tolls; he encouraged the building of new roads, the starting of new industries (even importing artisans but mostly by offering low-interest loans), and the revival of overseas commerce—and indeed industry increased 60% in two years, and the number of French ships engaged in export went from sixteen to three hundred.
Company of the West
Law became the architect of what would later be known as
The Mississippi Bubble, an event that would begin with consolidating the trading companies of
Louisiana into a single monopoly (The Mississippi Company), and ended with the collapse of the
Banque Générale and subsequent devaluing of the Mississippi Company's shares.
In 1719, the French government allowed Law to issue 50,000 new shares in the Mississippi Company at 500 livres with just 75 livres down and the rest due in nineteen additional monthly payments of 25 livres each. The share price rose to 1,000 livres before the second instalment was even due, and ordinary citizens flocked to Paris to participate.
In October 1719 Law's Company lent the French state 1.5 billion livres at 3% to pay off the national debt, a transaction funded by issuing a further 300,000 shares in the company.
Between May and December 1719 the market price of a share rose from 500 to 10,000 livres
:277 and continued rising into early 1720, supported by Law's 4% dividend promise.
:143–4 Under rapidly emerging price inflation,
 Law sought to hold the share price at 9,000 livres in March 1720, and then on 21 May 1720 to engineer a controlled reduction in the value of both notes and the shares, a measure that was itself reversed 6 days later.
As the public rushed to convert banknotes to coin, Law was forced to close the Banque Générale for ten days, then limit the transaction size once the bank reopened. But the queues grew longer, the Mississippi Company stock price continued to fall, and food prices soared by as much as 60 percent.
The fractional reserve ratio was one fifth,
 and a Royal edict to criminalise the sale of gold was decreed.
 A later Royal edict decreed that gold coin was illegal,
 which was soon reversed,
 leading 50 people to be stampeded to death.
 The company's shares were ultimately rendered worthless, and initially inflated speculation about their worth led to widespread financial stress, which saw Law dismissed at the end of 1720 from his sinecure as Controller General
 and his post as Chief Director of the Banque Générale.
Speculation gave way to panic as people flooded the market with future shares trading as high as fifteen thousand livres per share, while the shares themselves maintained at ten thousand livres each. By May 1720, prices fell to 4,000 livres per share, a 73% decrease within a year. The rush to convert paper money to coins led to sporadic bank hours and riots. Squatters now occupied the square of Palace Louis-le-Grand and openly attacked the financiers that inhabited the area. It was under these circumstances and the cover of night that John Law fled Paris some seven months later.
The descent of a relatively unknown man came as fast as his rise, leaving an economic power vacuum. Law's theories live on 300 years later and "captured many key conceptual points which are very much a part of modern monetary theorizing".

Law initially moved to
Brussels on 22 December 1720 in impoverished circumstances as his properties in France were confiscated.
:148 He spent the next few years gambling in Rome,
Venice but never regained his former prosperity. Law realised he would never return to France when Orléans died suddenly in 1723 and Law was granted permission to return to London, having received a pardon in 1719. He lived in London for four years and then moved to Venice where he contracted
pneumonia and died a poor man in 1729.
