Scottish financier who ran France's finances from 1716 to 1720, launching paper money and a share boom that ended in a famous crash.

A gambler who fled Britain after killing a man in a 1694 duel, Law argued that paper money would spur trade. Backed by the regent Philippe d'Orléans, he opened a bank in 1716 and took over the Mississippi Company, which swapped France's war debts for shares. Shares rose from about 500 to 10,000 livres in 1719, and the word 'millionaire' spread. Law became finance minister in 1720; shares and notes then collapsed, and he died poor in Venice in 1729.
Impact on society and the economy
Briefly among Europe's richest men, he eased France's debt burden but ruined late investors and left the French wary of banks and paper money for generations. New Orleans, founded under his company in 1718, endures.
Fortune, legacy and how we know
His own writings, notably Money and Trade Considered (1705), French royal decrees, share prices from the Rue Quincampoix market, and contemporary prints and letters mocking the crash.
Still debated
Economists still debate whether his system was a fraud or a sound idea wrecked by overissue; some see him as an early theorist of modern central banking.

▸Paper money in Song China foreshadowed the paper-money experiment of John Law and the Mississippi BubbleMostly agreed
The connection
Song China proved paper notes could work as money when people trusted the issuer; later Yuan and Ming overprinting showed how fast that trust collapses. Nearly seven centuries later, Law argued paper backed by land and company shares could revive France's trade. His notes followed the same arc, booming in 1719 and collapsing in 1720 after he printed too many.
When and how
Sichuan, China, from 1024; Europe heard of Chinese paper money through Marco Polo around 1300; Paris, 1716–1720.
How sure are we?
The parallel is clear, but direct influence is not documented: Law's writings drew mainly on Dutch and English banking, and Europe already had banknotes, as in Stockholm in 1661.
Debates
Whether Chinese practice influenced European paper money at all, through travelers' reports, is unproven; the two experiments mostly show the same lesson learned twice.
▸John Law and the Mississippi Bubble ran the French twin of South Sea Company and its bubbleWell documented
The connection
Law's Mississippi Company swapped French government debt for soaring shares in 1719. British ministers feared France would shed its debts and gain an edge, and the South Sea Company copied the debt-for-equity swap in 1720. Money and speculators moved between Paris and London; Law's system cracked first, and the South Sea boom collapsed months later.
When and how
Paris and London, 1719–1720; John Law, the regent Philippe d'Orléans, South Sea director John Blunt, and British ministers.
How we know
Contemporaries compared the schemes directly, and price records show the Paris peak around January 1720, followed by London's in June.
Debates
Whether capital flowing from Paris fueled the London boom, as historian Larry Neal and others discuss, and how directly Blunt copied Law are debated.
