The Sassoon family built one of the largest fortunes in Asian history on the back of opium addiction. At their peak, they controlled an estimated 70 percent of the opium flowing into China, a trade so vast that historians estimate they supplied enough drug to maintain addiction for roughly 15 percent of China’s entire population. The British called them the Rothschilds of the East. The Chinese had harsher names: drug lords, exploiters, architects of their nation’s century of humiliation.

What makes the story remarkable is its origin. This dynasty did not begin in London boardrooms or colonial offices. It began in flight. Born in Baghdad in 1792, David Sassoon grew up in one of the city’s most influential Jewish families.

His father served as chief treasurer to the Ottoman governors, mediated disputes between the Jewish community and Muslim authorities, and controlled access to Ottoman patronage. The Sassoons were the elite of Baghdad’s Jewish quarter. That position proved fragile. In 1828, political turmoil forced David Sassoon to abandon everything.

He fled Baghdad, initially to Bushire on the Persian Gulf, then onward to Bombay in 1832. He arrived with his wife, eight children, and whatever portable wealth he could smuggle out. Other immigrant merchants quickly adopted British names, dress, and customs. David refused.

He kept his Arabic name, wore traditional robes, and ran an observant Jewish household. This was not merely cultural pride. It was a calculated strategy. Bombay’s economy ran on networks built from trust and shared language, and David could not penetrate the British or Parsi circles.

So he built his own network, a Jewish trading house connecting Baghdad, Calcutta, Bombay, and eventually Canton. The breakthrough came when he identified something the British desperately needed but could not openly manage: opium distribution. The East India Company controlled production in Bengal, but selling the drug in China required merchants who could operate in a contraband economy, navigate Chinese middlemen, handle multiple currencies, and work outside official British channels. China had outlawed the drug, but British gunboats protected the ships that delivered it.

David Sassoon positioned himself precisely inside that contradiction. He became the middleman between British production and Chinese addiction. When the First Opium War erupted in 1839, other merchants fled Canton. The Sassoons waited, maintained their networks, and acquired the contacts of ruined competitors.

By 1842, when Britain forced China to sign the Treaty of Nanking, the Sassoon network stretched from Bombay to Hong Kong. David then made a critical gamble: he sent his second son, Elias, north to Shanghai, then little more than mud flats and fishing villages, with instructions to establish dominance before anyone else understood what the city would become. Between 1843 and 1858, the Sassoons built a vertical monopoly. They negotiated advance contracts with opium growers in Patna and Benares, locking in prices before harvest.

They invested in their own fleet, which grew to 23 vessels by 1850 and 37 by 1880. They placed a son in each major port: Elias in Shanghai, Abdullah in Bombay and Calcutta, Sassoon David in Hong Kong, Solomon in Canton. Blood ties replaced legal contracts. By 1850, the firm moved roughly 4,000 chests of opium annually into China, each weighing about 140 pounds, at profit margins around 400 percent.

Opium bought in India for $300 per chest sold in Shanghai for $1,200 or more. The annual profit from that one commodity alone was $3. 6 million in 1850, roughly $120 million today. The truth was darker still.

Between 1840 and 1858, opium imports to China increased fourfold. The number of addicts grew from roughly 2 million to over 10 million. Silver drained out of the country, regional economies collapsed, and the Qing Dynasty weakened. David kept meticulous records.

A letter from 1851 to Elias in Shanghai noted that British naval patrols had cleared the market of irregular suppliers, allowing the Sassoons to raise prices 23 percent and recommending they maintain volume until local production was suppressed. The British Navy had just destroyed Chinese dealers, creating a shortage the Sassoons exploited. David Sassoon died in 1864, leaving an empire worth roughly $500,000, about $75 million today. His sons divided the business.

It was Elias who turned Shanghai into the family’s greatest achievement. The International Settlement established after the war was a legal vacuum governed by foreigners. Elias bought land in quantity, entire city blocks at a few hundred dollars per acre. When the Taiping Rebellion erupted in 1853, Chinese merchants fled into the foreign concessions for protection, and the Sassoons transformed from opium traders into Shanghai’s landlords.

By 1860, their real estate portfolio was worth more than their opium inventory. The family, however, was tearing itself apart. Abdullah Sassoon, the eldest son, ran the Bombay headquarters and insisted on maintaining the traditional model: keep the opium flowing. Elias agreed, because his expertise lay in distribution networks.

But Abdullah the Younger, educated partly in England, saw the trade as a ticking time bomb. He wanted to reinvest 60 to 70 percent of annual profits into cotton mills, real estate, and banking. His uncles rejected the plan as too risky while opium delivered 400 percent returns. In 1867, Abdullah the Younger split and founded E.

D. Sassoon and Company. The family civil war lasted decades. Cousins competed against each other in Shanghai, driving up prices and allowing the rival trading house Jardine Matheson to gain ground.

By 1875, the Sassoon share of the opium market had fallen from roughly 80 to 65 percent, a loss caused entirely by internal conflict. Paradoxically, both strategies worked. David Sassoon and Sons continued to dominate opium trade into the 1880s. E.

D. Sassoon built cotton mills, acquired Shanghai real estate cheaply, and established banking operations independent of narcotics. The split determined the family’s fate in the twentieth century: the old firm, still dependent on opium, shrank dramatically when the trade collapsed. The diversified firm weathered the transition.

It was a grandson of Abdullah the Younger, Victor Sassoon, who inherited the Shanghai operations and turned the city into a personal empire. Victor was born in 1881 into staggering wealth. A plane crash in World War I left him partially disabled and walking with a cane. He was a playboy capitalist, a racehorse owner who held court at lavish parties and ran the business with ruthless efficiency.

Between 1920 and 1937, Shanghai’s population doubled to 3. 5 million and the city became Asia’s financial capital, the so-called Paris of the East. Victor controlled a massive share of its prime real estate. In 1926, he opened the Cathay Hotel on the Bund, a ten-story Art Deco masterpiece that became the symbol of Shanghai’s glamour.

Charlie Chaplin visited. Noel Coward wrote Private Lives there. Wallis Simpson and Edward VIII allegedly honeymooned in the penthouse. The hotel cost $500,000 to build, roughly $75 million today, and generated enormous returns.

Victor was not merely collecting rent. He manipulated the entire property market. When an American bank wanted to build on the Bund in 1928, Victor quoted three times the market rate. The bank tried to find alternatives, but every prime site was owned by the Sassoons or their associates.

The bank paid. By 1930, borrowing opium profits and accumulated capital, Victor’s Shanghai estate was worth an estimated $3 million, around $450 million today. When Japan invaded Shanghai in 1937, most foreigners fled. Victor stayed.

For four years, the International Settlement remained a neutral enclave surrounded by occupied territory. Wealthy Chinese seeking safety and Jewish refugees fleeing Nazi Europe, for whom Shanghai was one of the few visa-free destinations, poured in. Victor controlled hundreds of apartments and jacked up rents by 200 to 300 percent. He implemented a tiered rental system designed to extract maximum revenue based on each refugee’s remaining wealth.

Desperate families, some with seven people in a former storage closet, paid because the alternative was life under Japanese military rule. When currency collapsed, Victor manufactured arbitrage between yuan, Shanghai dollars, and Japanese military yen, converting worthless paper into real assets. He financed black-market rice and medicine held in Sassoon warehouses, taking 30 to 40 percent of astronomical markups. He paid bribes to Japanese officials and leased properties to the occupation at inflated prices rather than risk confiscation.

In 1940, when a Japanese general demanded the entire Cathay Hotel, Victor negotiated to keep it as a diplomatic neutral zone, reserving a floor for the Japanese military at favorable rates. He kept ownership, collected rent, and made his hotel part of the occupation’s infrastructure. Between 1937 and 1941, Victor privately transferred an estimated $1. 5 million to London banks, nearly $25 million today.

When the communists took Shanghai in 1949, he liquidated the family’s remaining Asian assets, sold the Indian mills and Bombay properties, and exited for good. He died in the Bahamas in 1961. The family scattered and assimilated. Descendants included newspaper editors, art collectors, and a director of the Women’s Royal Naval Service.

Some, like the scholar David Solomon Sassoon, dedicated themselves to preserving Hebrew manuscripts. The Peace Hotel, built by Victor Sassoon, still stands on the Shanghai Bund, where tourists drink tea in rooms paid for by millions of ruined lives. The family’s wealth was absorbed into respectable Western society, and the opium empire slipped into historical obscurity.

The question that remains is how history should judge them: brilliant survivors who mastered the game of empires, or the architects of a nation’s humiliation.
