A man walks into a waterfront bar in San Francisco, orders a drink, and wakes up three days later in the Pacific Ocean. He has no memory of signing anything. He has no idea how he got aboard this ship. What he does know is that the captain considers him a sailor now, and the vessel won't touch land for months. This was not a rare occurrence in 19th-century port cities. It was an industry.
The men who orchestrated these kidnappings were called crimps, and their victims numbered in the thousands. The practice acquired a name that entered the English language permanently: shanghaiing, after the Chinese port city that symbolized the most distant and dreaded destinations. What the familiar version of this history often overlooks is that shanghaiing wasn't simply random violence by waterfront thugs. It was an organized labor market—one where ship captains, boarding house keepers, and municipal authorities operated in tacit collaboration, and where the commodity being traded was human beings who had committed no crime.
Why Did Ship Captains Pay for Unconscious Men?
The answer lies in the brutal economics of 19th-century maritime labor. Sailing ships required large crews for operations that were dangerous, exhausting, and poorly paid. Voyages lasted months or years. Desertion rates were catastrophic—sailors fled at every port where opportunities on land seemed preferable to another journey around Cape Horn. When a ship needed to depart and lacked sufficient crew, the captain faced financial ruin. Cargo contracts had deadlines. Investors demanded returns. And the legal framework of the era treated sailors as quasi-property once they had signed articles of agreement.
This desperation created demand. Crimps supplied it. They operated boarding houses where sailors stayed between voyages, extending credit for food, drink, and lodging that accumulated into debts the sailors could never repay except by shipping out again—with the crimp collecting a fee from the captain. When willing sailors weren't available, crimps found unwilling ones. The standard payment from a captain to a crimp was called "blood money," typically ranging from thirty to one hundred dollars per body delivered. At those prices, a productive crimp could earn more than most legitimate businessmen in the city.
The Boarding House System That Enabled Mass Kidnapping
Crimping required infrastructure. The most notorious crimps ran establishments that served multiple functions simultaneously: they were bars, hotels, employment offices, and holding cells. James Kelly, known as "Shanghai" Kelly, operated out of San Francisco and became legendary for his ability to supply crews to understaffed vessels. His boarding house, variously reported on Pacific or Broadway streets, served as the nerve center of his operations. He also ran multiple bars—establishments where the drinks came with extras.
The drugs used varied, but the most common was laudanum, an opium tincture that was legal, cheap, and easy to administer without detection. A sufficient dose in a man's whiskey produced hours of unconsciousness. Chloral hydrate, which would later become known as "knockout drops" or a component of a "Mickey Finn," also saw use. The victim would be carried through tunnels or back doors, transported to a waiting ship, and presented to the captain as a sailor who had signed articles while drunk and was now sleeping it off. By the time he regained consciousness, the ship was at sea.
Joseph "Bunko" Kelly claimed to have shanghaied approximately 2,000 men and women during his 15-year career beginning in 1879—a figure that, if accurate, represents an industrial-scale kidnapping operation operating in plain sight.
Kelly, who operated primarily in Portland, Oregon, earned his nickname "Bunko" for his skill at confidence tricks. His methods went beyond simple drugging. Trickery, intimidation, and outright violence all featured in his repertoire. The fact that he operated for fifteen years without significant legal consequence tells us something important about the institutional environment that made shanghaiing possible.
How Did Crimps Operate Without Prosecution?
The legal and political landscape of 19th-century port cities was not designed to protect transient workers. Sailors had few advocates. They were often foreign nationals with no political voice. They moved constantly and left no permanent addresses. They had reputations—often unfair—for drunkenness and unreliability that made authorities skeptical of their complaints. And critically, the shipping industry generated enormous economic value for port cities. Politicians and police had strong incentives to ensure that ships departed on schedule, fully crewed.
The result was a system of calculated blindness. Crimps paid bribes. Ship captains maintained plausible deniability about how their crews were assembled. When a shanghaied man reached his home port again—if he ever did—months or years had passed, witnesses had scattered, and pressing charges was practically impossible. The burden of proof fell entirely on the victim, who usually had no documentation of what had happened and whose word was weighed against that of established businessmen.
The vocabulary itself reveals the normalization. "Crimping" became a recognized occupation. The payments captains made were called "blood money" openly, without apparent shame. These were not secret activities conducted in whispers. They were systematic, understood, and tolerated because they solved a problem that the legitimate economy couldn't solve through legitimate means.
The Gradual Collapse of the Trade
Several factors combined to end the era of shanghaiing. Steam power reduced crew sizes dramatically—a steamship needed far fewer hands than a sailing vessel of comparable tonnage. Labor reforms in the late 19th and early 20th centuries strengthened sailors' legal protections. The Seamen's Act of 1915 in the United States finally abolished the imprisonment of sailors for desertion and established that they had to sign articles in the presence of a shipping commissioner, making the old system of forged or coerced signatures more difficult.
But the deeper change was economic. As maritime labor became less desperate, as alternative employment became available, and as the shipping industry modernized, the conditions that made crimping profitable gradually disappeared. The crimps themselves aged out of the trade or moved into other enterprises. Shanghai Kelly faded into San Francisco legend. Bunko Kelly's later years remain obscure, his claims of 2,000 victims neither fully verified nor convincingly debunked.
What the Overlooked Variable Reveals
The standard narrative of shanghaiing emphasizes the violence and the villainy—the drugged drinks, the trapdoors, the tunnels to waiting ships. These details are accurate. But focusing solely on the crimps misses the larger machinery. Shanghaiing was not a deviation from the 19th-century labor system. It was that system taken to its logical extreme.
When an economy creates acute demand for labor that workers don't want to perform at the wages offered, and when legal structures treat workers as instruments rather than individuals, someone will find a way to fill the gap. The crimps were entrepreneurs responding to market conditions. The captains were customers. The politicians and police were silent partners. The victims were commodities.
Understanding shanghaiing this way changes how we read other labor crises, past and present. The question is never simply whether bad actors exist—they always do. The question is what conditions allow them to operate at scale, in daylight, for decades. In 19th-century port cities, the answer was a labor market designed around the assumption that human beings could be bought, sold, and compelled. The crimps simply took that assumption literally.
