8 American Cities With Fascinating Origin Stories

On a warm July morning in 1701, a French military officer named Antoine de la Mothe Cadillac led about a hundred men in a fleet of canoes along a ribbon of water connecting Lake Huron to Lake Erie. When he found the spot he wanted — a bluff on the north shore where he could see boats coming from both directions — he stepped ashore and planted New France’s flag. He called the post Fort Pontchartrain du Détroit, borrowing the French word détroit, meaning “strait.” The city that grew from that bluff kept the last word.

Cadillac’s goal wasn’t just exploration — he wanted to block British traders from squeezing into the region’s lucrative fur trade and to build a colony that could actually sustain itself through farming. He had lobbied the French crown for two years before getting the go-ahead. The Anishinaabe people had lived in this river country for centuries before Cadillac arrived, and they would shape the settlement’s early character as much as any European plan.

When Jean-Baptiste Le Moyne, Sieur de Bienville, picked the site for La Nouvelle-Orléans in 1718, his engineers told him it was a terrible idea. The land sat in a curve of the Mississippi Delta, much of it at or below sea level, regularly swamped by the river and the lake. Bienville pushed ahead anyway. Control of the Mississippi meant control of the entire interior of the continent, and this bend in the river was the key to that.

The city was named for Philippe II, the Duke of Orléans, who was regent of France at the time. Its original French Quarter still sits on the natural levees — the slightly higher ground deposited by centuries of flooding — while later growth spread into the lower bowl. That engineering bet has been renewed and renegotiated every hurricane season for three hundred years.

In the fall of 1858, a prospector named William Larimer arrived at the junction of Cherry Creek and the South Platte River and found a cluster of rough camps buzzing with gold fever. He promptly staked out a town, named it Denver City — after Kansas territorial governor James W. Denver — and began selling lots. There was just one problem: Governor Denver had already resigned his post. Larimer didn’t find out until after the name was set, and by then it had stuck.

The camps around Cherry Creek were a chaotic patchwork of rival settlements. Auraria, across the creek from Denver City, was founded by the same Green Russell party whose gold discoveries had started the Pike’s Peak rush in 1858. By 1860 the two towns had merged. The gold that sparked it all turned out to be modest, but Denver had already become the supply hub for the entire Rocky Mountain mining world — a role that mattered far more in the long run than any single strike.

In 1867, a one-armed Civil War veteran named Jack Swilling was riding through the Salt River Valley when he noticed something peculiar in the desert floor: long, straight ridges of earth that didn’t look natural. They were the remnants of an elaborate irrigation canal system built by the Hohokam people, who had farmed this valley for over a thousand years before their civilization collapsed sometime in the 1400s. Swilling formed an irrigation company, hired workers to dig out the old channels, and within months the desert was growing wheat.

When the new settlement needed a name, a well-traveled Englishman named Darrell Duppa suggested Phoenix — the mythical bird that rises from ashes — because a new civilization was literally being built on the bones of an old one. The name was formally adopted in 1870. Today Phoenix sits atop one of the ancient world’s most sophisticated water engineering systems, most of it still buried under the city’s streets.

In the mid-1750s, the spot where the Allegheny and Monongahela rivers meet to form the Ohio was the most strategically valuable piece of land in North America — and both France and Britain knew it. The French got there first, throwing up Fort Duquesne in 1754 after chasing away a half-built British fort. Four years later, British General John Forbes led an army through the Pennsylvania wilderness, the French blew up their own fort rather than let it fall, and Forbes named the site Pittsburgh for William Pitt, the British prime minister.

Fort Pitt followed on the same ground, and a town grew up around it. What nobody fully anticipated was the geology: the confluence of three rivers made Pittsburgh a natural funnel for coal and iron ore, the raw ingredients of steel. Andrew Carnegie built his first steel mill here in the 1870s. The name Forbes gave it in honor of a politician turned out to fit an industrial titan instead.

In the summer of 1847, a wagon train of 148 Mormon pioneers crested the Wasatch Mountains and looked down into a vast, treeless valley ringed by more mountains and drained into a salt lake with no outlet. Most travelers would have kept moving. Their leader, Brigham Young — who viewed the scene from a wagon bed, sick with Rocky Mountain spotted fever — reportedly said, “This is the right place.” They stopped.

The choice was intentional. Young wanted a place far beyond the jurisdiction of the United States, where his community could practice their faith without interference. (Within a year, the Mexican-American War made the Salt Lake Valley American territory anyway, but Young had already laid out a grid of broad streets centered on Temple Square.) The city that emerged was a planned settlement in the most literal sense — streets wide enough to turn a four-horse wagon, blocks oriented to the compass, and water rights mapped out before the first winter.

Las Vegas — “the meadows” in Spanish, named for the artesian springs that once made it a watering stop on the Old Spanish Trail — was largely empty desert until May 15, 1905, when the San Pedro, Los Angeles and Salt Lake Railroad held a land auction on the dusty flat. In a single afternoon, investors bought up 1,200 lots. A town materialized almost overnight around the railroad junction.

The gambling halls and hotels that define Las Vegas today came decades later, after Nevada legalized casino gambling in 1931 and the construction of Hoover Dam brought thousands of workers to the region. The original settlers of 1905 were mostly railroad workers and small businessmen who had no idea their tidy grid of lots would eventually become the entertainment capital of the world. What they did know was that if you controlled the water and the tracks in the Nevada desert, you controlled everything else.

In January 1847, a small Mexican settlement called Yerba Buena — “good herb,” named for a wild mint that covered the hills — officially changed its name to San Francisco, hoping to claim the identity of the magnificent bay it sat beside. At the time, the population was somewhere around 200 people. Then, in January 1848, gold was discovered at Sutter’s Mill, about 130 miles away.

Within two years, the population of San Francisco had exploded past 40,000. Ships arrived and were simply abandoned in the harbor when their crews jumped ship to go prospecting — some of those hulls were later buried under landfill and became part of the city’s foundation. The sleepy village of Yerba Buena was buried too, not by earth but by the sheer velocity of a city that arrived all at once, from everywhere on earth, chasing the same impossible dream.
