Denver

• 1. Introduction

  ›

  Denver sits at exactly one mile above sea level, a fact so precise that engineers marked the benchmark on the steps of the State Capitol building. That single measurement defines the city's identity more than almost anything else. But the Mile High City began as something far more chaotic: a scrappy claim-staking operation on the western edge of the Kansas Territory, born during a gold rush, built on contested land, and eventually transformed into the economic engine of the American Mountain West.

  On the 22nd of November 1858, General William Larimer planted cottonwood logs on a bluff overlooking the confluence of Cherry Creek and the South Platte River, staking a townsite he named Denver City to curry favor with Kansas Territorial Governor James W. Denver. There was one awkward problem: Governor Denver had already resigned from office. The city's name was a political gesture aimed at a man who no longer held power. Yet the name stuck, the town grew, and by 1876 Colorado entered the Union with Denver as its capital.

  The questions worth asking about Denver are not just about growth and geography. They are about who was displaced, who arrived, who thrived, and who was left behind. They are about a city that turned down the Olympics, legalized marijuana before any other major American city, and built a performing arts complex second in size only to Lincoln Center. They are about a place whose identity has always been shaped by the mountains just to its west and the plains stretching endlessly to its east.

• 2. Land and Dispossession

  ›

  The 1851 Treaty of Fort Laramie had already defined Cheyenne and Arapaho territory as stretching from the North Platte River southward to the Arkansas River, a definition that specifically encompassed the land of modern Denver. That recognition lasted less than a decade. The discovery of gold in November 1858 in the Rocky Mountains brought a flood of white immigration across those treaty lands, and Colorado territorial officials quickly pressured federal authorities to shrink the extent of Indian-held territory.

  On the 18th of February 1861, six chiefs of the Southern Cheyenne and four of the Arapaho signed the Treaty of Fort Wise at Bent's New Fort near what is now Lamar, Colorado. The agreement ceded more than 90 percent of the lands guaranteed by Fort Laramie. Many Cheyenne challenged the treaty's legitimacy: only a minority of chiefs had signed, they argued, the signatories had not understood what they were agreeing to, and gifts had been used to secure signatures. The territorial government dismissed these objections, declaring the treaty a solemn obligation and labeling those who refused to abide by it as hostile.

  The dispute escalated into the Colorado War of 1864 and 1865, during which the Sand Creek massacre of Cheyenne and Arapaho people occurred. The Medicine Lodge Treaty that followed stipulated their removal from their traditional territory entirely. The treaty was never legally ratified by tribal members as its own terms required, yet the relocation was carried out. By the end of the 1860s, the Denver area had been cleared of its indigenous inhabitants, and the city that bore a resigned governor's name was free to grow.

• 3. Rails, Riches, and Ruin

  ›

  When the nation's first transcontinental railroad was routed through Cheyenne rather than Denver, the young city faced a crisis. The railroad passed a daunting 100 miles away, and without a rail connection, Denver's future as a commercial center was uncertain. Territorial Governor John Evans, along with David Moffat and Walter Cheesman, launched a fundraising drive that gathered $300,000 within three days. The momentum stalled before enough capital was secured, forcing those same leaders to take direct control of a debt-laden railroad. On the 24th of June 1870, the Denver Pacific completed the link to the transcontinental line, and the city's fortunes changed.

  Prosperity attracted the wealthy and the ambitious. Horace Tabor, the Leadville mining millionaire, built a business block at 16th and Larimer and erected the Tabor Grand Opera House. Luxurious hotels appeared, including the Brown Palace, and mansions rose for Denver's elite, among them the Croke-Patterson-Campbell Mansion at 11th and Pennsylvania. Immigrant laborers from Germany, Italy, and China arrived to work in the factories, followed by African Americans from the Deep South and Hispanic workers. The population of different groups strained housing and bred social tension.

  Then the Silver Crash of 1893 arrived and upended everything. Denver entered a depression, and in the same period between 1880 and 1895 crime bosses like Soapy Smith worked alongside elected officials and police to control elections, gambling, and fraud. After World War I, a revival of the Ku Klux Klan spread into Denver and into urban areas across the Midwest and West, feeding on anxiety among white, native-born Americans uneasy about rapid social change. The city that had raised $300,000 in three days for a railroad had also shown it could absorb the worst of American social pathologies.

• 4. The Rocky Flats Shadow

  ›

  From 1953 to 1989, a Department of Energy nuclear weapons facility called the Rocky Flats Plant operated roughly 15 miles from Denver, producing the fissile plutonium pits used in nuclear warheads. A major fire at the facility in 1957, combined with leakage from nuclear waste stored on-site between 1958 and 1968, resulted in the contamination of parts of Denver with plutonium-239, a radioactive substance with a half-life of 24,200 years.

  In 1981, Jefferson County health director Carl Johnson published a study linking that contamination to elevated rates of birth defects and cancer in central Denver and the areas closest to Rocky Flats. Later research confirmed many of his findings. The contamination did not stay within the plant's boundaries; plutonium was detected outside the former site and continued to present risks decades later, including to the proposed Jefferson Parkway, a road project intended to complete Denver's automotive beltway.

  The Rocky Flats story sits uncomfortably alongside Denver's image as an outdoor, sunshine-filled city. Its mountains and clean air draw millions. Yet for nearly four decades, a weapons plant on its western edge left a radioactive mark that no amount of development could fully erase.

• 5. The Olympics Denver Refused

  ›

  In 1970, Denver was selected to host the 1976 Winter Olympics, timed to coincide with Colorado's centennial celebration. It was a moment of civic pride. Then, in November 1972, Colorado voters rejected ballot initiatives that would have allocated public funds for the games, and the Olympics moved to Innsbruck, Austria. Denver became the only city in history to decline to host an Olympiad after being selected.

  The movement that killed the Denver games was driven largely by environmental concerns and was led by State Representative Richard Lamm. His victory at the ballot box launched a political career: Lamm went on to be elected to three terms as Colorado governor, serving from 1975 to 1987. The episode revealed a city willing to say no to international prestige when the cost seemed too high.

  Denver explored a potential bid for the 2022 Winter Olympics, but no bid was submitted. The original refusal, the source notes, made subsequent Olympic bids more difficult. A city that turned down the games once has had to reckon with that decision ever since.

• 6. Civic Culture and the Outdoor Life

  ›

  Apollo Hall opened soon after Denver's founding in 1859 and staged plays for early settlers. By the 1880s, Horace Tabor had built the city's first opera house. In July 1982, Denver hosted the World Theatre Festival at the Denver Center for Performing Arts: 114 performances of 18 plays by theatre companies from 13 countries over 25 days. Today the Denver Performing Arts Complex is the second-largest performing arts center in the nation, after Lincoln Center in New York City.

  In 1988, Denver-area voters approved the Scientific and Cultural Facilities Tax, a 0.1 percent sales tax supporting cultural institutions. The tax was renewed in 1994 and 2004, and in 2016 a ballot measure extended it to 2030, passing with 62.8 percent of the vote. That sustained public investment reflects a city willing to tax itself for museums, theatres, and science centers.

  Denver's outdoor reputation is rooted in geography as much as culture. The city owns approximately 14,000 acres of mountain parks, including Red Rocks Park, home to the Red Rocks Amphitheatre. It also owns the mountain on which Winter Park Resort operates in Grand County, 67 miles west of downtown. Since 1974, Denver and surrounding jurisdictions have rehabilitated the South Platte River for recreational use; the Greenway running along the river extends 35 miles into Adams County and won the Silver Medal Rudy Bruner Award for Urban Excellence in 2001. As of the last available count, 89 percent of Denverites live within a ten-minute walk of a park.

• 7. Politics and Firsts

  ›

  In March 1969, Rodolfo "Corky" Gonzales and his organization the Crusade for Justice hosted the First National Chicano Youth Liberation Conference in Denver, making the city one of the centers of the Chicano Movement. Gonzales, a boxer-turned-activist, had built the Crusade to fight police brutality and advocate for bilingual education. Denver's large Mexican-American population, one of the largest in the United States, has shaped the city's political and cultural character ever since.

  In 2005, Denver became the first major U.S. city to vote to legalize the private possession of less than an ounce of marijuana for adults 21 and older. The measure passed with 53.5 percent of the vote. Then-mayor John Hickenlooper noted at the time that the city could not override state law, which already treated marijuana possession similarly to a speeding ticket. Denver pushed again in May 2019, becoming the first U.S. city to decriminalize psilocybin mushrooms after an initiative passed with 50.6 percent of the vote; the state followed by legalizing it in 2022.

  Denver hosted the Democratic National Convention in both 1908 and 2008, the second occasion serving as the centennial of the first. The city also hosted the G7 summit between June 20 and 22, 1997, and in 1972 hosted a Libertarian Party National Convention notable for nominating Tonie Nathan for vice president, the first woman and the first Jewish person to receive an electoral vote in a United States presidential election. On the 3rd of October 2012, the University of Denver hosted the first of the three presidential debates between Barack Obama and Mitt Romney.

• 8. A City of Teams and Trade

  ›

  Denver holds a notable distinction in American sports: it is the smallest metropolitan area in the country to have a team in all four major sports leagues. The Denver Broncos have sold out every regular-season home game since 1970, excepting strike-replacement games, and have advanced to eight Super Bowls, winning back-to-back in 1997 and 1998 and again in 2015. The Colorado Avalanche, who relocated from Quebec City in 1995, have won three Stanley Cups: in 1996, 2001, and 2022. The Denver Nuggets won their first NBA championship in 2023.

  The city's economy runs on more than sports spectacle. Eight Fortune 500 firms have headquarters in Denver. The Denver MSA recorded a gross metropolitan product of $311.9 billion in 2023, ranking it the 18th-largest metro economy in the United States. The energy sector remains significant: when oil prices dropped from $34 a barrel in 1981 to $9 a barrel in 1986, nearly 15,000 oil industry workers in the area lost their jobs and Denver recorded the nation's highest office vacancy rate at 30 percent. The sector recovered; the region now employs around 700 petroleum engineers, and advances in hydraulic fracturing have made the DJ Basin of Colorado an active oil play.

  The 105th meridian west of Greenwich, the longitudinal reference for the Mountain Time Zone, passes directly through Denver Union Station. That geographic fact has quiet economic consequences: Denver's position allows telecommunications companies to communicate with both North American coasts, South America, Europe, and Asia on the same business day, a practical advantage that has drawn Dish Network, Starz, and other telecom firms to the city. In 2024, Denver-based Ibotta's initial public offering was the largest tech IPO in Colorado's history.
