Before European settlement, the land that now makes up Aurora was the territory of the Arapaho, Cheyenne, Ute, and Sioux tribes. These lands were
claimed by France in 1682 and subsequently became part of the 1803
Louisiana Purchase. Aurora originated in the 1890 as the town of Fletcher, taking its name from Denver businessman
Donald Fletcher who saw it as a real estate opportunity. He and his partners staked out east of
Denver, but the town—and Colorado—struggled mightily after the
Silver Crash of 1893. The Town of Fletcher was incorporated on May 5, 1903. By February 1928, the town of Aurora had reached a population of over 2,000 and it was reincorporated as a city on March 9. In 1943, the hospital was the birthplace of 2004 Democratic presidential candidate
John Kerry. President
Dwight D. Eisenhower recovered from a heart attack at Fitzsimons for seven weeks during the fall of 1955. Decommissioned in 1999, the facility is part of the
Anschutz Medical Campus of the
University of Colorado Denver, and the
Fitzsimons Life Science District. The Anschutz Medical Campus also includes the
University of Colorado Hospital, which moved to Aurora from Denver in 2007, and the
Children's Hospital. The first carbon-ion
radiotherapy research and treatment facility in the U.S. has been proposed at the site. These facilities will employ a workforce of 32,000 at build-out. In 1965, mayor
Norma O. Walker became the
first woman to head a U.S. city with a population over 60,000. In 1978, the cult coming-of-age film
Over the Edge was filmed in Aurora; the crime drama has been named the "signature film" of Denver. In 1979, it was announced that a science fiction theme park would be built in Aurora using the sets of a $50 million film based on the fantasy novel
Lord of Light. However, due to legal problems the project was never completed. The script of the unmade film project, renamed
Argo, was used as cover for the "Canadian Caper": the exfiltration of six U.S. diplomatic staff trapped by the
Iranian hostage crisis. In 1993,
Cherry Creek State Park on the southwestern edge of Aurora was the location for the papal mass of the 8th
World Youth Day with
Pope John Paul II, attended by an estimated 500,000 people. Aurora is split among three counties and lies distant from the respective county seats. A
consolidated city and county government such as those found elsewhere in Colorado (
Denver and
Broomfield) was considered in the mid-1990s but failed to win approval by city voters; the issue was reconsidered in 2006. Aurora Sports Park opened in 2003. In 2004, Aurora was honored as the
Sports Illustrated magazine's 50th-anniversary "Sportstown" for Colorado because of its exemplary involvement in facilitating and enhancing sports. The city attracts more than 30 regional and national sports tournaments annually to Aurora's fields. Aurora's active populace is also reflected in the variety of professional athletes
hailing from the city. Aurora's first semi-professional sports franchise, the
Aurora Cavalry in the
International Basketball League, began play in 2006 but folded by season's end due to budget mishaps. In 2008, Aurora was designated an
All-America City by the National Civic League. Aurora pioneered the use of
bank filtration in the United States, becoming one of the first U.S. cities to reap the benefits of siphoning water from beneath a riverbed upon completion of the Prairie Waters Project in 2010. In 2017, the
Republic of El Salvador opened a consulate in Aurora, serving Colorado,
Kansas,
Nebraska, and
Wyoming. In 2024, the
Republic of Honduras opened the city's second diplomatic post. La Plaza, the largest
Hispanic food hall in the United States, opened in Aurora in 2024.
Aurora theater shooting On July 20, 2012, Aurora was the site of the deadliest shooting by a lone shooter in Colorado (and the state's overall second deadliest, after the 1999
Columbine High School massacre). The shooting occurred just after midnight, when
James Holmes opened fire during the
midnight premiere of
The Dark Knight Rises in a
Century movie theater, killing 12 people and injuring 70 others. Holmes was arrested and was eventually sentenced to 12 life sentences in prison with an additional required 3,318 years. The shooting drew an international response from world leaders. U.S. President
Barack Obama visited victims, as well as local and state officials, and addressed the nation in a televised address from Aurora on July 22. Actor
Christian Bale, who plays
Batman in the film, also visited some victims in hospitals. The events marked a turning point in recognition and public perception of the city; rather than referring to the site as being in "Denver" or "suburban Denver", as would have been typical before the event, virtually all media accounts of the incident unequivocally named "Aurora" as its location.
Elijah McClain On August 30, 2019,
Elijah McClain died six days after an unprovoked detention by two Aurora police officers. On June 27, 2020, Aurora Police in riot gear dispersed thousands of protestors at a
violin concert held in his honor. On October 12, 2023, one of the officers involved in McClain's death was found guilty on charges of assault and
negligent homicide, while another officer was acquitted on all charges against him, which included assault and reckless manslaughter.
2024 U.S. Presidential Election Aurora received national media attention during the run-up to the
2024 U.S. presidential election. In September 2024, statements made by mayor Mike Coffman and city council member Danielle Jurinsky, both Republicans, falsely claimed that the Venezuelan
Tren de Aragua gang had taken control of an Aurora apartment complex and was extorting residents for their rent money. Jurinsky appeared on
Fox News alleging "a huge cover-up" and that this "isn't just an Aurora issue." Presidential candidate
Donald Trump repeated the claims during his September 10 debate with
Kamala Harris, and subsequently scheduled a campaign rally in Aurora. Mayor Coffman denied the city was overrun by Venezuelan gangs. At the October 11 rally at Aurora's Gaylord Rockies Resort & Convention Center, Trump intensified his remarks regarding undocumented immigration and proposed an "Operation Aurora" to remove undocumented immigrants connected to gangs. At a press conference held the same day at Aurora's
Stanley Marketplace to denounce Trump's rally, Colorado Governor
Jared Polis said, "We welcome the eyes of the nation on a true Colorado gem, the great city of Aurora." Following Trump's inauguration,
U.S. Immigration and Customs Enforcement conducted raids targeting suspected Tren de Aragua gang members in Aurora and Denver. During a
speech to a joint session of Congress on March 4, 2025, Trump falsely claimed immigrants “destroyed” Aurora and that the city had “buckled under the weight of migrant occupation.” The apartment complex at the root of the controversy was eventually shut down by a court order describing it as a threat to public safety. Aurora's police chief, who advocated for the closure, stated that property mismanagement was to blame, and not gang activity among tenants. ==Geography==
