Aurora is an eastern suburb of Denver and a Home Rule Municipality spanning Arapahoe, Adams, and Douglas counties in Colorado. The city is the third most populous city in the state of Colorado and the 56th most populous city in the United States.
It originated in the 1880s, as the town Fletcher, taking its name from Denver businessman Donald Fletcher who saw it as a real estate opportunity. He and his partners staked out four square miles east of Denver, but the town – and Colorado – struggled mightily after the Silver Crash of 1893. At that point Fletcher skipped town, leaving the community with a huge water debt. Inhabitants decided to rename their township Aurora in 1907, and it slowly began to grow in Denver’s shadow becoming the fastest growing city in the United States during the late 1970s and early 1980s.
