Corona was founded at the height of the Southern California citrus boom in 1896, advantageously situated at the upper end of the Santa Ana River Canyon, the only significant pass through the Santa Ana Mountains. The town of Corona, once laid claim to the title "Lemon Capital of the World." A museum there presents the lemon's former role in the local economy. It derived its name (and its nickname, The Circle City) from the curious layout of its streets, with a standard grid enclosed by the circular Grand Boulevard. Also, the renowned circular Grand Boulevard is where three international road racing events took place in 1913, 1914 and 1916. In more recent years it has been known as the Gateway to the Inland Empire. Prior to the 1980s, Corona was a largely agricultural community, dominated by citrus orchards, ranches, and dairy farms. Sky-high real estate prices in Los Angeles and Orange counties made the area's cheap land desirable to developers and industrialists, and by the late 1990s it was considered a major suburb of Los Angeles. In recent years, Corona has changed from a working-class bedroom community for Orange County and the larger cities of the Inland Empire to a full-fledged edge city in its own right, with industrial parks opening near Norco and luxury housing developments rising in the foothills of the Santa Anas. The development of commerce and industry in the city has been accelerated by congestion on the Riverside Freeway, with many firms leaving northern Orange County to be closer to their employees' homes in Corona and Riverside. The construction of the Chino Valley Freeway nearby has also linked Corona to the Pomona and San Gabriel valleys, with the result that the once largely white and Latino city has experienced an influx of Asian American residents who commute to Asian-oriented businesses in cities such as Alhambra and Diamond Bar. Corona was also home to the Corona road race, a Grand Prix race in the early 20th Century.
In 2002 the city government considered an initiative to secede from Riverside County and form an autonomous Corona County because the city government and some residents were dissatisfied with how services were handled in nearby areas. The effort was also considered by areas in other cities in the western part of the county including Murrieta. Whether nearby cities such as Norco, California would have been included in the new county are unknown. The proposed county would have been bordered by San Bernardino County to the northwest and by Orange County to the west.
