Derby was settled in 1642 as an Indian trading post under the name Paugasset by John Wakeman of New Haven, though fur traders had been in the area before and Native Americans had lived there for centuries. In 1651, the first year-round houses were completed, at that time the New Haven Colony had recognized Paugasset as a town. The residents of the town of Milford protested Paugassets' recognition as an independent town and, as a result, the order was rescinded and Paugasset returned to the Milford jurisdiction. In 1675, the former plantation of Paugasset was admitted as the township of Derby by the state legislature, named after Derby, England.  Derby was incorporated on May 13, 1775. 
In 1836, The Colman Brothers began The Birmingham Iron Foundry on the corner of Main Street and Water Street. It employed between 100-125 and was one of the many manufacturing businesses thriving in the city in the 1800s. In 1927, the company merged with Farrel Corporation of nearby Ansonia and renamed Farrel-Birmingham Corporation. The Derby Facility closed and was razed in 2000 to make way for a Home Depot. The Ansonia division is still in business and opened their new plant in the Fountain Lake Commerce Park in 2017.  
In the 19th century, both corsets and hoop skirts were manufactured in the city. The Kraus Corset Factory is the oldest major factory building to survive from Derby's corset manufacturing period. It was built by Sidney A. Downs, opened in 1879, and expanded in 1910. In 1987 it was added to the National Register of Historic Places. In the 1990s it was converted to apartments and underwent a second addition, a first floor parking garage and three stories of apartments added on the north side along Roosevelt Drive ( Connecticut Route 34).

National Humane Alliance Fountain
The city has resurrected its National Humane Alliance fountain – a century-old granite structure with lion-head spigots—as part of a gateway entrance plaza at the Division Street entrance to the Derby Greenway. The fountain was given to the City in 1906 by the National Humane Alliance and erected at the intersection of Seymour and Atwater Avenues. The water was first turned on on June 1, 1906. Years later it was moved to Founders Commons when traffic patterns made its original location a problem. It fell into disrepair and was not used as a fountain while on Founders Commons. When the Derby Greenway was built, the fountain was moved to its new location on June 22, 2006, fully restored with new plumbing and new lions heads and formally dedicated with the surrounding Derby Hall of Fame Plaza on September 1, 2007.  The fountain has three levels, the top level contains spigots in the shape of lion's heads for humans, below is a large circular bowl for horses, and at the base are smaller bowls for dogs and cats.

Several years later, $3,200 was pledged for a remodel of the existing base and the addition of an upper base and a 7 ft bronze statue, bringing the total height of the monument to 21 ft 4in. The remodel and addition was constructed by Maurice J. Power of New York City, the sculptor of the bronze statue is unknown. The dedication of the remodel/addition was held on July 4, 1883 and was attended by approximately 8,000 people.  The monument was restored in 2018 for a cost of $75,000. 
Old Derby Uptown Burial Ground (Colonial Cemetery)

On November 16, 2001, 94 year-old Ottilie Lundgren, of Oxford, was brought to Griffin Hospital in Derby experiencing difficulty breathing and cold-like symptoms. Based on Lundgren's symptoms and her rapidly deteriorating condition, doctors suspected and began testing for anthrax. A response was made to the hospital from the Federal Bureau of Investigation, Centers for Disease Control and Prevention, Connecticut State Police, Connecticut State Health Department, and Derby Fire Department HAZ-MAT team. The test was confirmed and treatment began, however it was unsuccessful and Lundgren died on November 22, 2001, making her the fifth and final victim of the 2001 anthrax attacks. Derby and Griffin Hospital made worldwide news for days following the incident and most major news outlets provided 24-hour news coverage for updates on Lundgren's condition. Investigators thought that the anthrax was delivered in a letter via the United States Postal Service to her home in Oxford, however no suspicious letters were found, and the exact route of exposure was never determined. Post Offices in Seymour and Wallingford were investigated, as they were the only two post offices that sent mail to Lundgren's home, however both facilities were determined to be clean. Lundgren's home in Oxford was also quarantined and searched by the Federal Bureau of Investigation and Connecticut State Police, however nothing was found that indicated how Lundgren had been exposed.    In 2008, following a lengthy investigation that repeatedly came up empty, the FBI's primary suspect was Bruce Edwards Ivins, an American microbiologist, vaccinologist, and senior biodefense researcher at the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) at Fort Detrick, Maryland. However, Irvins took his own life shortly after the FBI named him as the primary suspect, no formal charges or direct evidence has been found to substantiate these accusations. In 2010, the FBI closed the investigation into the attacks.  
On December 6, 1985 at approximately 3:45pm EST, a three-story brick building, located at 268 Main St, Derby, collapsed following a natural gas explosion killing 6 people and injuring dozens. Natural gas had seeped into the sewer line following construction in the area, the River Restaurant, located on the main level of the building had 18 customers and employees inside when the explosion occurred. Residents and businesses within a 10 block radius were evacuated as a precaution while firefighters worked to find those trapped in the debris. The Connecticut Fire Marshals Office, Connecticut State Police, and The National Transportation Safety Board investigated and found a crack in a four-inch cast iron pipe near the explosion site. Connecticut's "Call Before You Dig" program is a direct response to this incident.  
On August 12, 1991 at approximately 6:56pm EST, a fire broke out in the basement of a three-story, six-family home located at 269 Caroline Street. First arriving units found heavy fire in the nearly 100-year-old building along with reports of multiple trapped residents. The fire department rapidly struck a second and third alarm for additional resources from the surrounding area, including Ansonia, Shelton, Seymour, and Orange. In total, 18 people escaped or were rescued from the building, however a mother and her two children were killed in the fire. The Fire Marshal's Office investigated and determined the cause of the fire was accidental.  
August 10–12 of 1955 brought heavy rain to the east coast from Hurricane Connie saturating the ground. A week later when Hurricane Diane passed through, the rain water had nowhere to go. As a result, the Housatonic and Naugatuck Rivers over flowed their banks and devastated the Housatonic and Naugatuck River Valley areas.  The crest of the Naugatuck River reached 25.70 ft above flood stage, the highest in recorded history, which it still maintains to this day.  Low-lying cities in the area, such as Derby, Shelton, Ansonia, Seymour, Beacon Falls and Oxford all suffered impacts from the flood. In total, 87 people were killed and an estimated $200 million(1955) or $1.8 billion(2018) in damage was reported.
