City in Sedgwick County, Kansas

Derby is a city in Sedgwick County, Kansas,

For many millennia, the Great Plains of North America were inhabited by Native Americans. From the 16th century to the 18th century, the Kingdom of France claimed ownership of large parts of North America. In 1762, after the French and Indian War, France secretly ceded New France to Spain, per the Treaty of Fontainebleau.

In 1802, Spain returned most of the land to France. In 1803, most of the land for modern day Kansas was acquired by the United States from France as part of the 828,000 square miles (2,144,512 km2) Louisiana Purchase for 2.83 cents per acre. In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U. S. state. In 1867, Sedgwick County was established within the state of Kansas, which included the land for modern day Derby. In 1870, settlers John Haufbauer and J. H. Minich built the first houses, smithies, and general stores on the site that would become Derby. In 1871, the community was named El Paso, after El Paso, Illinois, and was laid out and platted. In 1880, the Atchison, Topeka and Santa Fe Railway changed the name of its rail station to Derby, after railroad official C. F. Derby, to avoid confusion with El Paso, Texas.

In 1903, the city incorporated with the name El Paso, but the city remained largely a rural community until after World War II. The aviation industry had begun its growth in Wichita during the 1920s, and when the demands of the war required more airplanes, businesses such as Boeing, Cessna and Beechcraft flourished. Boeing was located a few miles north of the city, which provided a close place for workers to live. Throughout the Cold War, Boeing maintained military contracts and kept jobs nearby. In 1952, the Air Force took over Wichita Municipal Airport and founded McConnell Air Force Base between Wichita and Derby. Many airmen found homes in Derby when space on base became occupied. From 1950 to 1956, the city population grew from 432 to approximately 5000 people.

The city manager is hired by the City Council and Mayor to carry out policies, oversee City operations, and ensure that the entire city is being served. The Governing Body establishes goals and policies which the staff executes under the supervision of the city manager. The mayor is elected by the city at large, and eight council members are elected to represent four wards. Elections are nonpartisan and held in November of odd numbered years.

The museum houses thousands of historical artifacts, including an 1870 log cabin and one of the largest displayed collections of arrowheads in Kansas. Exhibits at the museum include a school room, a general store that has a collection of antique pharmaceutical items, an original two horse covered wagon that traveled to the Derby area from North Carolina in the 1860s and so much more.
