Newton is a city in and the county seat of Harvey County, Kansas, United States. As of the 2010 census, the city population was 19,132. Newton is located 25 mi (40 km) north of Wichita and is included in the Wichita metropolitan statistical area (MSA). The city of North Newton is located immediately north of the city, but it's not part of Newton.
In 1871, the Atchison, Topeka and Santa Fe Railway built a main line east-west through Newton.
From the earliest beginnings in 1871 to 1873 Newton came to be known as "bloody and lawless—the wickedest city in the west." This reputation was much due to the 1871 Gunfight at Hide Park, which ultimately resulted in 8 men being killed before, during and after the incident. In 1872 the western terminal for the Atchison, Topeka and Santa Fe Railway and the railhead for the Chisholm Trail were established here. Shortly after incorporation of the City in 1872, the Newton city council passed an ordinance prohibiting the running at large of buffalo and other wild animals.
