Harvey County began as a railroad center, with the City of Newton located on the Chisholm Trail. Cattle travelled along the Chisholm Trail from Texas, and were loaded on railroad cars in Newton for shipment to eastern cities. The railroad continues to be an important industry in the County. Later, Mennonites from Russia settled in Harvey County, and brought with them red winter wheat seeds that thrived in Harvey County and the Kansas plains. The Mennonites also established Bethel College located in North Newton.
