Cheyenne (/ʃaɪˈæn/ or /ʃaɪˈɛn/) is the capital of the U.S. state of Wyoming. It is the principal city of the Cheyenne, Wyoming Cheyenne Metropolitan Statistical Area which encompasses all of Laramie County, Wyoming. The population was 53,011 at the 2000 census. It is the county seat of Laramie County and the largest city in Wyoming. On July 4, 1867, General Grenville M. Dodge and his survey crew platted the site now known as Cheyenne (Dakota Territory, later Wyoming Territory). There were many from a hundred miles around who felt the construction of the Union Pacific Railroad through the area would bring them prosperity. By the time the first track was built into Cheyenne four months later (November 13), over four thousand people had migrated into the new city. Because Cheyenne sprang up like magic, according to newspaper editors visiting from the East, it became known as "Magic City of the Plains"[citation needed]. Those who stayed and did not leave with the westward construction of the railroad were joined by gamblers, saloon owners, thieves, opportunists, prostitutes, displaced cowboys, miners, transient railroad gangs, proper business men, soldiers from "Camp Cheyenne," later named Fort D.A. Russell (now F.E. Warren Air Force Base), and men from Camp Carlin, a supply camp for fifteen[citation needed] northern army posts on the frontier.
