The population begins to grow steadily in the Wyoming Territory, which is established on July 25, 1868, after the arrival of the railroad.

Unlike Colorado to the south, Wyoming will never experience a rapid population boom in the nineteenth century from any major mineral discoveries such as gold or silver.

The Union Pacific Railroad had reached the town of Cheyenne, which will later become the Wyoming state capital, in 1867.

The railroad will eventually span the entire state, boosting the population, and creating some of Wyoming's largest cities, such as Laramie, Rock Springs, and Evanston.

The name Wyoming is used by Representative J. M. Ashley of Ohio, who introduces a bill to Congress to provide a "temporary government for the territory of Wyoming".

The name "Wyoming" had been made famous by the 1809 poem Gertrude of Wyoming by Thomas Campbell.

The name is derived from the Delaware (Munsee) name meaning "at the big river flat", originally applied to the Wyoming Valley in Pennsylvania.
