Ancient West

The Ancient West, also known as either the "The Wild West" or "The Old West," was used to describe the mid and late period of 19th century Earth when the western United States was being settled. This period in Earth's history would be frequently romanticized in Earth literature and other media.

The Enterprise NX-01 discovered a settlement of Humans and Skagarans on a planet in the Delphic Expanse that resembled the towns of Earth's Ancient West. It was discovered that the ancestors of the Skagarans living on the planet had kidnapped several thousand humans from the American Ancient West in the mid 19th century, whose descendants continued to live on the planet. The crew left learning materials for the population, such as a history of Earth since the 19th century, and stated that Earth would someday offer to take the settlers back to Earth.

In 2268, the Melkot trapped James T. Kirk and his landing party in an incomplete recreation of the American Ancient West town of Tombstone, Arizona. The Melkot were testing Kirk and his crew with a reenactment of the infamous gunfight at the OK Corral. (TOS episode Spectre of the Gun)

Deanna Troi was introduced to stories of the Ancient West by herfather, Ian Andrew Troi, who often read her such tales when she was a child.

In 2369, Worf, his son, Alexander Rozhenko, and Deanna Troi participated in a holodeck adventure set during the Ancient West in the town of Deadwood, South Dakota. The program was designed by Alexander and Reginald Barclay. Troi, Worf and Alexander were playing this program when an experiment being conducted by Geordi La Forge and Data malfunctioned. This malfunction caused a number of changes in the program, such as causing the other characters to look like Data and even removing the holodeck safeguards, making 19th century weapons deadly.
