There were several reasons why it took nearly 24 years for the Star Trek franchise to visit the Klingon home world, Qo’noS. The Klingons have been a major part of the franchise since their debut in Star Trek: The Original Series season 1, episode 27, “Errand of Mercy”, which aired in 1967. Sworn enemies of Starfleet and the Federation, Star Trek‘s Klingons continued to clash with Captain James T. Kirk (William Shatner) and the crew of the USS Enterprise until Star Trek VI: The Undiscovered Country.
