Overview
Klingons are a humanoid people whose later screen histories centre on warrior traditions, family houses and contested honour. The Empire's relationship with the Federation moves between war and alliance; it cannot be inferred from a single captain's attitude. Discovery's T'Kuvma invokes Kahless as a model for imperial unity while attacking the Federation. The Next Generation's Rightful Heir brings the same founding tradition into a different political crisis: a purported returned Kahless is exposed as a clone. He becomes a symbolic Emperor while Chancellor Gowron retains governmental power. Religious authority and political command therefore need not belong to the same person.
Worf and Voq are devoted believers despite occupying vulnerable positions. Worf's human upbringing and Voq's skin colour make them outsiders in the histories compared by the official guide. Noble status also constrains careers: Kor blocks the young commoner Martok from an officer's commission, and Martok later doubts that the High Council will accept him as Chancellor. Worf ultimately defeats Gowron and yields the position to Martok. These events make house membership and inherited prestige consequential without reducing all Klingon identity to aristocratic birth.
Honour also functions as a standard used against rulers. Duras conceals familial treachery and murders opponents, while Gowron endangers Martok's troops to diminish a political rival. Their conduct contradicts the ideals they claim to uphold. Rightful Heir places Worf's spiritual uncertainty at the centre of an episode, rather than treating Klingon faith as automatically secure. Early Original Series presentation differs from later depictions; neither the changing makeup nor one period's imperial policy supplies a universal account of Klingon anatomy or values.
Worf's commitment to warrior training does not exclude peace. He teaches mok'bara as a way to centre mind and body, accepts that his son's future peacemaking is a worthy cause, and later cultivates meditation. Such choices belong to his evolving interpretation of Klingon practice, rather than a newly revealed rule requiring every Klingon to become pacifist.
First appearances & development
Errand of Mercy introduced Klingons on screen in 1967. Subsequent productions developed a much fuller house-based political culture. Rightful Heir premiered on May 17, 1993, directed by Winrich Kolbe from Ronald D. Moore's teleplay and James E. Brooks's pitch; Discovery later dramatized an earlier imperial era.
Canon & continuity
Stobie's complete official comparisons supply contrasting political actors and Worf's changing practice, including his defence of peacemaking. The complete Rightful Heir feature verifies the episode's production and faith-centred premise. The essays' character parallels are interpretations of screen stories; individual misconduct and personal commitments are not assigned to the entire people.

Family, evolution & connections
Neville Page’s helmet-concealed 2009 Klingon concepts
Page says the uncovered Klingon heads in Star Trek Into Darkness let him develop ideas conceived for the helmeted Klingons in the 2009 film. His account describes several years of design gestation. It concerns the reboot films’ makeup development, not an in-universe evolutionary change or the origin of the species across all Star Trek continuities.

The Klingons ( KLING-(g)on; Klingon: tlhIngan [ˈt͡ɬɪŋɑn]) are a humanoid species of aliens in the science fiction franchise Star Trek.
Developed by screenwriter Gene L. Coon in 1967 for the original Star Trek (TOS) series, Klingons were humanoids characterized by prideful ruthlessness and brutality. Hailing from their homeworld Qo'noS (in the Klingon language pronounced /ˈq͡χoʔnoʂ/, but usually rendered as /ˈkronos/ in English), Klingons practiced feudalism and authoritarianism, with a warrior caste relying on slave labor and reminiscent of Ancient Sparta. With a greatly expanded budget for makeup and effects, the Klingons were completely redesigned for Star Trek: The Motion Picture (1979), acquiring ridged foreheads. In subsequent television series and in later films, the militaristic traits of the Klingons were bolstered by an increased sense of honor and a strict warrior code similar to those of bushido, and a view of the afterlife similar to that of the Ancient Scandinavians.
Klingons are recurring antagonists in the 1960s television series Star Trek, and have appeared in all subsequent series, along with ten of the Star Trek feature films. Initially intended to be antagonists for the crew of the USS Enterprise, the Klingons became a close ally of humanity in Star Trek: The Next Generation. In the 1990s series Star Trek: Deep Space Nine, humans and Klingons join with the Romulans to fight the Dominion.
Among the elements created for the revised Klingons was a complete Klingon language, developed by Marc Okrand from gibberish suggested by actor James Doohan. Spoken Klingon has entered popular culture, even to the extent that some of the works of William Shakespeare and parts of the Bible have been translated into it. A dictionary, a book of sayings, and a cultural guide to the language have been published. According to the Guinness World Records, Klingon is the world's most popular fictional language as measured by number of speakers.
