"There is no victory without combat."-Kahless the Unforgettable

A humanoid warrior civilization and one of the major powers of the galaxy, the Klingon species originates from the planet Qo'noS (pronounced Kronos), an M-class planet. The Klingons are a proud, tradition-bound people who value honor. The aggressive Klingon culture has made them an interstellar military power to be respected and feared. Klingons believe that they have the instinctive ability to look an opponent in the eye and see the intent to kill.

History and Politics

Main article: Klingon history

File:Kahless.jpg

A clone of Emperor Kahless

The Klingon Empire was founded approximately 1,500 years ago by Kahless the Unforgettable, who performed many heroic feats including the unification of the Klingon people when he killed the tyrant Molor. Kahless came to be revered in Klingon society to the point of near-deification, and many aspects of Klingon culture came to revolve around emulation of Kahless's life. (TNG: "Rightful Heir")

According to an early draft of "Rightful Heir", Data gave the exact date of Kahless's death as 1547 years ago (from 2369), or AD 822. Also according to DS9: "Soldiers of the Empire", that the Earth calendar year of 2373 coincides with the year of Kahless 999.

The warrior ethos has been an important aspect of Klingon society since the time of Kahless, but the warrior aspects became much more dominant beginning in the early 22nd century. Previously, Klingon society was regarded as fair and balanced, but over time, the warriors gained greater prominence, to the point where the Klingons widely came to be regarded as a "warrior race." (ENT: "Broken Bow", "Judgment")

Because of their aggressive outlook, the Klingons have generally had poor relations with other races after they began to move out into space. Because the worlds of the Klingon Empire are resource-poor, the Klingons have developed an intense belief in the need for expansion and conquest in order to survive. The Klingons' relationship with Humans and the Federation has been rocky at best. Following the disastrous First Contact between Klingons and Humans, tense rivalries and unavoidable conflicts often developed between the two races. (TNG: "First Contact"),

In the year 2154, the Klingons gained access to the genetic material of human Augments, and tried to adapt this genetic engineering to improve themselves. An unanticipated side effect was that the Augment DNA caused the cranial ridges to dissolve. The test subjects did gain increased strength and intelligence, but then their neural pathways started to degrade and they died in agony. One of the subjects was suffering from the Levodian flu, which was modified by the Augment genes to become a deadly, airborne plague that spread rampantly among the Empire, from world to world. In the first stage of this plague, Klingons lost the ridges on their foreheads and began to look more human-like.

With the help of a Klingon scientist named Antaak, Dr. Phlox of the Earth starship Enterprise was able to formulate a cure that halted the genetic effects of the virus in the first stage, retaining the changes in appearance along with some minor neural re-ordering, but with no development of stage two characteristics, such as enhanced strength, speed, or endurance. This left millions of Klingons, mostly in the warrior caste, without their ridges. These alterations were even passed on to their children. (ENT: "Affliction, "Divergence")

The virus must have been cured sometime between 2269 and 2293, since we see Kang (lacking ridges in TOS: "Day of the Dove") with forehead ridges in VOY: "Flashback". It is most likely that it was before 2273, since that marks the first [re-]appearance of the ridges in the Trek timeline, in Star Trek: The Motion Picture. Fan speculation has also suggested that other differences in attitude and methodology between the TOS and non-TOS Klingons can be attributed to the neural re-ordering left by the virus.
It is possible that at first the treatment only gave many Klingons a single ridge from the nosebridge, across the forehead and then was eventually perfected and allowed a complete return to the original form. This speculation comes from the fact that many Klingon seen during the 23rd century possessed rather minor ridges (such as Chang, Korrd, and Azetbur).
It has been suggested that the disease afflicting the Klingons seen in the VOY episode "Prophecy", Nehret, is the modified Levodian flu. The Doctor manages to cure the Nehret using stem cells from B'Elanna Torres' daughter, who is 3/4 human and 1/4 Klingon, suggesting a similar method was used to cure the human-form Klingons.

Klingons were apparently so embarrassed by the fallout from their failed attempt at genetic enhancement that they refused to discuss the incident with outsiders. Due to the secrecy of the Klingon Empire, knowledge of the change became lost over time to the general population of the Federation. By the 24th century, the reason for smooth forehead Klingons was not widely known outside the Empire, and questions were generally met with a brusque answer along the lines of "we don't discuss it with outsiders". (ENT: "Affliction", ENT: "Divergence", DS9: "Trials and Tribble-ations")

It has been speculated that the events of the Temporal Cold War have complicated the "original" timeline of interstellar history. According to this theory, first contact between Earth and the Klingons was supposed to have occured during the Augment Crisis of 2154, but the Temporal Cold War altered historical events, causing the contact to take place prematurely in 2151.

In the year 2218, an incident occured between the Federation and the Klingon Empire which caused the two powers to become adversaries. By 2223, relations between the two powers had degenerated to a point of unremitting hostility, which would last for several decades. (TOS: "Day of the Dove", Star Trek VI: The Undiscovered Country, TNG: "First Contact")

The lingering tensions between Klingons and humans continued to rise, eventually leading to the Battle Of Donatu V near Sherman's Planet in 2245, and later erupted into what was considered the first Federation-Klingon War in 2267, that was quickly ended by intervention by the Organians after only four days of fighting. (TOS: "The Trouble with Tribbles", "Errand of Mercy") Over the next several decades, an uneasy peace developed that was broken by brief but fierce skirmishes and conflicts (Star Trek III: The Search for Spock, Star Trek V: The Final Frontier). A true and lasting peace finally came in 2293 with the signing of the Khitomer Accords, thanks to the efforts of Chancellor Gorkon and the Human Starfleet officer James T. Kirk. (Star Trek VI: The Undiscovered Country) Since then, despite several periods of rocky relations (see Second Federation-Klingon War), the Federation and the Klingon Empire have been steadfast allies, especially in the face of Dominion aggression in the 2370s. (DS9: "By Inferno's Light")

The Klingon relationship with the Romulan people is also extremely unstable. The Romulan Star Empire has been typically regarded by the Klingons as a "blood enemy" since at least the 23rd century. Sporadic Romulan attacks against Klingon colonies (see Khitomer Massacre) and interference in Klingon affairs (see Klingon Civil War) have continued to sour relationships between the two peoples. (TNG: "Sins of the Father", "Redemption, Part II")

The Klingons would join the Federation by the 26th century. (ENT: "Azati Prime")

Society

Klingon society is extremely complex, considered by some Federation citizens to be primitive in the extreme. It is based on a feudal system organized around traditional Great Houses of noble lineage, to which various parts of the population owe fealty. The Great Houses are traditionally represented in the Klingon High Council, which is led by a Chancellor.

Males traditionally dominate public life in the Empire, assuming the leading roles in politics and the military with only rare exceptions. TNG: "Redemption, Part I") A notable exception of the prohibition of women serving on the High Council came when Azetbur became Chancellor of the High Council after her father, Gorkon, was assassinated in 2293. (Star Trek VI: The Undiscovered Country) Women, in turn, traditionally dominate the household and the management of the family's affairs. (DS9: "You Are Cordially Invited...") Klingon women are treated as equals except in politics and matters of inheritance. They are prohibited by law from serving in the High Council and cannot take control of their Houses unless they have the money and no male successors of the lineage. Otherwise, it is expected of Klingon women to exhibit the same physical prowess and lust for blood and honor as the men.

Klingon society functions through a system of family reputation and honor. Tradition is an integral part of their lives and breaking from observances is considered a grievious insult to society that is not forgotten easily, bringing shame to the offender's name for several generations. Bloodlines and relations are also taken very seriously by any true Klingon. Lines comprise of more than mere family members. (TNG: "New Ground")

An integral part of tradition is the various rituals that mark milestones in a Klingon's life or the history of the Empire. Most notable of the rites is the Rite of Succession, which a future leader of the Empire must complete with a valid Arbiter of Succession (Captain Jean-Luc Picard in the case of Gowron) overseeing the proceedings. Before the Rite can begin, there's another elaborate ceremony needed to confirm the death of the previous leader. This is known as the Sonchi ceremony. (TNG: "Reunion") Individual Klingon warriors are expected to go through the Rite of Ascension to be recognized as a full adult. (TNG: "The Icarus Factor")

Klingons are extremely territorial. There is no such thing as an "insignificant corner of Klingon space". (ENT: Bounty).

Physiology

On average Klingons are larger and physically stronger than Humans, though they possess much less tolerance for cold weather (VOY: "Displaced", DS9: "Change of Heart"). Spock said once that Klingons lack tear ducts, however Klingon myth states that Kahless once filled the ocean with his tears. (Star Trek VI: The Undiscovered Country)

Oxygenated Klingon blood usually appears red in a Class M atmosphere, however in Star Trek VI: The Undiscovered Country, Klingon blood appeared pink/violet in one scene. It's possible this was done to keep the movie from being rated "R" in the U.S. market, although more likely, the Klingon blood for the movie was more expensive, and the regular red blood seen in the various tv shows was cheaper for their limited television budget. After all, Worf's gorch in Star Trek Insurrection was pink, implying Klingons actually do have pink blood. Then again, it could still be argued that because in Star Trek: Generations, B'Etor's blood was red, and that was in a motion picture. However, it still seems more likely that Klingon blood is pink in color, because of what Colonel Worf said in Star Trek VI: The Undiscovered Country regarding the difference in Klingon blood compared to humans. (This was when Colonel West was disguised as a Klingon and was shot down)

Internally, Klingon anatomy is markedly different from that of Humans. There is a great deal more multiple redundancy in their organs, a principle they call brak'lul. This allows Klingons to survive severe injuries in battle. They have twenty three ribs, two livers, an eight chambered heart, three lungs, and even redundant neural function and multiple stomachs. Some geneticists believe the extra organs, notably the third lung, evolved to give Klingons greater stamina on the battlefield. Surprisingly, Klingons have relatively little knowledge of their own biology and their medicine is very poorly developed. This is largely due to their warrior traditions - a Klingon who is wounded is expected to be left to survive or die through his own strength, or to undergo the Hegh'bat, a form of ritual suicide. (TNG: "Ethics", VOY: "Lineage")

Klingon pregnancies normally run thirty weeks, but with mixed species, gestation times are shorter. The odds against Klingon-human conceptions are rather high; however, when successful, Klingon and human metabolisms sometimes clash causing biochemical fluctuations in the mother, which may lead to fainting. Klingon traits remain dominant for several generations, even with a single ancestor, therefore a child even 1/4 Klingon will still possess forehead ridges if he or she carries the gene. (VOY: "Lineage")

Klingons have ridged spines and feet. (TNG: "Ethics", ENT: "Broken Bow") After birth some Klingon infants may experience a pronounced curvature to the spine, which may be corrected for by surgery. This "defect" tends to run in Klingon families, especially among females. Federation medicine, fortunately, has advanced beyond that allowing an additional choice of treatment which involves genetic modification. (VOY: "Lineage")

When Klingon children enter their teenaged years, and begin growing into an adult, they go through jak'tahla, a Klingon form of puberty. (Star Trek: Insurrection)

Doctor Julian Bashir once sarcastically noted that the natural oder produced by Klingons was comparable to "vanilla with a hint of lilac". (DS9: "Trials and Tribble-ations")

Religion and Tradition

File:KlingonDeathRitual.jpg

Klingon death ritual

Ritual is a very important element in Klingon society. The Klingons are not a religious people as such - they do believe that deities existed at one time, but the Klingons slew their gods about a thousand years ago as they were considered to be more trouble than they were worth. They believe that once a Klingon has died the spirit exits the body, leaving behind a worthless shell to be disposed of. (VOY: "Emanations") In the Klingon death ritual, it is traditional for those on hand to howl into the sky as a warning to the afterlife that a Klingon warrior is about to arrive. (TNG: "Heart of Glory"; DS9: "Tears of the Prophets") In some cases a funeral dirge is sung in memory to the deceased, or friends will sit with the body to protect it from predators, a practice known as Ak'voh. (DS9: "The Ship")

Furthermore, a Klingon, who is unable to fight, hence is unable to live as a warrior anymore, has the traditional obligation of committing the Hegh'bat, which is the Klingon ritual suicide. Tradition dictates that a close friend, or eldest son must assist. That person's role is to hand the dying Klingon a knife so that he can plunge it into his heart, remove it and then wipe the blood on the sleeve of the person assisting. (TNG : "Ethics")

The Klingon afterlife is divided into two branches; the dishonored are taken to Gre'thor aboard the Barge of the Dead, a vessel captained by Kortar, the first Klingon. Kortar was the one who originally killed the gods who created him, and was condemned to ferry the dishonored to Gre'thor as a punishment. Once in Gre'thor, the dishonored are watched over by Fek'lhr, a vaguely Klingon-esque figure. It is tempting to view Fek'lhr as the Klingon equivalent of the Human devil, but according to Kang, the Klingons have no devil. (TNG: "Devil's Due", VOY: "Barge of the Dead" & TOS:"Day of the Dove".)

Those who die honorably go to Sto-vo-kor, where Kahless was said to await them. (TNG: "Heart of Glory", "Rightful Heir", VOY: "Barge of the Dead")

Klingon rituals include the R'uustai, a bonding ceremony which joins two people together in a relationship similar to brotherhood. (TNG: "The Bonding") Klingon tradition holds that "the son of a Klingon is a man the day he can first hold a blade." (TNG: "New Ground")

If a Klingon warrior strikes another Klingon with the back of his hand, it is interpreted as a challenge to the death. Klingon warriors speak proudly to each other; they do not whisper or keep their distance. Standing far away or whispering are considered insults in Klingon society. (DS9: "Apocalypse Rising")

When going into battle, Klingon warriors often sing the traditional warriors' anthem, which is essentially an invocation to Kahless and a pledge to win a good death in battle. (DS9: "Soldiers of the Empire")

Background

Klingons were introduced in Star Trek: The Original Series, and first appeared in the episode "Errand of Mercy". At the time, they appeared as fairly ordinary humans with heavy makeup and mustaches (although their appearance changed even within the original series, with dark makeup and heavy eyebrows being the norm, but the Klingons of "The Trouble With Tribbles" being much lighter-skinned and human-like in appearance). Beginning with Star Trek: The Motion Picture, improved makeup techniques, and bigger budgets, led to their present elaborate forehead designs.

After DS9: "Trials and Tribble-ations" made the change in appearance part of the canon, the Star Trek: Enterprise episodes "Affliction" and "Divergence" explained the differences.

Note that the Klingons in Star Trek VI were given pinkish blood specifically for ratings and plot purposes; Klingon blood on TV is red. Also, even individual Klingon makeup (Worf's head, for example) can change from episode to episode. According to David Alexander, in Star Trek Creator, a biography of Gene Roddenberry, Roc Books, 1994, the Klingons were named for Lieutenant Wilbur Clingan, a friend of Roddenberry who served with him in the Los Angeles Police Department.

The only Star Trek cast members, besides Michael Dorn and Roxann Dawson, to have worn the full Klingon makeup include Avery Brooks, Colm Meaney, Rene Auberjonois, Kate Mulgrew, Ethan Phillips and Scott Bakula.

A story Robert O'Reilly tells in an interview in the DS9 Season 7 DVD, is that a long running joke among actors who have played Klingons, is that they do not want to appear in the films, as, he believes, that the only purpose of a Klingon in one of the films was to be killed off. He was proven right in Generations.
