Dispite the considerable sophistication of klingon technology, significant gaps exist in Klingon 
medical science, in part due to cultural biases that injured warriors should be left to die or to  
carry out the Hegh'bat, a ritual meaning as much as suicide using a "D'k Tagh"knive which is 
impaled into the chest, the son or friend would than remove it and cleane it on his sleeve. The 
crowning achievement of any Klingon's life is to die with honor, and preferably in a honorable and  
glorious battle, hence the saying "It is a good day to day" before going into battle. 

According to myth, ancient Klingon warriors slew their gods a millennium ago. They apparently  
were more trouble than they were worth. Perhaps this is why the Klingons have no devil; They 
killed him. 

In Klingon society, the death of a warrior who has died honorably is not mourned. in such cases, 
The survivors celebrate the freeing of the spirit by gathering around the body, than the eyes of  
the fallen warrior ar pried open and let loose a powerful howl, which is discrebed as an  
exaltation of the victorious. Klingon beliefs hold that the howl is a warning for the dead to be  
aware because a Klingon warrior is about to arrive. in other cases, a sacred funereal dirge is  
sung in memory of the deceased. Klingons believe in an afterlife but there is no burial ceremony. 
They dispose of the body in the most efficient means possible, confident that the warrior's spirit  
has now joined Kahless the Unforgettable, who was said to await those who were worthy for 
Sto-Vo-Kor, a mythological place of the afterlife for the honored dead. 

Klingon tradition holds that "the son of a Klingon is a man the day he can first hold a blade". 
Another Klingon ritual is the R'uustai, or bonding ceremony, in which two individuals join 
families, becoming brothers and sisters. Klingons believe that they have the instinctive ability  
to look an opponent in the eye and see the intent to kill. Another Klingon tradition holds that a  
Klingon who dies by their own hand will not travel across the river of blood to enter Sto-Vo-Kor. 
If a Klingon warrior strikes you 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 

The Klingon nation was founded some 1.500 years ago by 'Kahless the Unforgettable', who first   
united the Klingon people by killing the tyrant, Molor. The first contact between the Klingon Empire  
and the United Federation of Planets took place in 2218, which was a disastrous event that led to   
nearly a century of hostilities between the two powers.   

In 2268 the Klingon Empire entered into a brief alliance with the Romulan Star Empire, which   
resulted in the sharing of military technology and spacecraft designs, providing the Romulans with  
Klingon battle cruisers, and the Klingons with cloaking technology.   

Then in 2293 a catastrophic explosion occurred on the Klingon moon Praxis, which caused serious  
environmental damage to their Homeworld and the destruction of their key energy resources.   
In the economic disarray that followed, the Klingon Chancellor Gorkon, leader of the Klingon High  
Council, found that his empire could no longer afford its massive military forces. Gorkon therefore  
launched a peace initiative, offering to end some 70 years of hostilities with the Federation.   

During the century that followed, the Klingon High Council was a hotbed of political intrigue. So in   
2367 the Empire was nearly plunged into civil war when the Council Leader K'mpec died of poison.  
This murder, viewed as a killing without honor under Klingon tradition, triggered a bitter struggle to  
determine K'mpec's successor. K'mpec had taken the unorthodox precaution of appointing a   
non-Klingon as his Arbiter of Succession, namely the renowned Captain Jean-Luc Picard of the   
U.S.S. Enterprise NCC-1701-D. Under Captain Picard's mediation, political newcomer Gowron   
emerged as the sole candidate for Council Leader.   

Then in 2368 the Klingon Empire endured a brief but bitter civil war, when forces loyal to the   
powerful Duras family unsuccessfully attempted to block Gowron. Though their nation is called   
an empire, an emperor has not ruled it for more than three centuries. This situation changed   
rather dramatically in 2369, when the clerics of Boreth produced a clone of Kahless the   
Unforgettable. Although their initial claim that the clone was the actual Kahless was quickly   
disproved, this clone was regarded as the rightful heir to the throne, and with the support of the   
High Council Leader Gowron, was initiated as the ceremonial Emperor of the Klingon people.   

In 2371, the station Deep Space 9, was drawn into a conflict between the Klingons and the  
Cardassians, which led to the treaty breakup by Gowron and  enter yet again a hard time with 
tremendous conflicts and battles with the Federation. A year later though, when the Federation 
was in a full-scale war with the Dominion, Gowron had to save the Klingon Empire from a possible 
total destruction. He was forced to reinstate the khitomer accords, and join the Federation in a  
glorious, and honorable battle.
