The Age Of Scientific Acquisition
After the city-state age, Klingon scientific knowledge began to grow at a rapid pace. Part of this rapidity in growth stems from the philosophic-theological beliefs of Klingon culture. Their philosophy of the honor to be gained in taking knowledge from Durgath, coupled with the expansionist and aggressive Klingon attitude led to the exploration of the practical sciences with no religious notions to overcome.
Of the strongest early clans, the clan of Katook had the greatest and fastest development of science. K'tar Katook and his successor K'shen both supported the notion that children who were not strong physically, and who would normally have been killed, might be mentally strong and useful in the wresting of scientific knowledge from K'nash'akar. All theld children were given until the age of seven to show acuity at some field. If they did not, they were considered kuve despite their lineage. They were sent to the Year Games as line soldiers for the other theld-youth to command in their battles. If they survived the Year Games, they would be assigned some menial task to perform for the state. This was before the discovery of other life forms and thus, before the concept that Klingon and kuve were incompatible. By the time other life forms were discovered, educational practices had advanced so that every Klingon was able to learn some useful aspect, even if it was only loading torpedo bays on a warship.
K'shen set up the first state run schools. Those theld-youth who exhibited an aptitude for strategy and leadership were sent to the school of K'tali'ket, a military academy, while those with talent in the sciences (including theory, mechanics, etc.) were sent to K'somi'ket.
Many wars developed between the various clans over the sciences. The largest of these wars was the nIvveS in which K'shen and other descendants of Kapek's Kamorh'dag nation defended their scientific knowledge against K'akant and other nations, which collectively called themselves the Gevish'rae. This was the beginning of the Kamorh'dag/Gevish'rae rivalry of which traces can still be seen today
This war, which was filled with hate and familial conflict unlike that seen on many other planets, produced two things useful to the Klingon future. It provided unity between the various clans according to their Kamorh'dag/Gevish'rae loyalties and it produced the thoughts of Kang the Seer. Both of these developments were essential in the future unification of Klinzai.
