Kang was one of the greatest Klingon warriors and diplomats to have served the Klingon Empire. He was the son of K'naiah. Kang was descended from Klingons who had become infected with the augment virus in the 2150s. Despite his difference from other Klingons, he rose to become a great military leader, strategist and diplomat, and had many skirmishes with the Federation. By the 24th century, he was made a Dahar Master and honored elder in the Empire.
