Star Trek invented Klingon language for the fictional species of the same name.
 Dedicated Klingon enthusiasts, some but not all of whom were Star Trek fans, created the Klingon Language Institute, which published multiple magazines in the language
Certain elements of Klingon culture, resembling Japanese culture with honor at the forefront, were actually first explored with the script for the planned two-part "Kitumba" episode for the unproduced 1978 Star Trek: Phase II series
