History[]
Narudian IV was one those worlds were a Starfleet officer reaching out to shake hands could start an interstellar incident. This was covered at Starfleet Academy in the Interspecies Protocol class. On Narudian IV, an outstretched hand was considered a declaration of war.
In the Kelvin timeline, Freshman cadet Nyota Uhura learned about this fact when she participated in the class in 2255. She confused it briefly with Glakota, where an outstretched hand was an invitation to a private rendezvous. (TOS - Starfleet Academy novel: The Edge)
