Future Starfleet officer and Federation Ambassador, Spock, was born in ShiKahr in 2230. Sarek and Skon, Spock's father and grandfather, were also both residents of Shi'Kahr. (ENT: "Two Days and Two Nights"; TAS: "Yesteryear")
In 2365, a holoprogram available to crewmembers of the USS Enterprise-D was "Shi-Kar Desert Survival, Vulcan". The program, with a code list number of 03-225, was listed in the exercise menu. (TNG: "The Emissary", okudagram)
ShiKahr, as it was spelled in the script for "Yesteryear", has also been spelled "Shi'Kahr", "ShirKahr", "Shirkar", and "Shi-Kar".
ShiKahr was shown in the background in the remastered version of "Amok Time".
The script and production report for the Star Trek: Enterprise episode "The Forge" (at wbm) established that the United Earth Embassy was in Shi'Kahr. According to senior illustrator John Eaves, both the embassy and the Vulcan High Command building were supposed to be in the same city as each other.
