Overlord of Vulcan Philippa Georgiou (2257)
Overlord of Vulcan was a title held by the Terran emperor Philippa Georgiou in the 2250s. (DIS: "Vaulting Ambition")
Episode writer Jordon Nardino explained that this paternalistic and delusional title stemmed from Vulcan being an early conquest of the Terrans, who saw themselves as its protectors. [1]
