Bidaxsh

Bidaxsh ("bidakhsh", also spelled Pitiakhsh; in Roman sources "Vitaxa") was a title of Iranian origin attested in various languages from the 1st to the 8th-century. It has no identical word in English, but it is similar to a margrave, toparch and marcher lord. The title was prominent in Armenia and Georgia, being used by the military governor of a province, and being the hereditary title of the dynasts of Gugark.
The word was borrowed into Armenian as "Bdeašx" (բդեաշխ), and into Georgian as "Pitiaxshi" (პიტიახში) and "Patiaxshi" (პატიახში).
