Bidaxsh 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 etymology of the term is disputed, and it has been interpreted as literally meaning "the eye of the king," "second ruler" or "vice king." The word was borrowed into Armenian as Bdeašx (բդեաշխ), and into Georgian as Pitiaxshi (პიტიახში) and Patiaxshi (პატიახში).
