What Kian means
Kian means ancient or enduring in its Irish reading, from cian, long-lasting. The Persian kiani means royal, from the Kayanian dynasty of Iranian legend, and the two share nothing but a spelling.
Where Kian comes from
The Irish Cian, from cian meaning ancient or long, belonged to the son-in-law of Brian Boru who fought at Clontarf in 1014; it anglicizes as Kian or Keane. The Persian Kian is entirely separate, from kiani, royal, referring to the legendary Kayanian dynasty of the Shahnameh. Both communities use the name in Britain today for unconnected reasons, which is why reference works stack ancient and king without explaining the jump — the same pattern our Idris entry describes.
