I found that as the King of Abyssinia in the Iron Century start, I can holy war the Shirazids, whom I do not border either by land or by sea, for the Duchy of Afar:
The reason seems to be that the holy war CB only checks if you border the de jure target duchy, not if you border the recipient, so since my realm borders the de jure duchy of Afar, I'm able to holy war anyone for it, regardless of whether out realms share a border or not.
AFAIK, the holy war CB hasn't been changed recently, so does anyone know if this is the intended behavior, or an age-old bug that hasn't been fixed?
