I know its an old thread. Just provide some details that I cannot find on the internet.
To be recognized as a king, the condition is:
1. You are not occupying any castle that the faction wants (If you want to get recognized by King Graveth, you must not occupy any castle that Graveth wants)
2. You and the faction are not in war and have the same enemy (If you want to get recognized by King Graveth and you only rule a castle in far northern area of Vaegirs, you may declare war to any Roddocks' enemy and send a guy to King Graveth. You will then get recognized.)
