Unless that deserving noble is said irish count. If he is weak, competent, loyal or whatever virtue one can find good for a vassal, why notI just dont understand how a count in Ireland, can hold a county smack in the middle of the Holy Roman Empire. How was that correspondence? I assume medieval lords were very very respectful and polite at the time since the Holy Roman Empire let's you have that county, visit it etc and no questions asked.
If I were the Holy Roman Emperor I would have a good laugh, then politely tell that Irish count to **** ***, you ***** ****** ****!
(Taking the province myself and give it to a deserving noble)
