Hi all, my first time here - can someone clarify for me, do I have to keep at least 1 Holding in a County to control said county? What I mean is, I wasn't able to give the Mayorship of one of my cities to any one in my court, and the only reason I can think of is because it is the primary holding in the County. I've never had any problems giving such titles away before (when I've stripped it from someone else). The wikis are explict where this is concerned, that I could find...
Appreciate the help!
It sounds to me like you're quite confused, and I'm not totally sure the problem you are having is what you think... so I'm going to just throw out some explanations and hopefully something I say gets at what you are trying to describe. =)
You can only give away titles you already control. You won't be able to give that city away to anyone unless you hold the title to the CITY itself, regardless of who controls the county. If you do not hold the top-level holding in a county, you do not control the county directly but that does not dictate what other titles you might hold or give away. Note that you could, in fact, own a city in a county held by someone else, and that someone else could be either your vassal or totally independent of you.
You can only revoke titles of your direct vassals. That means that if you are a Duke and you have a count under you, you cannot go around revoking his barons' and his mayors' titles. That doesn't mean the land is no longer a part of your realm, it just means you no longer control every aspect of its governance. That's the feudal system. Note that you can still imprison dishonorable and plotting sub-vassals.
If you are only a count and you give away the county, that new count becomes independent of you. If you are a Duke and you give away a county, the lower vassals will become subservient to the count. You will no longer be able revoke the mayor's title.
If a city is a primary holding of a county, you will have a count-level mayor called a "Lord Mayor." If you happen to hold that title, you'll get a wrong-holding penalty as a feudal lord. If you give away the county to a courtier, you'll create a new Lord Mayor. Otherwise, it works just as it always would. However, if you wanted to keep the title, you could revoke the baron's castle and, as you are a feudal lord, the castle would immediately swap to become the primary holding. You could then give away the city, creating a regular baron-tier mayor and keep the county title.
Finally, if you are a Hindu, there are additional restrictions. You can only give holdings to members of the proper caste. Cities must be ruled by merchant castes, Castles by the noble caste, and temples by the priestly caste.
If none of this gets at what you are facing, let me know... try describing it in a bit more detail.
