Provinces are controlled by establishing a garrison in the province. Once a garrison has been established, the ruler of the province controls the borders to the province, the entrance fees, and any taxes in the province.
The ruler of the province is the first noble seated in the castle to which the garrison is pledged. If there is no noble in the castle, the province is unruled.
Control of a province allows one to change its name or the name of any of its sublocations (name), disband the garrison (ungarrison), take items from the garrison, issue decrees to watch for certain units (decree), have the garrison attack specified units on sight (decree), control the borders (decree), set taxes (tax), and establish entrance fees (see Control of Locations).
The ruler of a province may grant certain privileges to other nobles by admitting them to his stack (see admit). (Note that you do not admit nobles to the province; you admit them to the ruler's stack.) Every noble on the ruler's admit list (either directly, or because his faction or nation is on the admit list) is given the following privileges: he may take and give items to garrisons, he is not charged taxes or entrance fees, and he may name the province (name). He is not permitted to turn borders on and off, set taxes or entrance fees, ungarrison, or issue decrees.
Nobles on the ruler's admit list are considered rulers as well for the purposes of market taxes (Sales Tax), etc.
