How do you deal with Nobility in your game?
Note: The following questions are very general in nature, so sorry for not being ultra specific.
1) How do you institute it? (Talent points then deeds by PC's/NPC's, or some other method)
Generally or all PCs start nobles (like the campagin I'm kicking off), or they roll for it, randomly.
2) Do nobles have to prove it to other, and how do they? (I know how they did it in the middle ages but do you do it that way?)
In my games, generally, all citizen must have some form of "credential", a real document issued by the King/Emperor/whatever.
These documents assess the identity of the citizen in question. Not having this credential is a pain in the a....
In addition to this nobles have some distinguishing mark:
right to bears coat of arms, fine clothings, house ring, renown and reputation ("It's the king!") and, generally speaking, they announce themselves to local nobles.
Finally, on medieval times, taking a "word" had special means. Today we are much more distrustful, but in an age of personal interactions, words were the law.
Example: during a siege in north France, a besieging english night called the castlehold knight, praying him to open the gate and watch at the danger he and his men were exposed.
After the french knight requested an "assurance" (a spoken promise) that no one tried to storm the castle and that his inclumy was not at stake, he opened the gate and, arriving near the english knight, watched the exposed wooden foundations of the tower he was standing minutes ago.
Suprised but thankful, the castlehold knight "assured" that he, and his men, were prisoner of the english knight (not english army) and that he needs only a day to prepare his men to leave the castle".3) What benifits dos it give or entail?
First, in battles nobles (knights) were not killed, if found wounded on the field, but taken prisoner for a ransom. Not always ...
Second, a noble was taken seriously on his "assurances" since his honor was at stake. Nobles rarely betrayed their words.
Third, generally nobles were not charged for what we call taday "crimes". Not if these crimes happened against not "gentle" folks.
Nobles, generally, were welcomed hosts of local nobles, when on travel. Not to abuse, though.
Nobles were generally rich. Often, expecially man-at-arms, were poor if they didn't loot. Not a good position.
Nobles weren't
generally hated by peoples nor mistrusted.
4) What drawbacks does it have?
Middle ages were much more less "chaotic" than movies and books tell us but...
Nobles were not expected to take part to sacks and dead depredations. Their men though...
Nobles were not expected to rape.
Nobles were expected to protect noble women from their own men. This was a nasty affair after months of sieging and battles...
Nobles were expected not to handle money directly.
Nobles, in the rare case were judged, often were condamned to death.
Nobles were often prey of envy, expecially if near influencial or powerful person (King, Duke, Emperor).
Nobles were expected to protect their peoples in case of war and raise an adequate army.
Last but not least ... nobles couldn't swear and must pay higher taxes (and are closely watched by king's men)
