siege and conquest

Cities and settlement change hands during time of both war and peace but what if the players wish to wage war or more simply take control of a settlement weather for an NPC a Quest or just fun.
There are a few simple ways to take over a city.
Hostile. Kill any one who resists you the guards who disobey die show them your absolute power and hope no one betrays you, First step will be to eliminate/subjugate all the guards and nobles depending on how public and successful this is there may or may not be a Peasant Rebellion when you claim your place as leader. Machiavelli would be proud run with fear be brutal 
Diplomatic you commune with either the people, the guards and or the noble to relieve the current governors of there power. communing with the people can lead to a Peasant Rebellion which can lead to a coup or stepping down of the local noble. communing with the guards can lead to a Martial Rebellion which will lead to a coup or the stepping down of the local noble (In general Guards demand more then the peasants but are far more successful then Peasant Rebellion) Or you may be able to cause a Martial Strike in which the guards refuse to work this can help a Peasant Rebellion succeed. Finally by talking to the noble you can get him to willingly sign away the land and settlement but if done in a deceptive or threatening way can lead to a Martial Rebellion against you in your near future. Bribery; Money may not buy you happiness but it sure does get the job done one of the most common forms to sway a crowd is with cash, it should take around 1000-2000 GP to but a crowed of Peasants depending how good the current leader is and general quality of life but in some circumstances where the nobles grip is well established or the new leaders are disliked they may be completely unwilling to join and the same is said for the Guards but they tend to cost 10 to 50 times as much depending on the Guards current pay, skill and numbers but promises of greater pay can lower this amount but if not provided as promised a Martial Strike/Rebellion could be Imminent.
puppeteering The act of controlling ones leader either through deception intimidation Bribery or just plain persuasion, get your self to rule without changing much on the surface. there are many ways to do this and its not perfect your puppet may misbehave or even try to get rid of you.
