The main methods of increasing loyalty are:
  • Bestowing titles.
  • Marrying princesses to the general (the incest vice is possible if the general has royal lineage).
  • Keeping the general in close proximity to the faction leader. A general in the leader's stack gets loyalty pretty quickly, and cannot lead a revolt since the faction leader is always the commander of his stack. But keeping a general in the same province or within a couple of provinces from the leader helps.
  • Increasing the Influence of the faction leader. This is key, a low Influence king is a prime target for a civil war.
