Moral authority and religious head

Moral authority is an abstraction of a religion's strength, unity, and respect. Your religion's moral authority and its causes are visible in the Religion tab, while other religions' moral authority scores are visible in the Ledger.


High moral authority increases the speed and success rate of most types of religious conversion, including the likelihood of Pagans accepting foreign preachers. It also increases the size of holy orders. Low moral authority makes the rise and spread of heresy more likely.

Some religious actions require a minimum moral authority:


Moral authority is primarily affected by control of holy sites and success or failure in religious wars. The personal qualities of the religious head (if there is one) also matter. A full list of factors that affect moral authority follows:

Effect Moral Authority Duration
Base for organized religion (i.e. not unreformed pagan) 20% Permanent
Full control of holy site +10% Permanent
Partial control of holy site (bishop has religion but liege does not, or vice versa) +5% Permanent
Full control of unsettled holy site (no temple holding in province) +5% Permanent
Partial control of unsettled holy site (no temple holding, top liege's religion and county holder's religion differ) +2.5% Permanent
Diplomacy of religious head +0.5%/point Permanent
Piety of religious head +0.02%/point Permanent

  • The easiest way for pagans to increase their moral authority is to raid infidel temples and conquer infidel counties.
  • Give a holy site to the religious head (or hold it yourself if you're the Caliph or Fylkir). Catholics and Orthodox normally have the religious head controlling a holy site from the start, but other religions don't.
  • Ensure that your religion controls as many holy sites as possible. However, Jerusalem is a holy site to many Christian and Muslim sects; you will run the risk of triggering crusades and jihads early.
  • Getting moral authority high for the Indian religions is often not a priority (as they do not have heresies) and not an easy task (due to the absence of a religious head). Do note that Hindu rulers should aim to boost moral authority by securing Hindu holy sites, as their holy order (Followers of Arjuna) is notably large and can be used against non-Hindus. They can also raid temples as an alternative.
