Legitimacy is a measure of how legitimate a monarch appears to his or her people. It is presented as a score between 0 and 100. A score of 50 gives no bonuses or penalties with 0 and 100 giving full penalties and full benefits respectively. Legitimacy is only relevant to monarchies.

Legitimacy is tied to a particular monarch. When a new king takes the throne, legitimacy will be set to a new value based on the heir's claim strength. Newborn heirs will generally have a claim strength based on their parent's legitimacy, however.

Legitimacy Gain and Loss

There are a number of ways to gain and lose legitimacy. Note that there are other ramifications for some of these methods.


All gains are a percentage per year except for shifts due to inheritance, Monarch death or events.




  • Claim Throne Diplomatic Action: -20%
  • Changing Form of Government: -1/2 of current total
  • Losing an offensive war: -20%
  • New dynasty takes throne: Set to 20%

Effects of Legitimacy

Each effect is scaled so that the full bonus is received at 100, the full penalty at 0, and no effect at 50.

In addition, at legitimacy below 50, a nation is vulnerable to having its throne claimed, prompting a succession war.
