[[File:Prosperity screenshot.jpg|500px|thumb|right|An event that occurred due to having high prosperity in a province]]

'''Prosperity''' is a mechanism that allows provinces which have not been besieged, raided, or ravaged by disease for a long time to gain certain bonuses, such as extra tax income and faster replenishment of levies. Independent dukes or higher can set one of their [[demesne]] provinces to be their Crown Focus for additional yearly increase and events. On the flip side, prolonged diseases or sieges in a province will cause '''Depopulation''', resulting in reduced taxes and slower levy replenishment. Prosperity (and Depopulation) require {{icon|trd}} [[The Reaper's Due]] DLC.

==Crown Focus==

Rulers can set a province as their Crown Focus if they are:
* Duke tier or higher<!-- (tier requirement is hidden in the potential section!) --> 
* Not [[nomadism|nomadic]]
* Any of:
** Independent
** Vassal duke with 35 [[Realm#Realm size|realm size]]
** Vassal king with 55 realm size
** Vassal with republic, [[merchant republic]], or [[holy order]] government

A crown focus province gains a small bonus to its hidden prosperity value each year, as long as it is not occupied or experiencing an epidemic [[disease]].
===Effects of high prosperity & crown focus===
A crown focus province that already has a high prosperity level is eligible for special events. These events are more frequent with high stewardship and learning skills.
* At prosperity level 2, a province with a different culture can be converted at the cost 100% of your yearly income. It also converts the province's religion and removes the [[nomad agitation]] modifier, if relevant.
* At prosperity level 3, a new [[settlement]] slot can be created for 250% of yearly income.
* At prosperity level 3, various positive modifiers can be added to the province:

| province terrain is forest or jungle
|-
!Ore Mine

-10% build cost

|-
!Regimental Ground

| 
|}

Note that the "Jewish Settlement" and the "Minority Settlement" modifier are basically the same. They are split into two different modifiers just for historical/roleplaying purposes.

==Increasing prosperity==
Each province has a hidden prosperity value that can increase in small increments. When it reaches 100/250/500, the prosperity level increases.

Every province has a chance to gain points yearly. The chance increases with owner stewardship skill, owner prosperity bloodline, "sign of prosperity" from adulthood rites, heavy rain, [[great works]], or a local [[trade post]]. The chance decreases with war (especially being the primary attacker), various province maluses, or [[tribalism|tribal]] government. The amount of this passive increase depends on the [[terrain]], with coastal provinces getting a boost if they contain a city.

The [[ambition]] to [[File:Obj_see_realm_prosper_5.png]] "See the Realm Prosper":
* Enables some [[RIP flavor events|flavor events]] that increase prosperity
* If peace is successfully maintained for 5 years, the ambition succeeds and adds 35 points to every eligible province in the entire realm (not just demesne!)

[[Council]]ors can increase prosperity:
* Certain job actions add 6 points when successful:
** Marshal: train troops
** Steward: oversee construction
** Spymaster: study technology
** Spiritual: advance cultural technology
* Passive [[Job flavour events]] for council members:
** Any councilor with 12+ skill and {{smart}} can trigger a "good at job" event
** Marshal or steward with 15+ skill can offer to improve capital

Many peacetime decisions increase prosperity:
* Most [[Decisions#Minor|feasts and festivals]] add 8 points
* A completed tournament adds 15 points
* {{icon|tog}} [[Ancestor Worship]] can increase prosperity if you wish for economic assistance
* {{icon|tog}} For defensive pagans, having certain patron deities may increase prosperity<!-- TOG.7520 -->

Other events:
* A fleet returning with [[raiding|loot]] adds 12 points in your capital. Limited to once every 5 years (unless you change capital).
* Several {{icon|wol}} [[WOL Business Events|events from Way of Life]], with the Business [[focus]]
* Random opportunity to perform charity, if you have a province with a [[Hospital]]
* Random opportunity to invest in provincial apothecaries, if you have a [[Court Physician]]
* When a {{icon|jd}}[[Honorary_titles#Chinese_specialists|Master Engineer]] improves your demesne province, prosperity also increases.

==Loss of prosperity==

Disease, looting, and sieges can wipe the progress toward the next prosperity level, and sometimes even drop an entire level. Occupation of holdings will often reset the province's prosperity level to 0.
