Integrating provinces in Europa Universalis 5 takes patience. It’s not like EU4 where you could core half a continent in a few years. In EU5, integration represents your government slowly absorbing new populations, cultures, and systems. If it feels slow, that’s because it is. But there are real ways to speed it up.
How Integration Works in EU5
Integration speed decides how fast conquered land moves through its administrative stages: Conquered, Integrated, and finally Core. You can start integration with the Integrate Province cabinet action. The time it takes depends on population size, culture, and your empire’s control.
Conquered provinces have high Separatism and low control
Integration progresses faster in culturally accepted or nearby regions
Bigger populations take longer to absorb
Integration stops entirely if control drops too low
Once integration completes, the province upgrades to Core if the majority population shares your primary or accepted culture.
What Affects Integration Speed
Several systems influence how fast provinces integrate. You can improve it through infrastructure, laws, and administrative strength.
Distance from your capital slows integration
Roads and proximity bonuses increase speed
High population of accepted cultures helps
Governors with strong administrative skills speed progress
Certain government laws give direct integration bonuses
The By Blood inheritance law increases integration speed by about ten percent, making it one of the few direct modifiers early in the game.
How to Integrate Faster
Integration is about stability and management more than just waiting. A province that’s fed, controlled, and culturally close will absorb faster than a poor, angry one.
Build roads to reduce distance penalties and increase proximity
Raise Control using armies or the Increase Control cabinet action
Feed the population to keep growth positive
Focus on nearby regions before expanding across continents
Use accepted culture policies to smooth assimilation
Avoid integrating massive, foreign populations early unless you’re ready for a long wait. Smaller border provinces finish faster and give better short-term gains.
The Role of Settlements
Your provincial rank also affects integration. Towns and cities integrate slower than rural settlements because their complexity takes longer to reorganize.
Towns have a small penalty to integration speed
Cities have a much larger one
Newly developed provinces might slow overall integration temporarily
For this reason, it can sometimes be better to integrate before upgrading settlements.
Final Blurb
Integration in EU5 isn’t meant to be quick. It’s a slow, political process that turns conquered land into something sustainable. Keep your provinces stable, build connections, and expand smartly. A patient ruler with roads and full control integrates faster than an empire constantly putting out fires.
FAQ
Why does integration take so long
Each province’s population, culture, and distance from your capital all slow the process.
How can I make integration faster
Use roads, stable control, accepted cultures, and the By Blood law to improve speed.
Do cities integrate slower
Yes, towns and cities have global penalties to integration speed due to their complexity.
Can low control stop integration
Yes, if control drops too low, integration progress will stall until stability improves.
What is the fastest way to integrate new land
Focus on nearby provinces first, maintain food and control, and develop infrastructure before starting large integrations.
