Before you learn to produce tanks or sign pacts, there are five numbers that shape everything else and that almost nobody explains all at once: stability, war support, manpower, political power and command power. None of them are optional — you'll be watching all five every single game, so it's worth understanding what they do from the start.
Stability
Measures how content your country is with you, as a percentage from 0 to 100%. The lower it drops, the worse everything runs: you lose production efficiency, your focuses take longer to complete, and you gain war support more slowly. It's not decorative — low stability quietly drags down an entire playthrough without it always being obvious why things feel harder than they should.
It rises through favorable laws, specific decisions, some focuses, and certain national spirits. It drops mostly from negative events and from governing under an ideology that doesn't match what your population actually wants.
War Support
Your population's willingness to sacrifice for the war effort, also 0 to 100%. It gates which conscription laws you can adopt (the more aggressive ones need a minimum) and grants direct bonuses once you're actually at war. Unlike stability, it usually starts low for most democratic and neutral nations — raising it before the fighting starts is part of the job.
Manpower
The pool of population available to form divisions. It's spent on recruitment and recovers very slowly, so it's not a resource you can burn through without a plan. Large nations (USSR, China, India) swim in manpower; small ones ration it carefully and make up for it with quality or defensive terrain instead of numbers.
Your active conscription law decides what share of your population is available: the more aggressive it is, the more divisions you can sustain, but the harder it also hits your civilian economy — fewer people left working the factories.
Political Power (PP)
The "currency" you spend to activate focuses, change national laws, and hire advisors. It accumulates on its own, slowly, so the real question isn't "how do I get more PP" but "what do I spend it on first." A classic beginner mistake is letting it pile up unused — idle PP does nothing for you.
Command Power
Used to hire and promote generals and field marshals, and to unlock their command traits as they gain experience. It's easy to forget about until you're already at war and short on quality commanders — worth building up a buffer before you actually need it.
Why They Matter Together
None of these five numbers live in isolation: low stability drags down your war support, low war support caps the manpower you can access, and without manpower or PP for the right laws, your army falls short exactly when you need it most. Keeping an eye on all five from day one — not just when things are already going wrong — is the difference between a game that flows and one that stalls without you quite knowing why.
