HRE One True Faith

[zenisar]

I still play around with my Bohemia campaign on 1.7.3 version, learning the game by trying various possibilities the game gives me. As HRE emperor, I just converted to protestant faith in 1535 in this scenario, expecting that as other HRE princes will follow, the emperor will gain IA as advertised in UI. But nope, that is not the case. I do not lose IA anymore but do not gain any IA when HRE state converts from Catholic to Protestant faith. Now I notice the wiki states from 1.7 on no IA gain, pitty. Even when using Emperor action "Enforce religious unity" I actually lose 1 point IA which is weird on top of -25 relation hit which makes this action useless - I think there should be +10 IA gain instead.

Anyway, my question: what is actually the One True Faith of the HRE and how is it determined? The religion of the emperor? The majority religion of empire members counted by votes? The majority of HRE base tax? Or is locked to Catholic? Can that be found anywhere in game?

It's decided by League Wars if you have the DLC that unlocks those. Without that DLC, I believe it's the majority religion.

In 1.7 it's religion of the emperor, but mind that different relligion electors won't vote for You, so it's quite often also a relligion of majority of electors.

It is Catholic until the wars of religion start, then it is determined by who wins the war.

Edit: yeah, assuming you have the DLC

It is Catholic until the wars of religion start, then it is determined by who wins the war.

And who finishes it as a victor or whether it ends in a stalemate. IMO, stalemate is the worst scenario because of elector religious background difference (& possibility of all-Catholic electorate, essentially ensuring unfair status quo).

I won the war for Protestants as Milan, but later the Catholics were heavily beefed up by departures from my league and to the opposite (including myself) and they managed to get a religious peace.

So it's decided when either side deals the decisive blow and it is not contested or when religious peace is ensured (which happens often as the AI, even when winning, will often peace out by just taking provinces or other stuff, without using the "enforce religion" war demand).
