Is there any logic to war leader changes?

[Laurwin]

-I'm muscovy I dow kazan horde with holy war CB. Kazan horde is a huge blob anyway, I though it would be no way possible for war leader to change, I though I would be ok though because I have better tech.

-LOL looks like I thought wrong, Kazan is allied to Timurid and zaphoridze (I think?)

-War leader changes to Timurid.

-Timurid calls everybody and their mothers into war now, including ottomans, including other horde allies.

-timurid stays war leader, thankfully

-Ottomans invade with their huge doomstacks through military access through POLAND OF ALL PLACES (I had alrady neutralized crimea in earlier wars)

-I bribe myself out of this diplomatic shenanigan, with peacing out through Timurid, war leader after I win some battles against Kaazan and timurid.

Next time Poland, I got my eye on you... :glare:

BTW it was not coalition war. It said, simply that Ottoman was defender in the war of Muscovite crusade against Kazan. It's just weird how these cascading alliances happen for some reason or the other. Is there any underlying logic into the mechanic (war leader change during war)

Was there a defender of the faith?

The war leader doesn't usually change if the defender is of decent size.

This table shows you whether WL can change or not, based on the CB used. That's the primary factor in whether it can change or not: http://www.eu4wiki.com/Cassus_belli#Summary

I guess, the conclusion is that youre basically screwed in most cases if you want to fight war without changing warleader lol (because only select few cbs disallow war leader change)

How can you see, who is the muslim defender of sunni/shiite? Is there something in ledger?

Does defender of faith give automatic alliance CB, when your religion is dowed with holy war cb?

Kazan looks big but isn't actually all that powerful. So it's perfectly reasonable that the Timurids became the war leader.

For the DotF look in the ledger in the religion screen, it shows who it is for every faith.
Being DotF doesn't give you a CB, it means you will be called to war if one of your brethren is attacked by heretics/heathens (no matter what the CB is). Should you refuse or lose the war, you lose the DotF status.
