How to trigger the religious league war

[byebytoad]

I'm the Emperor as Piedmont-Sardinia, and the evangelical union even occurred.
I don't seem to have the religious supremacy casus belli against the Protestant league leader, so what can I do?
Just wait?
Is it sure that the Protestant league leader will declare war on me and within what time frame will that occur?

Only the Protestant Leader can declare war. Only thing you can do as Emperor is to appear weaker than the Evangelical Union.

How long do they have to declare? Is there any way I can push some kingdom to join the enemy side in order to give them better chances and make more likely to trigger the conflict?

After 50 years the leagues have formed the Peace of Westphalia can occur if they didn't declare a war. Make sure you are at peace around that time and that you don't have a truce with any of the protestant electors.

The most reliable way to push someone into the enemy camp is to be their rival, they tend to like joining against you. If you have any big Catholic/heathen powers outside the HRE, try rivaling them and they most likely will join the protestants. If you are confident you can win the war alone you can also try getting rid of your allies to appear weaker, though they still may remain part of you side of the league if they've joined.

It's actually 30 years to happen, then there is quite a high chance this event happens, but only when the conditions you mentioned are fullfilled https://eu4.paradoxwikis.com/Religious_league_events#The_Diet_of_.24CAPITAL_CITY.24

So unless you want to experience the war itself you can just wait for that event.

Right, it's 30. I remembered 50 because of the 1625 date requirement and because leagues usually come around in my games around the 1560-70s.
