Is there any way to check which faction is enjoying the 'Golden era'?

[byebytoad]

I know you get a notification when a faction begins their golden era, but obviously I forgot eventually who they are.
Is there a way to check which faction is experiencing their golden era , when this one expires and which factions already had one ?

Not sure where you can get a list, but you can check specific countries by looking at their morale in the ledger, since the golden era modifier increases morale of armies.

You can check a province of someone you want to know and look at "Goods Produced". If they have a golden era, it should say something like "Golden Era +10%".
