Yup this is exactly it, I just totally blanked out on the show name so I couldn't find the reading list and such 😅 And it is the Siemann book indeed

I actually found it and it's been translated now - I couldn't find it at first because I forgot it wasn't just about the Congress, it's a book of around 1000 pages on Metternich, and ofc includes what happened at the Congress.

I remember listening to a podcast that had a really great book in their reading recommendations, but it's only in German and not translated - at least not when I checked last

What would be some good books about the Congress of Vienna? With the roles/POV of Metternich, Talleyrand, etc.
