Now that you have closed the gap to your ally Ludwig der Listige in Moravaria you basically brought peace to the lands - all the brothers have been defeated or are simply not strong enough anymore to pose a threat. Time for a little celebration, don't you think?
- Build a cultural building or decoration of the High Middle Ages or research a technology that unlocks a cultural building.
Good, your people are celebrating your victory and the newfound peace. You did very well!
