Say Albrecht and Isabella Clara, have progeny and he succeeds Mathias as HRE. What are the potential consequences on
- thirty yrs war/denominational conflict within the Empire
- the situation in the Low countries? Can they be re-captured or is the 12 yrs truce renewed
- Imperial French relations, still the same, different?
- Anglo-imperial relations? If no Spanish match would a Burgundian/imperial match be an alternative?
- other thoughts you might have?
