What if the Premyslids were elected to the Holy Roman Empire? what would be it's consequences on Bohemia? would it Germanize?
What would be it's consequences on Poland and Hungary?
What would be it's consequences on Poland and Hungary?
Why they would be elected on first place?
You need to be an influent and powerful family for making the electors considering choosing you : it's generally a germanic family because they're interested first on diplomatic repercussions.
So, you'll need the Premyslid to not being king of Poland in first place, in order to have a more westwards focus than OTL.
Furthermore, to have a noticable impact, you'll need to have more than ONE Premyslid emperor, and find why the german princes would see the bohemian duke the better alternative than Staufen.
Finally, as you maybe noticed, the dynastic principle, while modified by the elective fashion, was still present in HRE. Many new dynasties were related to Salian one.
You'll probably need the Premyslid to have a more important matrimonial policy with Salian or Staufen.
Maybe. Ottokar had ties with Staufen dynasty, and was enough powerful within the HRE to be considered.
Actually, he tried to became Rex Romanorum OTL, but Rodolf von Habsburg was preferred, and eventually he lost many German possessions.
If you manage to kill Rodolf von Habsburg soon before or after the election, or having Ottokar winning the war, maybe it could work (while, in the latter case, the lack of legitimity would be a serious obstacle, and it could be likely seen more as a pretender or an anti-rex than a real emperor).
The main issue was Rodolf was supported against Ottokar precisely because Ottokar was too powerful, too quickly. A less harsh treaty on Hungary could resolve some thing...But Ottokar will need to show the german princes that he won't be a threat to their autonomy and/or independence.
