If you do not like to read all of it, in a nutshell, the Habsburg Monarchy was overwhelmingly defeated by the Mihai Viteazul's (Michael the Brave's) Romanians and the Ottoman Empire.
At the Peace Treaty, they lost almost all Royal Hungary and Croatia and had to pay reparations that almost bankrupted them. See map.
Rudolf II is mentally ill, officially declared incompetent to rule and Matthias has assumed the Crowns of the remaining Habsburg Realms. However, he is not Emperor yet. Elections are to be held.
Matthias has less army to impress the other German states, almost no money to bribe the electors, less land and less influence.
Since my knowledge of the Holy Roman Empire is way less than that of many of you, I ask for your help.
Who do you think would get elected Holy Roman Emperor in these conditions?
