Franz's prediction wasn't wrong; once the Greeks had captured Prince Ludwig, the prospective king, they didn't know what to do with him.
There was also a split within the Rebel Army, with one faction advocating the establishment of a Republic, attempting to break free from Austrian control over Greece.
The other faction argued for the enthronement of Ludwig to succeed the throne, with the reasoning that Prince Ludwig was the legitimate heir.
Before Austria had the chance to send troops to intervene, the Republicans and the monarchists were about to come to blows. Mostly capitalists, the Republicans also had a bunch of sophomore teenagers, while the monarchists were naturally the Nobility.
As for the numerous peasants and workers, they were mere spectators. This coup had nothing to do with them, and there was no need for them to take a stand.
