So, just for kicks, I saved once Hungary was created and loaded up as them - and lo and behold! I got the Austrians to accept stats quo peace with me, and they declared war again a months later. This time, I defeated them and took several of their provinces. I only won because the Serbian/Croatian revolt happened mid-war, so the Austrians had to deal with a loss of troops and a bunch of revolters. Not only did they eventually offer peace and recognize my independence, but the revolters spawned Croatia, which I ceded provinces to and satellited.
Anyone else tried their hand at Hungary?
