I'm a big fan of the Italian States, so I have some suggestions about the flag.
The new flag is awesome, I like it realy much, but because I am a republican in real life, I like playing with a republic state.
But when I rebel, my republican flag is still the same.
This is quite wrong because the flag is a sign of absolute monarchy.
That's why I made a kind of prototype of the Italian States republic flag:
This is based on the warflag of the early Italian Republic in the 18th century.
I Held the tricoulor and the laurel wreath as a sign of being a republic.
The 'RR' (normaly) stands for 'Republica Romana', pointing at the fact that it is a republic.
While there was no Italian revolution before Napoleon, I thought they would look to their great ancestors: the Romans, and this is what I came up with.
For the warflag I chose the real historical warflag from the Italian Republic:
The text reads 'Roman civil guards'.
EDIT:
I found a naval flag!
I made one from the earliest naval jack I could find.
Remember that all this flags are for the republic version!
