Ok, i found some interesting material in matter of italian music in the history.
In 1860, ruler Cavour (kingdom of Italy), this is the music:
In 1930, ruler Mussolini (fascism), this is the music:
In 1960, ruler Andreotti (Italian Republic), this is the music:
It is folk music, no copyright, and everybody in Italy understands the historical time and meaning of these musics.
The problem is the music in medieval age.
There was no Italy at that time, and as i previously wrote, medieval Italy is represented in game by Lombard People, with a flag of Venice, a ruler of Florence and a music of Naples.
Maybe players of the rest of the world can say "That's italian stuff, that's OK".
I have to ask to you players of the rest of the world: is it ok for you the music of Tarantella, related to Lorenzo of Florence?
If yes, let it be.
If no, i found on youtube some alternatives:
An opera of Giuseppe Verdi, titled "The Battle of Legnano", we can extract something from it...
For example from 2:48 of this one:
Or a music of renaissance related to Lorenzo de' Medici.
From 34:41 of this one:
If you instead like a music related to Venice, well... let me know.
