Could we say that the 80s was really an important decade for the italian organized crime groups ?

You had the second sicilian mafia war (more than 1000 deaths) and the second ndrangheta war (more than 600 deaths).

Also, it seem that many new organizations were created during this decade.
You got the Stidda that was created in Sicily and went against the sicilian mafia.
You had the Sacra Corona Unita, that came out of the ndrangheta (I think)
And not least, you had the Società foggiana who split up from the Sacra Corona Unita.

Italy was probably a hot mess during this decade. Many politics between gangsters.
