This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.

To change this template's initial visibility, the |state= parameter may be used:

• {{Historical Italian political parties|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
• {{Historical Italian political parties|state=expanded}} will show the template expanded, i.e. fully visible.

This template includes defunct political parties having elected at least one MP or MEP with their own logo or having had a parliamentary group in the Chamber of Deputies or in the Senate.
