This is complicated! Depends on what you mean by 'owned' really and what part of the 19 century. Even now Italy is possessed of states within itself. eg Vatican City/San Moreno (I think). But first you have Napoleon carving it up and giving it to his siblings. Then when he foundered Austria interfering, then. independence under Garribaldi. I'd check out his history on Wikkipedia or any site he has, Regards.
