:::::There are many other historians besides Signor Casula, who sounds a bit of a maverick (I've never heard mainstream historians talking of "perfect" and "imperfect" states; and surely we can all see, even if Casula can't, that Sardinia was no more "perfect" after 1720 than it was before - it was still subject to an outside ruler, the only difference being that this outside ruler, having no other kingly titles, decided to transfer the name "Kingdom of Sardinia" to the whole of his domains).
