Yes, but it's interesting to note the difference between when a large region is united through conquest by locals, or an outside power further away. Italy, in comparison to the above two examples, was united by the local Romans. (Though of course, "local" is incredibly relative. The difference between northern and southern Italy has been vast even unto modernity, never mind during antiquity.)
Now, I'm not sure what the difference of living under Maurya vs. Mughal vs. British rule was for its inhabitants, these are widely different polities from completely different time periods, but it's still a distinction. Though I suppose more of a retroactive one imposed by our modern bias, when we can point at India, Italy, and Germany and say, "ah, that patch of land is naturally meant to be united by someone."
