The other day, I posted on that the Athenian occupation of Sicily wouldn't be possible, due to the relatively small numbers of Athenian citizenry, and the exclusionary hereditary nature of Greek polis citizenship. So I was wondering which select Athenian politicians could have instigated internal social reforms that would have led to the civil enfranchisement of Metics and subordinate allied polis's within the league. What series of political processes would be needed to have led to the ultimate amalgamation that would transform the allied city-states into a perpetual federation that could go as far to subjugate the remainder of Hellas, and later assert control of the colonies across the Mediterranean as part of a imperialistic protection racket?
