Sparta, for instance, satisfied the land-hunger of her citizens by attacking and conquering her nearest Greek neighbors. The consequence was that Sparta only obtained her additional lands at the cost of obstinate and repeated wars with neighbouring peoples of her own calibre. In order to meet this situation Spartan statesmen were compelled to militarize Spartan life from top to bottom, which they did by re-invigorating and adapting certain primitive social institutions, common to a number of Greek communities, at a moment when, at Sparta as elsewhere, these institutions were on the point of disappearance.

Athens reacted to the population problem in a different way again. She specialized her agricultural production for export, started manufactures also for export, and then developed her political institutions so as to give a fair share of political power to the new classes which had been called into being by these economic innovations. In other words, Athenian statesmen averted a social revolution by successfully carrying through an economic and political revolution; and, discovering this solution of the common problem in so far as it affected themselves, they incidentally opened up a new avenue of advance for the whole of the Hellenic Society.
