Innovations and technology were at the same level and culture was propagated and expanded easily among the different cities but they were by no means unified, look at the social and political structure of Athenas and compare it to the ones at Sparta, almost two different worlds, military technology, strategies and formation were different, heirs and inheritance had very different rules, arts were very different, even the view of life and understanding of the world was very different... they might have look similar as Phoenicians or other bronce age, early Iron Age tribes from the region, specially since through commerce and piracy there was a permanent exchange of products and ideas.
