How did the geography of Greece affect Greek history in terms of politics, military developments, and the economy?

The geography affected Greece in that much of the maneuvering and fighting relied on the sea and naval power, as the Greek world was spread around the Mediterranean Sea littoral.

Explanation:

In addition, the mild climate allowed for many Greeks to become traders and pirates, which made ancient Greek society cosmopolitan. Ancient Greece was made of hundreds of small islands and mainland regions that spanned across the Aegean, Mediterranean and Ionian seas.

The proximity of the sea also shaped the Greek economy. Because the sea was so easily accessible and because overland trade was difficult, the Greek economy came to be based on maritime trade.
