Distance between city-states, clothing, trade, and democracy were amongst some of things that were influenced by the geography of Ancient Greece. The Greek lived in a Mediterranean climate. Winters were mild and wet, and they were able to grow grapes and olives. Summers were warm and dry. Grapes and olives were one of the few plants that could survive droughts. Mountains cover Seventy-five percent of Greece. The land was difficult to cultivate and the sea surrounded Greece. This made trade extremely easy because the Greeks could get what they could not grow. They were also able to bring back innovative ideas from other cultures that they traded with. Because mountains cut off the Greek, this led to the formation of city-states. There was limited interaction and unity of the city-states, which ultimately created river lies amongst them. Such physical barriers prevented a unified Greece. The sea became a vital part of the Greek society. There were hundreds of bays, skilled sailors, and trade of olive oil, wine, and marble for grains, metals, and ideas, technology, and philosophies was common trade items. The Greeks were able adopt the Phoenician alphabet, which later become the basis for all western alphabets. It also promoted democracy. Although the sea encouraged trade, the mountainous terrain enabled absolute rulers to gain power, ultimately leading to the demise of the Ancient Greek democracy and thus creating war mongers.
