Physical geography had a major influence on the development of Greek culture. The mountainous terrain of Greece made it difficult to unite the various city-states, leading to a decentralized political system. This decentralized system allowed for the development of a variety of cultures and customs, which were often based on the local geography. The rugged terrain also encouraged the development of maritime trade, which allowed the Greeks to spread their culture and ideas throughout the Mediterranean region. The Mediterranean climate also allowed for the growth of olives and grapes, which were important to the Greek diet and economy. Finally, the many islands of Greece provided a safe haven for the development of democracy and philosophy.
