Ancient Greece is the open source of western history, which lasted about 650 years (800 BC-65438 BC+046 BC). Located in southern Europe and the northeastern Mediterranean, including the southern Balkans, the west coast of Asia Minor and many small islands in the Aegean Sea. In the 5th and 6th centuries BC, especially after the Greek-Persian War, the economic life was highly prosperous, resulting in splendid Greek culture, which had a far-reaching impact on later generations. The ancient Greeks had profound attainments in philosophy, history, architecture, literature, drama, sculpture and many other aspects. After the destruction of ancient Greece, this cultural heritage was destructively continued by the ancient Romans, thus becoming the spiritual source of the whole western civilization. Ancient Rome usually refers to the civilization that rose in the middle of the Italian peninsula in the 10 century BC. After the Roman monarchy and the Roman Republic, it expanded into a huge Roman empire spanning Europe, Asia and Africa around the 10 century. By 395, the Roman Empire was divided into two parts. The Western Roman Empire perished in 476. The Eastern Roman Empire (Byzantine Empire) became a feudal country, and/kloc-0 was destroyed by the Ottoman Empire in 453.
