In the primitive democratic tradition, there was a monarch who did it for two people.

The material foundation determines the superstructure, and it is the difference of economic civilization between the two places that determines the difference of political civilization between the East and the West. In the era of natural economy, the economic model is bound to be influenced by natural conditions.

Chinese civilization originated in the "river basins" of the Yellow River and the Yangtze River, with farming as the main mode of economic production. This economic model requires social members to unite, obey and work together, thus forming an efficient and unified monarchy system that emphasizes obedience from top to bottom.

Greek civilization originated in the Mediterranean region. The Mediterranean climate has poor hydrothermal conditions and rugged and fertile terrain, which makes it impossible to develop farming. The limited carrying capacity of agriculture to population forces a part of surplus social labor to engage in secondary and tertiary industries. Close to the ocean, members of society are distributed on different islands, which is helpful to promote the development of primitive industry and commerce. This economic model requires members of society to negotiate and compete, thus forming a democratic system that emphasizes freedom and equality.

Of course, Greek democracy is not a real democracy. Which democracy do you see with slaves? The economic foundation determines the superstructure, and the emergence of a real democratic system needs a considerable degree of socialized industrial production and modern commodity economy as the foundation, while ancient Greece obviously did not have such economic conditions under the condition of underdeveloped agriculture. Democracy in ancient Greece was only a premature baby under specific historical and natural conditions, and its contribution to social development was limited. Later, in the Roman period, with the continuous development of agriculture, the primitive democratic system could not meet the needs of social development. At this time, it is also a historical necessity for Rome to change its democratic system and establish an empire.
