How did the greek government transition to the development of democracy

When democracy began in Greece, only the inhabitants of the Athenian mother and father could participate, they had to be men and have completed their military service.

After nearly 700 years of this regime, during the war against the Persians, Solon, a politician who ruled Athens, reformed society. All the population participated in the war effort and after the victory, the concept of democracy was redefined, that is, a government made up of Athenian citizens, rich or poor, aristocrats or peasants.

By the time of the Uruk period (4100–2900 BC), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers.

China’s main point of transportation for their trade was their rivers and canals, which also strengthened their economy and kept them on a steady rise.

Hope this helps!
