Some examples are: Indus Valley Civilization, Ancient Egypt and Mesopotamia.
Mesopotamian civilization developed in the valley of the Tigris and Euphrates rivers and is considered the cradle of Western culture.
From those people come astronomical calculations, writing, the first code, city-states, and more.
Ancient Egyptian society had a very efficient but unfair form of organization, ensuring its functioning and expansion. This society was hierarchical, that is, each segment had certain functions and powers, with the least empowered groups having to obey who was above.
The Indus civilization, one of the first great civilizations in history, was in Punjab and was discovered in the second half of the 19th century. In the 1920s, a series of tombs were discovered that led to the excavation of two ruined cities.
