Rivers were attractive locations for the first civilizations because they provided a steady supply of drinking water and made the land fertile for growing crops. Moreover, goods and people could be transported easily, and the people in these civilizations could fish and hunt the animals that came to drink water.

Which civilization flourished along the river?

The first great civilizations, such as those in Mesopotamia, Harappa and Ancient Egypt, all grew up in river valleys. Mesopotamia civilization flourished near Tigris River and civilization of Egypt flourished near river Nile.

Why did ancient civilization flourish?

The earliest civilizations developed between 4000 and 3000 BCE, when the rise of agriculture and trade allowed people to have surplus food and economic stability. Many people no longer had to practice farming, allowing a diverse array of professions and interests to flourish in a relatively confined area.
