Provide 3 details on how civilizations develop

Any specific 3 details? I will give you some 3 details I can think of now

1) Civilisations often develop writing, which helps them organise, this was the case In Mesopotamia, China and Mayans

2) Civilizations develop a hierarchical structure which also helps them organize (before civilizations the groups often have less hierarchical structure).

3) Civilizations are possible if agriculture produces food surplus - then some people can devote their time to other activities and this contributes to the development of societies
