A strong fortified settlement is not the push factor in migration
Explanation:
There is difference between a push and a pull factor. Push factor is the cause which forces a person to leave the country in search of better living. Depletion of resources, war and famine are some of the push factors.
Pull factors are the aspects which pulls or attracts the migrated people into the land due to the abundance of natural resources, better living conditions, employment opportunities, educational opportunities and practicing religious freedom. These are various pull factors which allures the people for migration. African Americans migrated from the southern states to union in search of better living conditions and industrialization which opened huge employment opportunities.
The prehistoric era predates writing. Human progress included primitive tools and weapons, clothing, fire, cave art and burial of the dead. During the Old Stone Age, human beings were learning, but they were learning slowly. Then around 10,000 years ago progress began to speed up, with developments like agriculture, the domestication of animals, the creation of permanent villages and cities, etc. Writing began to appear around 5,000 years ago (around 3,000 BC) and that may be the beginning of what we call history, since we begin to know what people were thinking as well as what they were doing.
