Peoples migrate because of many reasons. Here is a summary of migration catalysts, it includes the major ones common to many peoples:
1. Climate. Changes in climate such as cold temperature changes may encourage a people to move to a warmer climate. This holds true for the reverse. Also a climate change reducing rainfall may force a people to seek more rain in order to grow their crops better.
2. Overuse of soil. Some ancient peoples may not have been aware of the practice of fallowing pieces of farmland. Not doing so wears out the richness of the soil and thus the population moves on to find fresh farmland.
3. Animal changes. A people who base their society on hunting wild game may be forced to migrate if the game they hunt has dropped in population or has "died out" to such a degree that the hunters must move on to find more game to hunt. Animal changes can result from disease, climate or over hunting.
4. Political changes. A people may find that tribes of new peoples are overwhelming the land they have dowelled in. This new people may be belligerent and cause danger to the original settlers. Thus the original people may chose to move on away from the new comers.
5. Government Political Changes. In more sophisticated societies are sensitive
to new governments that are hostile to them. In ancient societies, an invasion by another civilization, will change the "political power" structure. This change may force a people to move on.
5a. In more modern times a political change such as the expansion of the Soviet Union after WW2, may force parts of the now subjective population to seek political asylum.

What led to the great migration of 1629-1640?
It was the migration of settlers (mostly Puritans) to New England.
Who led great migration of 1843?
The Trail, also known as the "Great Migration" began in 1843. 1000 pioneers assembled with 120 wagons and 5000 head of livestock left Independence Missouri for a greater life out west. This was the largest peacetime migration in the history of the world.
What type of diffusion is migration?
Relocation diffusion.
Technology language and writing were widely spread due to?
migration
What is Regional Migration?
Regional migration is the process of the horizontal movement of gas or oil through a reservoir. This happens because of the artificial pressure differences created by gas or oil withdraw at well sites.
Why are all enzymes catalysts but not all catalysts are enzymes?
but all catalysts aren't enzymes...
How are catalysts and enzyme related?
Enzymes are catalysts.
How enzymes and catalysts related?
Enzymes are catalysts.
How many types of catalyst are there?
There are mainly two types of catalysts: homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase. Homogeneous catalysts are usually dissolved in the same solvent as the reactants, while heterogeneous catalysts are typically solid catalysts in contact with the reactants.
Are catalysts a example of enzymes?
enzymes are biological catalysts
What has the author Kazuo Hata written?
Kazuo Hata has written: 'New hydrogenating catalysts' -- subject(s): Metal catalysts 'Urushibara catalysts' -- subject(s): Metal catalysts
Is it proteins and catalysts that speed up the rate of a reaction?
Catalysts
Do catalysts form salt?
Of course not, catalysts doesn't react.
Enzymes are catalysts. How do enzymes increase the reaction rate?
Enzymes are natural catalysts, these natural catalysts speed up reactions.
Why are catalysts essential to biochemical reactions that occur in living organism What do you call these special biological catalysts?
Without catalysts many chemical reactions cannot occur; biological catalysts are called enzymes.
What function do catalysts perform in chemical?
catalysts speed up a reaction
What is the truth about catalysts?
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
