Why did western Europe developed more then Asia, Africa and the Americas?

and till the Renaissance it was Asia that was more developed.

but some time in history the western world got the uppr hand.

and why never Africa and the Americas never evolved from the primitive state. i mean in the of the scientific/practical technologic point of view. couse in the spiritual world point of view they are far more advanced. why did the western world developed and evolved in the world of technology far more other parts of the world?

This is a question I discuss in my world history classes.

The simple answer is continuous warfare between the emerging states of Europe - - each trying to gain a technology advantage.

Leonardo Da Vinci's genius was applied to war in the early 1500s. Other men of genius put their talents to military advances rather than advances in the 'quieter' arts.

I did not think Jared Diamond's book was nearly as

good as "The Pursuit of Power" by William H. McNeill 1982

regarding this topic.

Military power and transport to project that power have been the keys. That is where western Europe led the way. Power leads to wealth which pays for more power in the form of military expenditure.

Japan caught up VERY quickly after 1870 - and WWII in the Pacific was one result.

China is becoming wealthy again - - AND they have learned to use modern military power.

Western Europe / America will not be in the lead much

longer.

Hopefully, compromise and peaceful coexistence will prevail.

western world are famous in cutting off their King heads when things go wrong while the eastern world are famous in cutting the ppls head when their Kings see something wrong to their power over the ppl

I suggest reading "Guns, Germ, and Steels" by Jared Diamond.

I agree with the guy above. That book does an excellent job of discussing your question in depth.
