Why does the unification of civilization usually lead to prosperity and stability?

It usally causes that because they have 2 diffrent beliefs. Each civilization is diffrent in many ways. If they want to conjoin civilizations, than it will have to be 2 great groups because it is very hard to live with people that worship diffrent, just do diffrent things. There will be hate in the civilizations. Think of it like America. In America we have many diffrent cilvilizations in one country. We have hate in our country. African Americans and whites have tons of disagreements. Also so do Mexicans and whites. Living with diffrent people can be hard. But some people can deal with it in many diffrent ways.
