In what ways did the civilizations interact with and influence each other?

The reality of human interactions is that we fear and avoid what we don’t understand.  Most conscious thought about culture is about differences: “we” have this way of doing things, “they” do something else.  This affects all interactions in a fundamental way.  Similar cultures will mix more, trade more, share more than distant cultures.

But culture is more than a way of being – it affects the way people interact in and behave very deep ways.  Turchin’s theory of civilization says that Asibiya – the ability for group action – builds up exactly on the borders between cultures.  This is because the definition of “us” becomes very clear when contrasted to a very different “them”.  It’s a nasty fact of humanity that people can show great altruism and kindness to others, yet on an everyday level it is often nepotism – aggression towards people out of your group – that rules.  The origin of states arises from small tribes lies that form strong bonds –  which is precisely what Asibiya is designed to explain.

Culture and religion are integrally related, and religion is an aspect of culture that kingdoms have some reasonable control over.  Although switching between Christianity and Muslim faiths has been a long and painful process for many nations, religions can splinter off and yet remain fundamentally the same thing to the peasantry.  Protestantism appeared mostly as a response to Catholic domination and attempts to influence politics. Although almost the same faith, the differences create a strong “us and them” feeling in people – at least the nobles – that allows wars to be justified and alliances forged.  Yet both are “us” when compared to their more different neighbours – Muslims, or the Sikhs, or the Jews.

Differences in religion and culture in general control what is acceptable and unacceptable in war, whether the enemy is just an ally with the wrong king, or an inhuman devil.  What do the populace think of the king burning an enemy city?  If there is little shared culture with the city then people will be content, possibly even happy to see the influx of “free” goods and slaves.  But if people know people of the persecuted culture, trade there, visit there on pilgrimage or have a religious empathy for them, then they will object, strongly.  In ancient times, warfare often resulted in the burning of cities and the taking of slaves.  Conversely, during the late middle ages (and most civil wars) the European nobility fight each other – and people do die – but cities go on much as they always had because nobody would benefit from harming the people.

c) they were beaten and fired from their jobs.

so they can differentiate themselves from others as they saw themselves as the superior race. the star was basically a symbol that meant you are a less of a person than i am because of my race. the star was also degrading for those who had to wear it because they were aware of this and the nazis used the notion to make them feel less like a person.
