How does Jerusalem cause conflict between Muslims and Christians?

It is the Holy city for both religions. When the Muslims took over Jerusalem, the Christians viewed it as their obligation to re-take it, which is the main reason for the Crusades.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
