Answer:
Judaism, Christianity, and Islam are in constant conflict over the land in the Middle East.
Explanation:
The Middle East is a region that is important for many reasons, and one of them is religious importance. This area is actually the birthplace of three major religions, the so-called Abrahamic religions. The three religions that emrged in this region are Judaism, Christianity, and Islam, in that order.
Judaism came first, and what is now Israel is considered as the holy land for this religion. Despite many attempts to forcefully removing the Jews from this area, some of them still managed to survive there and many more came back in the last century to reclaim what they consider as historically theirs.
Christianity emerged from Judaism. What is now Israel is also holy to it, and especially the city of Jerusalem. The claim of the Christians for this region is that their religion emerged there and its holy places have to be in their hands and no one else.
Islam came last, emerging from Christianity. Soon it became the dominant religion in the region through conquest and assimilation. It has been dominant in the area for over a milennium, so the claim is that it is historically theirs and since they managed to conquer the place it belongs to them.
