The conflict between Palestinian Arabs and Jews is a modern phenomenon, which began around the turn of the 20th century. Although these two groups have different religions (Palestinians include Muslims, Christians and Druze), religious differences are not the cause of the conflict. It is essentially a struggle over land. Until 1948, the area that both groups claimed was known internationally as Palestine. But following the war of 1948-49, this land was divided into three parts: the state of Israel, the West Bank (of the Jordan River) and the Gaza Strip.

This is a small area: approximately 10,000 square miles, or about the size of the state of Maryland. The competing claims are not reconcilable if one group exercises exclusive political control over the total
territory.

Jewish claims to this land are based on the biblical promise to Abraham and his descendants, on the fact that this was the historical site of the Jewish kingdom of Israel (which was destroyed by the Roman Empire), and on Jews' need for a haven from European anti-Semitism.Palestinian Arabs' claims to the land are based on continuous residence in the country for hundreds of years and the fact that they represented the demographic majority. They reject the notion that a biblical-era kingdom constitutes the basis for a valid modern claim. If Arabs engage the biblical argument at all, they maintain that since Abraham's son Ishmael is the forefather of the Arabs, then God's promise of the land to the children of Abraham includes Arabs as well. They do not believe that they should forfeit their land to compensate Jews for Europe's crimes against them.
