Causes of the 1948 Palestinian expulsion and flight

During the 1948 Palestine war in which the State of Israel was established, around 700,000 Palestinian Arabs, or 85% of the total population of the territory Israel captured, were expelled or fled from their homes. The causes of this mass displacement have been a matter of dispute, though today most scholars consider that the majority of Palestinians were directly expelled or else fled due to fear.

Causes of the exodus include direct expulsions by Israeli forces, destruction of Arab villages, psychological warfare including terrorism, dozens of massacres which caused many to flee out of fear, such as the widely publicized Deir Yassin massacre, crop burning, typhoid epidemics in some areas caused by Israeli well-poisoning, and the collapse of Palestinian leadership including the demoralizing impact of wealthier classes fleeing. Many historians consider that the events of 1948 were an instance of ethnic cleansing.
