The United Nations Relief for Palestine Refugees presents a challenging example of the world's response to a new and sudden human tragedy at a time when its sympathies had almost been drained away by recent appeals. The need for relief measures in the Middle East was created by the flight of at least 750,000 Arabs from their homes in Palestine during 1948. The problem was first brought to the attention of the United Nations by the late Count Folke Bemadotte and the Arab League in July of that year, and there was set in motion an ad hoc relief organization, the direct descendant of which is functioning at the present time. A brief survey of the operation to date provides a study in the manner in which international organizations, governmental and nongovernmental, have met human needs in an area seething with tension and tragedy.
