Why do the conflicts between Israelis and Palestinians exist? What were the reasons for this and why are they still going on in time? At the outset, it must be remembered that in the last few years since the Middle East was negotiated at Versailles in 1919 and the United Nations sharing of Palestine in 1947, the world has observed the incessant conflicts between Israelis and Palestinians without a complete conception of the problem . For many, it is an eternal struggle for land, for others a religious necessity. To the extent that the reader follows the development of the facts here narrated, he may have a better understanding of the events that have arisen in present-day history, from a historical, political and legal point of view in Palestine. In general terms, in order to arrive at the answers, it is necessary to combine the historical factor with the legal factor so that the events can have a logical linear basis since its beginning in the twentieth century with an analysis of the regulations made by the International Law on these facts.
