In 1948,the United Nations divided the land Palestine between an Arab and Jews.United Nations made Palestine and Israel,two independent nations,side by side,in 1948.So we can say that Israel was created by this action of land in 1948.
The modern conflict between Jews and Arabs dates back to the 1910s,when both groups laid claim to the British controlled territory.
The Jews were Zionists,recent emigrants from Europe and Russia who came to the ancient homeland of the Jews to establish a Jewish national state.
The native Palestinian Arabs sought to stem Jewish immigration and set up an Islamic Muslim Palestinian non secular state.
In 1929,Arabs and Jews openly fought in Palestine,and Britain attempted to limit Jewish immigration as a means of appeasing the Arabs.As a result of the Holocaust in Europe,many Jews illegally entered Palestine during World War 2.
