The Jews and Palestinians were fighting over land. For centuries, the entire area was ruled by the Ottoman Empire (today Turkey). After World War I, the area that is now Israel was taken over by Britain. The British favored the idea of establishing a Jewish state in the middle east, since historically that was their homeland, and since there was so much anti-Semitism in Europe. Between WWI and WWII thousands of Jews moved to Israel (then called Palestine) and established communities, farms, businesses, etc. They were still a fairly small percentage of the population, so the local Muslim population was not too upset, but as the number of Jews increased, tensions started to arise. After WWII, the United Nations began discussing the creation of an independent Jewish state. Thousands more Jews, mainly Holocaust survivors, moved to Israel. The United Nations proposed to divide the territory into 2 separate countries in 1948, Israel and Palestine. The Palestinians and surrounding Arab countries rejected the UN plan as unfair because it gave too much land to the Jews. The Jews declared independence anyway, and the surrounding Arab countries declared war on Israel. It is important to note that the main source of the Arabs' anger was not religion, but rather the legacy of European imperialism. European nations such as Britain and France had been controlling the Middle East for years, and these countries saw the creation of Israel as another imperialistic act. From the Jewish point of view, they were tired of 2,000 years of anti-Semitism, persecutions, pogroms, and being kicked out of other countries, so they really wanted their own nation. Of course, control of the "Holy Land" of Jerusalem was also part of it.
