Palestinian refugees are the largest and longest lasting refugee group in the world. Palestinians were first made refugees in 1948 when Zionist Jews drove 750,000 from their homes in what is called the Nakba, or catastrophe. When Israel waged the 1967 war and occupied the West Bank and Gaza, another 350,000 were forced into exile. From these two groups of people stem today’s Palestinian refugee population, which now has swelled to more than 7 million people. In fact, Palestinians make up the world’s largest and longest-lasting refugee population. A full 40 percent of the world’s refugees are Palestinians; 74 percent of the total Palestinian population is refugees as well. The United Nations Works and Relief Agency was created to deal with the Palestinians who were made refugees after the UN Partition of Palestine and the 1948 Nakba.
