Passage: In 1944, Arafat enrolled in the University of King Fuad I and graduated in 1950. At university, he engaged Jews in discussion and read publications by Theodor Herzl and other prominent Zionists. By 1946 he was an Arab nationalist and began procuring weapons to be smuggled into the former British Mandate of Palestine, for use by irregulars in the Arab Higher Committee and the Army of the Holy War militias.During the 1948 Arab–Israeli War, Arafat left the University and, along with other Arabs, sought to enter Palestine to join Arab forces fighting against Israeli troops and the creation of the state of Israel. However, instead of joining the ranks of the Palestinian fedayeen, Arafat fought alongside the Muslim Brotherhood, although he did not join the organization. He took part in combat in the Gaza area (which was the main battleground of Egyptian forces during the conflict). In early 1949, the war was winding down in Israel's favor, and Arafat returned to Cairo from a lack of logistical support.After returning to the University, Arafat studied civil engineering and served as president of the General Union of Palestinian Students (GUPS) from 1952 to 1956. During his first year as president of the union, the University was renamed Cairo University after a coup was carried out by the Free Officers Movement overthrowing King Farouk I. By that time, Arafat had graduated with a bachelor's degree in civil engineering and was called to duty to fight with Egyptian forces during the Suez Crisis; however, he never actually fought. Later that year, at a conference in Prague, he donned a solid white keffiyeh–different from the fishnet-patterned one he adopted later in Kuwait, which was to become his emblem.
