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.
