Suleiman Nabulsi (born 1908) was a Jordanian political activist. He was appointed as Jordan's ambassador to Britain in 1953. His experience in Britain turned him into a staunch Arab nationalist and anti-Zionist, and he resigned 5 months later from the post. Returning to Jordan in 1954, his nationalism alienated him from King Hussein who had him exiled from the capital Amman to a provincial town. At this time, his supporters established the National Socialist Party (NSP) and Nabulsi was elected its leader. The Party aimed at reducing the grip of the Palace on politics, and establishing greater relations with anti-imperialist Arab states at the expense of Britain. The 1950s witnessed the rise of Nasserism, a socialist Arab nationalist political ideology based on the thinking of Egyptian President Gamal Abdel Nasser. Jordan captured the West Bank during the 1948 Arab–Israeli War, and it annexed the territory in 1950. Jordan's population now was two-thirds Palestinian who outnumbered Transjordanians, the Palestinians had identified with Nasser more than Hussein. Nasser's Egyptian–Czechoslovak arms deal in September 1955 and the July 1956 nationalization of the Suez Canal had greatly added to his popularity across the Arab World.
