By 1957, pan-Arabism was the dominant ideology of the Arab world, and the average Arab citizen considered Nasser his undisputed leader. Historian Adeed Dawisha credited Nasser's status to his "charisma, bolstered by his perceived victory in the Suez Crisis". The Cairo-based Voice of the Arabs radio station spread Nasser's ideas of united Arab action throughout the Arabic-speaking world and historian Eugene Rogan wrote, "Nasser conquered the Arab world by radio." Lebanese sympathizers of Nasser and the Egyptian embassy in Beirut—the press center of the Arab world—bought out Lebanese media outlets to further disseminate Nasser's ideals. Nasser also enjoyed the support of Arab nationalist organizations, both civilian and paramilitary, throughout the region. His followers were numerous and well-funded, but lacked any permanent structure and organization. They called themselves "Nasserites", despite Nasser's objection to the label (he preferred the term "Arab nationalists").
