Although the Ayyubid dynasty that he founded would only outlive him by 57 years, the legacy of Saladin within the Arab World continues to this day. With the rise of Arab nationalism in the 20th Century, particularly with regard to the Arab–Israeli conflict, Saladin's heroism and leadership gained a new significance. Saladin's recapture of Palestine from the European Crusaders is considered an inspiration for modern-day Arabs' opposition to Zionism. Moreover, the glory and comparative unity of the Arab World under Saladin was seen as the perfect symbol for the new unity sought by Arab nationalists, such as Gamal Abdel Nasser. For this reason, the Eagle of Saladin became the symbol of revolutionary Egypt, and was subsequently adopted by several other Arab states (the United Arab Republic, Iraq, Libya, the State of Palestine, and Yemen).
