The flag of Jordan is based on the flag of the Arab Revolt against the Ottoman Empire during World War I. It has black, white and green stripes connected by a red triangle. The colors stand for the Abbasid, Umayyad and Fatimid Caliphates, and the red triangle is for the Hashemite dynasty and the Arab Revolt. The seven pointed star stands for the seven verses of the first surah in the Qur'an, and also stands for the unity of the Arab peoples.
