Rumi Jalāl ad-Dīn Muhammad Rūmī (Persian: جلال‌الدین محمد رومی‎ ‎ ), also known as Jalāl ad-Dīn Muhammad Balkhī (جلال‌الدین محمد بلخى ), Mevlânâ/Mawlānā (مولانا , "our master"), Mevlevî/Mawlawī (مولوی , "my master"), and more popularly simply as Rumi (30 September 1207 – 17 December 1273), was a 13th-century Persian Sunni Muslim poet, jurist, Islamic scholar, theologian, and Sufi mystic. Rumi's influence transcends national borders and ethnic divisions: Iranians, Tajiks, Turks, Greeks, Pashtuns, other Central Asian Muslims, and the Muslims of South Asia have greatly appreciated his spiritual legacy for the past seven centuries. His poems have been widely translated into many of the world's languages and transposed into various formats. Rumi has been described as the "most popular poet" and the "best selling poet" in the United States.
Muhammad Ahmad Muhammad Ahmad bin Abd Allah (Arabic: محمد أحمد ابن عبد الله; August 12, 1844 – June 22, 1885) was a religious leader of the Samaniyya order in Sudan who, on June 29, 1881, proclaimed himself the Mahdi, the messianic redeemer of the Islamic faith. His proclamation came during a period of widespread resentment among the Sudanese population towards the oppressive policies of the Turco-Egyptian rulers, and capitalized on the messianic beliefs popular among the various Sudanese religious sects of the time. More broadly, the Mahdiyya, as Muhammad Ahmad's movement was called, was influenced by earlier Mahdist movements in West Africa and other forms of Islamic revivalism that developed in reaction to the growing military and economic dominance of the European powers throughout the 19th century.
