Hadji Oumarûl Foutiyou Tall (ʿUmar ibn Saʿīd al-Fūtī Ṭaʿl, Arabic: حاج عمر بن سعيد الفوتي طعل, c. 1794 – 1864 CE), born in Futa Tooro, present-day Senegal, was a Senegalese Tijani sufi Toucouleur Islamic scholar and military commander who founded the short-lived Toucouleur Empire, which encompassed much of what is now Senegal, Mauritania, Guinea and Mali.The honorific El Hadj (also al-Hajj or el-Hadj), reserved for a Muslim who has successfully made the Hajj to Mecca,[2] precedes Omar Tall's name in many texts, especially those in Arabic.Later he also took on the honorifics Amir al-Mu'minin, Khalifa, Qutb (pole of the universe), vizier of the Mahdi, Khalifat Khatim al-Awliya (successor of the seal of saints), and Almami (Imam).[1] Omar Tall was born about 1794 in Halwar in the Imamate of Futa Toro (present-day Senegal), the tenth of twelve children.[1] Omar Tall's message appealed to a large cross-section of the Sahelian population in the mid-19th century, including Fula, Soninke, Moors, and others.After a series of emissaries to Tall were rebuffed, and one prominent griot even converted to Islam, Yambi pre-emptively attacked the community but was defeated in September 1852.In 1860 Omar Tall made a treaty with the French that recognized his, and his followers', sphere of influence in Futa Toro and assigned them the Bambara states of Kaarta and Segu.[11] While Omar Tall's wars thus far had been against the animist Bambara or the Christian French, he now turned his attention to the smaller Islamic states of the region.[10][12][13] Now controlling the entire Middle Niger, Omar Tall moved against Timbuktu, only to be repulsed in 1863 by a combined force of Tuaregs, Moors, and Fulas.Omar Tall's state forbade dancing, the use of tobacco, alcohol, charms, pagan ceremonies, and the worship of idols.The primary function of Omar Tall's state was predatory warfare, slaving, the accumulation of booty, and the reform of morals.
