Tidiani Tall (b. c.1840 died 1888) succeeded his uncle, El Hadj Umar Tall, as head of the Toucouleur Empire following Umar's 1864 death near Bandiagara. Tidiani was born the son of Alfa Amadou Tall, El Hadj Umar's elder brother. While a boy, his father went to Sokoto to visit his brother from his return to pilgrimage. During the twenty following years, he lived with his uncle and father in Timbo (Futa-Jalon), Jégunko(Futa-Jalon), Dinguiray Futa-Jalon and NioroKaarta before settling with his uncle in Hamdullahi Masina after the victory of the jihadists after the battle of Taayawal(1862). Tidiani and his cousin Muhammad Makki (c.1835- 1864)( Umar's second son) were de facto the heads ot the administrative branches of Hamdullahi. After the rebellion of the Fulas, led by the prince BaLobbo Bari allied with the al-Bekkay of Timbuktu assieged Hamdullahi from June 1863 to February 1864. In January 1864, Tijani was sent by his uncle to seek help from the Dogons of Bandiagara and to form a new army. The alliance led by Balobbo entered in the city at the start of February 1864 and Umar and his closest escaped in the 6 of that month. On February 11, Tidiani arrived to Déguembéré where his uncle just died with 15 others persons among others his sons, Muhammad Makki, Hadi and Muhammad Mahi.
Tijani succeeded in defeating the alliance in 1864. Tidiani was by now, more powerful than his cousin Amadou Madani ibn Umar, sultan of Segu.
