During the next twenty years he lived with his uncle and father in Timbo, Jégunko, and Dinguiraye, all in the Futa Jallon, as well as in Nioro du Sahel in Kaarta.
The native Fula people, led by the prince Ba Lobbo Bari and the al-Bekkay of Timbuktu, revolted and besieged Hamdullahi from June 1863 to February 1864.
The alliance led by Balobbo entered Hamdullahi at the beginning of February 1864, and Umar and his companions escaped on the 6th of that month.
Ahmadu Tall, Umar's eldest son and Faama of Segou, was not able to re-establish control over Tijani's portion of the empire.
[1] Tijani died in 1887 and was succeeded by Muniru, who was eventually superseded by Ahmadu Tall[clarification needed] after the fall of Segou to the French in 1890.
