Bello, Emir Abdullahi dan Fodio, Sultan Abu Bakr Atiku, and Nana Asma'u devoted significant time to chronicling histories, writing poetry, and Islamic studies. A number of manuscripts are available and they provide crucial historical information and important spiritual texts. This role did diminish after the reign of Bello and Atiku. Legacy Although it has lost its former political power, the Sokoto Sultanate Council continues to exist, and the Sokoto Sultans are still "leading figures in Nigerian society". Even the Presidents of Nigeria have sought their support. Due to its impact, the Sokoto Caliphate is also revered by Islamists in modern Nigeria. For example, the Jihadist militant group Ansaru has vowed to revive the Sokoto Caliphate in order to restore the "lost dignity of Muslims in black Africa". Culture The Fulani ruling class engaged in marriage alliances with Hausa families. The Hausa language became the language of administration and main medium of poetry in the caliphate.
