How did trade routes help spread news of the Sokoto jihad?

The spread of the Sokoto jihad was facilitated by a high degree of communication among the diverse peoples of the region. This connectivity was largely driven by the considerable interaction that occurred along established trade routes and rivers.12

These networks, which drained the northern plains toward the Niger-Benue valley and extended through the delta and across coastal lagoons, acted as conduits for information. As a result of this movement, the call to jihad issued by Usman dan Fodio in Gudu reached far beyond its point of origin. The message resonated throughout the Hausa states—including Kano, Katsina, and Zaria—as well as in Borno, Bauchi, Gombe, and Adamawa. Eventually, the movement’s influence spread to areas with pockets of Fulani scholars, such as Nupe and Ilorin, effectively drawing these territories into a single politico-religious system centered at Sokoto.12
