Why did Usman dan Fodio lead a migration from Degel to Gudu in 1804?

Usman dan Fodio led a hijrah (migration) from Degel to Gudu in February 1804 primarily to ensure the safety of his community and to establish an independent Muslim state, free from the hostility of the Gobir ruling dynasty.1

During the 1790s, tensions escalated between Usman’s growing community and the rulers of Gobir. The sultan, Nafata, had previously issued restrictive proclamations against the Shaykh’s preaching and religious practices, fearing that the community was becoming a "state within the state". These tensions reached a breaking point under Sultan Yunfa, following a conflict where some of Usman’s supporters forcibly freed Muslim prisoners taken by a Gobir military expedition.1

Recognizing that Degel was no longer secure, Usman—drawing a parallel to the life of the Prophet Muhammad—undertook the migration to Gudu. This move marked the formal establishment of a new caliphate and the beginning of a jihad against the Gobir leadership, whom Usman deemed unbelievers for their attacks on the Muslim community.12
