Which leader, influenced by the Sokoto Caliphate, established a theocratic state in Masina in the early 19th century?

The leader who established a theocratic state in Masina in the early 19th century, influenced by the Sokoto Caliphate, was Seku Amadu.

Seku Amadu, also known as Amadu Hammadi Bubu, was a Fulani Islamic leader and reformer. Under the inspiration of the reformist ideology of the Sokoto Caliphate, founded by Usman dan Fodio, Seku Amadu sought to establish a similar religious and political structure in what is now modern-day Mali. The Sokoto Caliphate, established in present-day Nigeria, was known for its promotion of Islamic governance based on Sharia law.

In the early 19th century, Seku Amadu led a jihad to overthrow the existing local traditional rulers in the region of Masina. This resulted in the creation of the Massina Empire, also referred to as the Massina Theocratic State, where Islamic laws and educational systems were strictly enforced. The legacy of Seku Amadu's rule highlights the spread and influence of Islamic governance in West Africa during this period, modeled after other successful theocratic states like the Sokoto Caliphate.
