Ali Jedo was among the first to participate in the jihad in Sokoto during the 19th century. He already commanded an army with its base in Iname in Konni. He was appointed commander of the army by Uthman dan Fodio becoming the Sokoto Caliphate's first commander. Jedo's descendants continued to hold that position till the end of the caliphate in 1903.
Ali Jedo was described as "a fiery warrior with a reputation for hot-headedness".[3] An example of his hot-headedness can be attributed to an oral tradition of when he killed a man from Kebbi who dared enter his home and demanded the return of a borrowed horse. Because of this incident, Shaikh Uthman is said to have refused to see him again. The subsequent Sultans also had trouble in disciplining Ali Jedo.[4][5]
Abdullahi dan Fodio and Ali Jedo both led Sokoto's expedition into Kebbi in 1805. The capital, Birnin Kebbi, was successfully captured on 13 April of the same year. This success allowed some of the Muslims of Sokoto to move to Gwandu establishing the Gwandu emirate led by Abdullahi. Not long after the establishment of Gwandu, Shaikh Uthman divided the responsibilities of the Caliphate. He gave the west to Abdullahi, the east to his son Muhammad Bello and the north to Ali Jedo. The northern part of the caliphate reached as far as Filingue and Adar. Konni remained under Ali's sphere of influence as he was still recognised as the leader of the Konni Fulbe. Binji was established by the sons of Ali but he remained in Iname, his old base to the east of Binji.[6] King Yunfa's sword was given to Ali and his descendants at Binji hold in custody as the symbol of the Amir al-jaish al-Islam and District Headship of Binji to this day.[7]
Towards the end of his life, as he grew older, Ali used his sons as his deputies and left them in charge of the army. His most senior son Abu Bakr, acting as commander of the army, was killed in a Battle led by Sultan Abu Bakr Atiku. Abu Hasan bin Ali Jedo, another son of his, took over this position as acting Amir al-jaish. Shortly after the fourth Sultan of Sokoto, Ali bin Bello, was appointed in 1842, Ali Jedo retired from his position as supreme commander of the army, leaving its management to his sons.[8] Ali Jedo died thirty years after Uthman dan Fodio in 1846 or seven years after Ali bin Bello's ascension in 1849.[9]
