JAMB - History (2012 - No. 9)
Rabeh’s greatest challenge after conquering Borno was
normalizing relations with Sokoto Caliphate
rebuilding the armed forces
reviving the ailing economy
safeguarding the religion of Islam.
Explicación
Rabeh had an efficient army at that time and his immediate aim certainly did not include establishing any contact with the Sokoto caliphate as he saw himself as another Muslim reformer.
