The empire was divided into provinces, each of which was governed by a provincial governor appointed by the ghana. The provincial governors were responsible for maintaining law and order, collecting taxes, and administering justice. The ghana also had a personal bodyguard, which was used to protect him and enforce his decrees.
The Ghana Empire was a well-organized and efficient state, and its centralized government was largely responsible for its success. The ghana's power was bolstered by the empire's control over the gold trade, which gave him access to immense wealth and resources. As a result, Ghana was able to maintain a large and powerful army, which further strengthened its security.
The centralized government of the Ghana Empire enabled it to survive for several centuries despite the challenges it faced from external threats such as attacks from rival kingdoms and internal instability such as revolts by provincial governors. However, the empire eventually declined and collapsed in the 13th century due to a combination of factors, including external invasions, internal conflicts, and a decline in gold production.
