The Ogiso dynasty in Benin failed due to a combination of factors, including economic disorder, weakness and dependence on rulers, and resentment against the system.
During the Ogiso dynasty, which lasted from approximately 900 BC to 1170 AD, the rulers of Benin were regarded as divine and enjoyed significant power and wealth. However, over time, the economic system became increasingly disordered, and there were growing tensions between the rulers and the people.
In addition, the rulers became increasingly weak and dependent on their subordinates, who often acted as de facto rulers. This weakened the overall authority of the Ogiso dynasty and made it more vulnerable to internal and external threats.
Finally, there was growing resentment against the system, as many people felt that the rulers were abusing their power and failing to provide adequate protection and support for the people. This led to growing unrest and eventually contributed to the collapse of the Ogiso dynasty.
Therefore, it was not just one factor but a combination of economic, political, and social factors that contributed to the failure of the Ogiso dynasty in Benin.
