What led to the breakdown of MacPherson constitution?

The breakdown of the MacPherson Constitution in Nigeria was primarily due to increasing ethnic tensions and political rivalries among the regions. The constitution, which aimed to provide greater regional autonomy, inadvertently intensified regional competition for power and resources. Additionally, the lack of adequate representation for minority groups and the failure to address socio-economic disparities contributed to widespread discontent. This culminated in political instability, leading to the eventual military coup in 1966.
