Immediately after the former European colonies in Africa game Independence what model of government did they usually adopt

After gaining independence, many former European colonies in Africa adopted a model of government based on the Western democratic system. This typically involved establishing a republican form of government with a constitution, a separation of powers among the executive, legislative, and judicial branches, and periodic elections to choose their leaders. However, in practice, some African countries faced challenges in fully implementing these democratic principles and often experienced periods of authoritarian rule, military coups, or one-party states.
