Both Brazil and Nigeria had their evolution in the same manner. The two countries were colonized by Western powers. They similarly had their experiences of policies of expropriation and exploitation of human and non-human resources. They were however subjected to various draconian and obnoxious policies and rules, featured by contradictions, inconsistencies with divide and rule tactics. The study finds out that apart from all these, there were violations of human rights inherent in the direction of slavery and slave trade to which the colonies were subjected. This work relies on the secondary sources of data collection in order to obtain reliable information about the activities of the colonial masters. Data were also sourced from the internet, governmental organizations and agencies concerned with the issue of colonialism. The study raises pertinent question about the desirability of the colonialism in the west; and how the colonies were brutally treated and governed via the use of indirect rule in politics as far as Africa political system was concerned. It noted that instead of being concerned with good governance, the colonial masters preoccupied themselves with primitive accumulation thereby using blacks against blacks to achieve their ulterior motives. The study therefore concludes that for the attainment of good governance and development in Africa, the idea of over dependence on West must be de-emphasized in order to pave way for violence free democracy. There should be concerted efforts on part of the African governments generally to educate the masses on evil effects of western colonial masters.
