This study tries to examine Hannah Arendt on power and its implications for Nigeria. The study adopted expository and analytical method. The findings of the study revealed that Hannah Arendt's concept of power is more or less an authority that depends on communicability and not coercion, force or violence but rather by persuasion in the art of governance. Power resides with the people in plurality. Hannah Arendt used power to recommend democracy as the best form of government where power resides with the people. Therefore, it concluded that political power in Nigeria belongs to the people and remains with the people except it is given out as a mandate retrievable in a proper democracy. Political power emerges where people come together and act in concert but it derives its legitimacy from the initial meeting rather than from any action that can follow it.
