The exercise of absolute power affects a country by limiting the rights of its citizens in favor of the rights and powers of the absolutist ruler, creating a tyrannical and dictatorial regime.
Explanation:
Absolutism is a type of political regime in which the holder of a power attached to his person, concentrates in his hands all the powers, and governs without any control. Absolutist rulers subject all aspects of life in the state to rigid control of the state administrative apparatus.
Absolutism in extreme cases turns to totalitarianism; which is possible when absolutist power leads the ruler to the possibility of controlling virtually all aspects of life in a society, from raising children in kindergartens, through employing staff in enterprises, to editing newspapers and directing artists.
Such as in the case of Tsarist Russia in the earliest 20th century, absolute power can lead to much cynicism towards the autocratic leader, in which he/she is seen as the centre of blame for all social, political, and economic circumstances. this can lead to uprisings, strikes and revolutions where the masses rise up against their sole leader
