The father of modern political science is considered to be Niccolo Machiavelli
Explanation:
The Machiavellian term often refers to political deception, cunning and real politics. Although Machiavelli become best known for his work with principalities, scholars also note encouragement in other works of his political philosophy. During Italian Renaissance, Niccolo Machiavelli emphasised modern political science to directly observe political institutions and actors.
He presents a realistic view, arguing that even malicious measures should be taken into account if they help to secure and preserve the state of the ruler. Machiavelli opposes the idealistic model usage in politics and so described as "father of political model".
Machiavelli has a different tone in his less known work Livy Discourses. In this work, he explains the advantages of republicanism and what it means to be a good citizen.
