Neopatrimonialism is a system of social hierarchy where patrons use state resources in order to secure the loyalty of clients in the general population. It is an informal patron–client relationship that can reach from very high up in state structures down to individuals in small villages.
Neopatrimonialism may underlie or supplant the bureaucratic structure of the state in that only those with connections have the real power, not those who hold higher positions. Further criticisms include that it undermines political institutions and the rule of law, and is a corrupt (but not always illegal) practice. Neopatrimonialism also has its benefits, however. Neopatrimonalism can extend the reach of the state into the geographical and social peripheries of the country, provide short term stability, and facilitate communal integration.
Neo-patrimonialism, as defined by author Christopher Clapham of The Nature of the Third World State, is a "form of organisation in which relationships of a broadly patrimonial type pervade a political and administrative system which is formally constructed on rational-legal lines." It is a system in which an office of power is used for personal uses and gains, as opposed to a strict division of the private and public spheres.
