Book by Associate Professor of the National Research University "Higher School of Economics" R.Yu. Belkovich represents the first attempt at a conceptual generalization of the history of radical socio-political thought born on the territory of the modern United States of America. The book examines the ideological prerequisites for the emergence of American radicalism, brought from Europe (republicanism, Protestantism, common law traditions, etc.), as well as the original forms that they acquired on new soil. The author interprets the history of the development of political and legal thought in the New World as a reflection of the continuous struggle of the population against the centralization of power and the reproduction of European authoritarian practices in the American context. Analysis of figures and movements that are significant for the American intellectual landscape makes it possible to identify the tradition of resistance to tyranny going through centuries, uniting religious radicals of the 17th century V. and modern day gun rights advocates. Property against capitalism, jurisprudence against laws, conservatives against the state - this paradoxical, at first glance, set of ideological conflicts characteristic of the political culture of the United States indicates the need to understand American radicalism as an independent phenomenon of intellectual history, an integral product of an autonomous cultural ecumene.
