_The purpose_ of this study is the reflection on ways of philosophical legitimation for the "Self-made-man" idea in the worldview of the Renaissance and Reformation. _Theoretical basis._ Historical, comparative, and hermeneutic methods became the basis for this. The study is based on the works of Nicholas of Cusa, G. Pico della Mirandola, N. Machiavelli, M. Montaigne, E. Roterodamus, M. Luther, J. Calvin together with modern researchers of this period. _Originality._ The analysis allows us to come to the conclusion that casts (...) doubt on the still widespread belief according to which the emergence of the "Self-made-man" idea is localized by the process of forming the American cultural code and the ideological heritage of Benjamin Franklin. It is highlighted that the formation of this idea is the result of a long process that originated in the ancient world and gains a special impetus in the Renaissance and Reformation. Precisely in the cultural context of the latter, the ancient intention to recognize the individual’s right to self-determination and self-government, which in the depths of Christian theology acquires only a potentially universal character, becomes not only acceptable but also, in the context of Protestantism worldview, the only admissible, in fact, individual’s obligatory life guidelines. _Conclusions._ Humanistic and reformation thoughts quite naturally led to further ideological legitimation of the person’s idea of who is creating oneself. This legitimation was during the complex interaction of numerous factors of culture in the Late Middle Ages, as well as ideas and intentions inherited from Antiquity. Key among them was the gradual formation of a new social order, in essence, indifferent to paternalistic rudiments, together with the ethics of Protestantism corresponding to it. The latter does not only legalize but, de facto, sacralizes the individual’s reorientation from hopes for the synergy of God’s grace and own free will in personal salvation, toward the self-reliance and personal efforts, awareness of personal responsibility for the own fate as key principles of the "Self-made-man" concept.
