This paper aims to present a historical discussion about the emergence of the concept of adolescence, the consequences and ramifications that such a perspective effects in creating a culture of rights. Born in the ideals of modernity, adolescence brings with it a certain conception of temporality related to the rise of individualism and the enhancement of human development as a career. It is only from a design trajectory needed to build the free and autonomous individual symbolized by the adult that becomes possible to reflect on the teenager as a subject of rights. Therefore, the emergence of adolescence as a category object of study and care also entails an entire comprehensive discussion of rights and duties culminating with the idea of being a teenager as a right.
