The article outlines the studies conducted in Italy on the history of psychology since the 1970s, with particular attention to those elaborated in the 1990s. Reference is made to the institutions, authors, congresses, and other initiatives that in the course of 3 decades have promoted the growth of the history of psychology, and a review is presented of the principal research themes undertaken by scholars. An attempt has been made to identify the principal historiographic tendencies and to illustrate the passage from a sort of "positivistic" historiography to an orientation that could be considered multifactorial or one of complexity, attentive to both the internal and the external components of the scientific enterprise, although with a propensity for the history of ideas.
