This article is an answer to the growing interest arisen byAnalytic Psychology, a school of thought that compiles the work of the Swiss doctor Carl G. Jung (1875-1961). There exists a wide lack of information in our society on the contents of this school and thus this article seeks to offer wide review of its foundations. Given the fact that the aforementioned lack of knowledge is even greater in relation to its contributions to clinical work this paper presents the main contributions made by this approach to psychotherapy. Finally, a mention is made of the developments, revisions and postjunguian schools that have evolved from the original ideas of Jung to our days, as well as interesting encounter points with other psychoanalitical approaches.
