From 1909, Adler's views on topics such as neurosis began to differ markedly from those held by Freud. As Adler's position appeared increasingly incompatible with Freudianism, a series of confrontations between their respective viewpoints took place at the meetings of the Viennese Psychoanalytic Society in January and February 1911. In February 1911, Adler, then the president of the society, resigned his position. At this time, Stekel also resigned his position as vice president of the society. Adler finally left the Freudian group altogether in June 1911 to found his own organization with nine other members who had also resigned from the group. This new formation was initially called "Society for Free Psychoanalysis" but it was soon renamed the "Society for Individual Psychology". In the period after World War I, Adler became increasingly associated with a psychological position he devised called individual psychology.
