In this chapter I summarize what has happened during the fifteen years of existence of an organized Psychology of Liberation (LP), and what has been produced as LP. I note the clear debts to the works of Freire, of Fals Borda, and Martín-Baró, and to the critical social psychology developed during the two last decades of the past century and with those coming in the beginning of the Millenium (such as Goldman, Foucault, Bruno Latour, Hacking, J.Ibañez, and T. Ibañez, among many others). I characterize LP as an ethical and political way to do psychology. I refer to several examples of LP in action, projects engaging with poor and marginalized communities to tackle injustice and improve quality of life, including aboriginal communities in Chile, Perú, Guatemala, and Mexico.
