An unanswered question on the making of Pedagogy of the Oppressed is when, where and how this book was written, edited, and published. The Preface of the original Portuguese handwritten manuscript is dated in Chile by 1967. Some scholars imply that the manuscript was finished sometime in April 1969. By then, Freire had left Chile and three of his books had been published by UNESCO's Institute of Research and Training in Agrarian Reform, ICIRA. Freire himself had already committed the English translation of Pedagogy of the Oppressed together with the Spanish translation published by Tierra Nueva in Uruguay.
