The first professional training activity for future psychologists took place in Chile, in collaboration with a group of Mapuche schools and teachers from the IX Region, near the city of Temuco, in Chile. One of our volunteers, a student at the Autonomous University of Madrid, was arrested by the Chilean carabineros and accused of occupying land with one of the Mapuche teachers that they claimed as their own. That unfounded suspicion towards the activities of young Europeans in Mapuche land made us understand the added difficulties that this project would have and we began to organize it in the north of Peru, in Piura. Our first choice of collaboration with Mapuche communities had to move to Peruvian lands and today it is there where we carry out most of our training and intervention activities.
