It is a pleasure for us to write the prologue of this book, which is the result of collaboration between the Law School of the University of Deusto (Bilbao, Basque Country, Spain) and the Law School of the Unichristus University in Fortaleza (Brazil). The collaboration came about in the middle of the Covid-19 pandemic, and we were able to lay the foundations for a joint effort whose first result is the book you hold in your hands. The contributions included in this volume were presented at the I Congress of the Students of the Master’s Degree (LLM) in International Legal Studies of the Law School of the University of Deusto and the Students of the Master’s Degree in Law of the Law School of the Unichristus University, which was held on May 12 and 13, 2021 in the online format. Those who were fortunate enough to attend this event could attest to the quality of the research and the relevance of the topics addressed. Following the central themes that are addressed in our respective Master’s programs, there were three thematic axes of the Congress: the impact of new technologies on human rights, the situation of prisons from the perspective of human rights, and the advances that are being produced in the sphere of indigenous peoples’ rights both in Brazil and abroad. Of all the papers presented, we carried a selection taking into consideration both the quality of the work presented and the relevance of the chosen theme. We are happy to present this work to you, the first stone of a collaboration between our universities that we hope will produce many more fruits like this one. Another example of our willingness to cooperate is that a Unichristus student has just started her Master’s degree in International Legal Studies at the University of Deusto. We hope to continue taking steps to make university higher education an instrument of social transformation to create a juster, more humane, and more sustainable world.
