The title of this book attempts at exposing a scenario: the one glances between societies and citizens that inhabit both sides of the Atlantic. Throughout its recent history, Spanish and Americans have shared experiences, welcomed and viewed each other with suspicion. For this reason, the relationship between both citizenships is also the account of their (dis)encounters. Throughout the 20th century, citizens of both countries have built, apart from official status, relationships whose results are worth to be looked at. This book collects some of those experiences: Stories about human groups and people whose life experience developed in both continents, despite the sociopolitical circumstances of each moment or precisely on the subject of them. The modernizing process, the role of women in education, the journeys, and learning of the Spanish in exile, the topics, prejudices, and legends that have circulated for decades back and forth, the academic and scientific exchanges, the student activism of the sixties or anti-Americanism from which Spain has never been immune, are some of the topics covered in this volume. Suspicion happens and will continue to happen, and it is to be hoped that mutual empathy will continue to experience the ups and downs of the events. However, the Hispanic-American ties can only go further, so it is convenient to dissect them in their history to understand them in a continuous exercise of curiosity and dialogue.
