The early 17th century was a time of great literature the era of Cervantes and Shakespeare but also of international tension and heightened diplomacy. This book looks at the relations between Spain under Philip III and Philip IV and England under James I in the period 1603-1625. It examines the essential issues that established the framework for diplomatic relations between the two states, looking not only at questions of war and peace, but also of trade and piracy. Óscar Alfredo Ruiz Fernández expertly argues that the diplomatic relationship was vital to the strategic interests of both powers and also played a highly significant role in the domestic agendas of each country. Based on Spanish and English archival sources, England and Spain in the Early Modern Era provides, for the first time, a clear picture of diplomacy between England and Spain in the early modern era.
