Mariano Delgado's book is dedicated to the 'Siglo de Oro', the golden age of Spain, providing a comprehensive overview of politics, economy, and religion. At the same time, it examines the cultural flourishing of the period with great names such as Velázquez, El Greco, Calderón, and Cervantes. But what characterizes this era? From around 1550 to 1680, the European hegemonic power Spain reaches the peak of its time as a colonial power. This phase is marked not only by an aggressive Catholic reactionary policy but also by the suppression of political freedoms. High-flying political ambitions are brutally enforced with the help of the Inquisition. Economically, the constant strain on resources – despite the rich gold revenues – threatens perpetual state bankruptcy. In addition to domestic political developments, the title also thoroughly examines the Spanish Empire.
