For a hundred years, Sweden was the international military power of Northern Europe, in control of the entire Baltic region and among the first to colonize in Africa and America. But the history of Sweden, Finland, the Baltic States, Poland, and Prussia is largely neglected in American classrooms and scholarship. This book fills a large void in European history as it is generally presented to the American student and reader. This narrative covers Sweden’s Age of Greatness (1632-1718) and the warrior-kings who governed that age. It chronologically describes the political and religious events of the sixteenth and seventeenth centuries and reveals how these events produced the climate for European global expansion, including the exploration and colonization of the New World. The story traces history through the reigns of Sweden’s ambitious rulers, beginning with the presumably Swedish Goths who ravaged the Roman Empire in the 2nd century CE and continuing through the end of the empire in the early eighteenth century. A thorough epilogue documents the cultural flowering in the arts and sciences that commenced in the Age of Greatness and continued to blossom in the centuries that followed. This final section of the book pays special attention to the personalities that drove Sweden’s far-reaching cultural progress.
