ROBERTS, Michael. The Early Vasas. A History of Sweden 1523-1611
[From the cover] "While offering a full account of [Gustav Vasa's] achievements, this book gives equal attention to the crucial half-century which followed Gustav Vasa's death - a half century which prepared the way for Sweden's emergence as a great power. Professor Roberts provides an account of the course of the Swedish Reformation; he analyses those trans-Baltic entanglements which were to assume such importance, both for Sweden and for Europe, in the next century; and he pays particular attention to the constitutional controversies which reached their climax, though not their end, with the deposition of King Sigismund and the Bloodbath of Linkoping"
