Note 42 — Chapter VI · THE CONVERSION OF THE SAXONS.
Reading edition
The Schleswig-Holstein question is proverbially complicated, being made so by the relations of the two provinces to each other, by the further relations of each separately and both combined to Denmark, and by the relations of all three to Austria, Prussia, etc. There was an almost ceaseless succession of wars over the question, or questions, from 1848 to 1866, when Schleswig-Holstein became a province of Prussia. For a full statement of the subject, see Bryce, Holy Roman Empire, note B.
