A. J. Schem, The American Cyclopædia (1879)
“ Austria was excluded from Germany, and Hanover, Hesse-Cassel, Nassau, and Schleswig-Holstein, with Lauenburg and Frankfort, were annexed to Prussia; the states north of the Main were formed into the North German confederation under the headship of Prussia. The four South German states, Bavaria, Würtemberg, Baden, and Hesse-Darmstadt, were made independent states, but were closely united with the North German confederation by means of the Zollverein and defensive and offensive alliances. ”
