The previous ruler, Frederick William IV., was a gifted and learned man, but he lacked soundness of judgment and strength of will--qualities which are of more worth in governing than graces of the intellect. At the time of the revolutionary outbreaks of 1848 he capitulated to the Berlin mob and declared for a constitutional régime in which Prussia should merge herself in Germany; but when the excesses of the democrats had weakened their authority, he put them down by military force, refused the German Crown offered him by the popularly elected German Parliament assembled at Frankfurt-on-Main (April 1849); and thereupon attempted to form a smaller union of States, namely, Prussia, Saxony, and Hanover. This Three Kings' League, as it was called, soon came to an end; for it did not satisfy the nationalists who wished to see Germany united, the constitutionalists who aimed at the supremacy of Parliament, or the friends of the old order of things. The vacillations of Frederick William and the unpractical theorisings of the German Parliament at Frankfurt having aroused general disgust, Austria found little difficulty in restoring the power of the old Germanic Confederation in September, 1850. Strong in her alliance with Russia, she next compelled Frederick William to sign the Convention of Olmütz (Nov. 1850). By this humiliating compact he agreed to forbear helping the German nationalists in Schleswig-Holstein to shake off the oppressive rule of the Danes; to withdraw Prussian troops from Hesse-Cassel and Baden, where strifes had broken out; and to acknowledge the supremacy of the old Federal Diet under the headship of Austria. Thus, it seemed that the Prussian monarchy was a source of weakness and disunion for North Germany, and that Austria, backed up by the might of Russia, must long continue to lord it over the cumbrous Germanic Confederation.
