would come to a head during the following twenty years. External expectations of a unified Germany Other nationalists had high hopes for the German unification movement, and the frustration with lasting German unification after 1850 seemed to set the national movement back. Revolutionaries associated national unification with progress. As Giuseppe Garibaldi wrote to German revolutionary Karl Blind on 10 April 1865, "The progress of humanity seems to have come to a halt, and you with your superior intelligence will know why. The reason is that the world lacks a nation [that] possesses true leadership. Such leadership, of course, is required not to dominate other peoples but to lead them along the path of duty, to lead them toward the brotherhood of nations where all the barriers erected by egoism will be destroyed."

We need a nation courageous enough to give us a lead in this direction. It would rally to its cause all those who are suffering wrong or who aspire to a better life and all those who are now enduring foreign oppression." German unification had also been viewed as a prerequisite for the creation of a European federation, which Giuseppe Mazzini and other European patriots had been promoting for more than three decades: In the spring of 1834, while at Berne, Mazzini and a dozen refugees from Italy, Poland and Germany founded a new association with the grandiose name of Young Europe. Its basic, and equally grandiose idea, was that, as the French Revolution of 1789 had enlarged the concept of individual liberty, another revolution would now be needed for national liberty; and his vision went further because he hoped that in the no doubt distant future free nations might combine to form a loosely federal Europe with some kind of federal assembly to regulate their common interests. [...] His intention was nothing less than to overturn the European settlement agreed [to] in 1815 by the Congress of Vienna, which had reestablished an oppressive hegemony of a few great powers and blocked the emergence of smaller nations. [...] Mazzini hoped, but without much confidence, that his vision of a league
