After the defeat of the revolution in the year 1849, Marx and Engels did not share the illusions of the vulgar democracy that grouped itself around the upstart provisional governments in partibus, [i.e. the post-revolutionary governments then emerging throughout Europe during the immediate reaction].
This vulgar democracy deluded itself on an imminent decisive victory of the “people” over the reactionary “usurpers” of the revolution.
We, however, foresaw a long struggle, after the removal of these reactionary “usurpers” of the revolution, between the antagonistic groups now concealed within this supposedly united “people” itself.
The vulgar democracy confidently expected renewed outbreaks of the revolution every day.
We declared as early as the autumn of 1850 that the first chapter of the revolutionary period was now closed, and that nothing further was to be expected until the outbreak of a new world crisis.
For this reason we were excommunicated—as traitors to the revolution—by the very people who later, almost without exception, rushed to make their peace with Bismarck—so far, of course, as Bismarck found them worth his trouble.
