Les Miserables, Volume V

The two most memorable barricades which the observer of social maladies
can name do not belong to the period in which the action of this work is
laid. These two barricades, both of them symbols, under two different
aspects, of a redoubtable situation, sprang from the earth at the time of
the fatal insurrection of June, 1848, the greatest war of the streets that
history has ever beheld.
