Louis-Auguste Blanqui ranks among the most famous apostles of the nineteenth-century French Revolutionary tradition. His commitment to that cause was bound up with his longing to tap once more the energy that had inspired the popular uprisings of the French Revolution.

Here I examine the way four among them draw out varied and conflicting meanings from a life powerfully invested in a conception of the future deeply embedded in the past.
