Leon Trotsky's History of the Russian Revolution to Brest-Litovsk was written at the Brest-Litovsk peace conference a mere few months after the Bolsheviks had come to power. It gives an excellent introduction to the history of the Russian Revolution.

Written in the summer of 1917, in the heat of the Russian Revolution, Lenin’s State and Revolution is a key work of Marxism. Here, Lenin explains that, stripped of all non-essentials, the state is in the final analysis “groups of armed men”: the army and the police, in defence of the ruling class.

"Down with the counter-revolutionary bourgeoisie! Long live the free union of free peasants and workers of a free Ukraine with the workers and peasants of revolutionary Russia!"

Of the essays here presented for the reader’s attention, some are published for the first time, others appeared in various periodicals before the war. They deal with a question which now, naturally, arouses especial interest—the significance and role of national movements, the relationship between the national and the international. The biggest drawback, one most frequently encountered in all the arguments on this question, is lack of concreteness and historical perspective. It has become customary to smuggle in every manner of contraband under cover of general phrases. We believe, therefore, that a few statistics will prove anything but superfluous. A comparison with the lessons of the war of what we said before the war is not, in our view, unuseful. Unity of theory and perspective gives the essays continuity.
