Williams will speak about the character, origins and significance of the revolutionary upheavals of 1905. Called the “dress rehearsal” or “magnificent prelude” to 1917, the 1905 revolution in Russia contained all of the fundamental elements marking a new era in history—the epoch of proletarian revolution. The classes involved—the despotic aristocracy, the bourgeoisie, the peasantry and the working class—fought out the unresolved issues of 1905 12 years later, leading to the world’s first successful socialist revolution.

The tsarist autocracy was not overthrown in 1905, but its days were clearly numbered. The nascent capitalist class and its “liberal” allies proved incapable of overthrowing the tsar to clear the way for a parliamentary republic. When the working class began to advance its own demands, the liberal bourgeoisie showed that it feared the proletariat more than it resented the despotism of the tsar.

The revolutionary events of 1905 are dramatic: Bloody Sunday; spreading strikes in the industrial centers; a general strike in the fall; mutiny in the fleet; formation of the first Council of Workers’ Deputies in the capital; the tsar’s deceptive October manifesto, promising limited reform; armed uprising in Moscow and its bloody suppression; brutal revenge of the tsarist punitive expeditions, particularly against the workers.

All the political parties were tested in these events. Divisions between the two main wings of the Russian Social-Democratic Labor Party—the Bolsheviks and Mensheviks—began to emerge more clearly. Within the wide-ranging debates over all aspects of the revolution, a new voice was heard: the young Leon Trotsky, who briefly headed the Petersburg Soviet and then elaborated the Theory of Permanent Revolution as he drew the essential lessons of 1905.

Twelve years later, only the Bolshevik Party, led by Lenin and Trotsky, was able to re-arm itself and organize the broad masses of the working class for the seizure of power in October. The victory of 1917 would not have been assured without the immense revolutionary experiences of 1905.

Among the works translated by Williams are a series of essays by Trotsky from March 1917 currently being published on the WSWS, many appearing for the first time in English.
