The Spanish Revolution, 1931–1939 (Trotsky book)

The Spanish Revolution, 1931–1939 is a collection of Leon Trotsky's writings about the Spanish Civil War.

Throughout this period, Trotsky asserted there was an urgent need for a mass revolutionary party, sharply criticised the conciliatory actions of the POUM faction such as abandoning the Left Opposition program, the intrigues of the Stalinist Comintern in suppressing the left-wing forces and facilitating the ascent of fascist Spain.

In his observations and analysis, Trotsky proposed a number of actions including the temporary entry of sections of the International Left Opposition into the Socialist parties, united front with left-wing parties including the CNT and anarchist groups along with the formation of workers councils.
