This talk will explore the Spanish Revolution of the 1930's, one of the most dramatic revolutions of the 20th century. The main events discussed will include: the election of Second Spanish Republic, the Asturian insurrection, the election of the Popular Front government in 1936, the fascist uprising and the revolutionary response to it, and the civil war that lasted until the defeat of the Popular Front in 1939. The talk will pay particular attention to the political parties and organizations on the left and their political limitations in leading the revolution forward. In addition, it will argue that what the Spanish revolution needed to be successful was a revolutionary party of working class to lead the movement to take political power, a crucial step in the battle to liberate the European continent from fascism and world war.
