Ideological Foundations of British Non-Intervention in the Spanish Civil War: Foreign Office Perceptions of Political Polarisation in Spain, 1931-1936

In response to the outbreak of the Spanish Civil War in 1936, the British government adopted and maintained a policy of strict non-intervention throughout the conflict. Previous commentators, to varying degrees, have suggested this policy was largely a product of British hostility towards the Spanish Republic and designed to facilitate a victory for the military rebels who would subdue threats of a communist revolution. This analysis argues that historians have exaggerated British concerns about communism and that Britain saw the Republic as a viable political project that it wanted to succeed. Rather than focusing on British perceptions of only left-wing groups in Spain, this analysis also incorporates perceptions of the extreme right and fascist groups. British concerns about Spain's political polarisation laid the foundations of the policy of non-intervention, which sought to avert risks of the conflict escalating and solidifying the broader ideological polarisation occurring in Europe during the 1930s.
