Originally published in 1937 during the Spanish Civil War, the country was split into pro-fascists and pro-communists, the author felt that the conflict in Spain threatened to develop into an international war. He looks back to wars of the sixteenth century to find a precedent for this dramatic duel between two political conceptions.
