Many young men from the United States and other countries joined the Spanish Loyalist forces in defense of democratic ideals in a war that was won by the dictator, Francisco Franco. In reality, the Spanish Civil War was the first battleground for World War II, testing the forces of Nazism, Communism, and Fascism against either the republican or royal form of government. Later, in 1937, he went to Spain to cover the war for the North American Newspaper Alliance. He predicted the civil war would begin in 1935, and when it erupted in 1936, Hemingway began writing and making speeches to raise funds for the Loyalist cause. He had visited Spain again during the summer of 1931 after the overthrow of the monarchy.

While still a foreign correspondent in Paris, Hemingway had watched the Spanish political situation developing under the reign of Alfonso XIII. For Whom the Bell Tolls, published in 1940, grew out of Hemingway's personal interest in the Spanish Civil War of the thirties.
