    Spanish Nationalist fighters, 30 Dec 36

    When an initial military coup failed to win control of the entire country, a bloody civil war ensued, fought with great ferocity on both sides. The Nationalists, as the rebels were called, received aid from Fascist Italy and Nazi Germany. The Republicans received aid from the Soviet Union, as well as from International Brigades, composed of volunteers from Europe and even the United States.

    The war was an outcome of a polarization of Spanish life and politics that had developed over previous decades. On one side, the Nationalists were for the most part important military men, most of the landowners and many businessmen. They were a Falangist group led by General Francisco Franco. On the other side, the Republicans were primarily the urban workers, agricultural laborers and many of the educated middle class. They were loyal to the current Second Spanish Republic (he short-lived First Spanish Republic emerged in 1868 after the overthrow of Queen Isabella II).

    For both Adolf Hitler and Benito Mussolini, the Spanish Civil War would be an ideal testing ground for their ground and air weaponry and a chance to flex their ideological muscle on a world stage.

    The Spanish Civil War will finally come to an end on 28 Mar 39 with Franco on top. Franco will then brutally rule Spain for the next 36 years, until his death in 1975.

    Partial view of the destruction of the
    Port Chicago disaster, 17 Jul 44

    On 08 Aug 44, continuing unsafe conditions will inspire hundreds of naval servicemen to refuse to load munitions, an act known as the Port Chicago Mutiny. Fifty men - called the "Port Chicago 50" - will be court-martialled, convicted of mutiny and sentenced to long prison terms. 47 of the 50 will be released in January 1946; the remaining three will serve additional months in prison.

    Widespread publicity surrounding the case turned it into a cause celebre among African-Americans and white Americans; it and other race-related Navy protests of 1944-1945 led the Navy to change its practices and initiate the desegregation of its forces beginning in February 1946.
