This was posted on another political forum, as concerning the possibility that the US may experience a civil war--not so much like the American Civil War of the 1860s, as like the Spanish Civil War of the 1930s.
It is from The Silver Bear Cafe:
Much as the War Between the States began with the attack on Fort Sumter, so did the Spanish Civil War begin with the Coup d’Etat of July 1936. This was effectively an uprising by all forces of the Spanish right, which included two different factions of monarchists, nationalists, fascists (known in Spain as Falangists) and conservatives.
The igniting event was the election of 1936. This saw a very, very slim (less than 1 percent of the vote) victory of the Spanish left (socialists, Communists and anarchists) over the Spanish right. The right wing in Spain stopped planning to take over the Spanish Republic and instead decided that they were going to overthrow it.
The central republican government of Spain was very weak and had been making attempts to purge suspect right-wing generals from its ranks. To that end, General Francisco Franco, who ended up becoming dictator of Spain until 1976, was removed from his office as chief of staff and put out to pasture in the Canary Islands. When the uprising began, the nationalist rebels had the unanimous support of the Army of Africa, a 30,000-strong force that boasted some of the hardest core soldiers Spain had to offer. Many of these troops were Muslims from Morocco, who had been told that the republic planned to outlaw worship of Allah.
Indeed, Spanish Morocco was the base of operations for the rebels, with Generals Franco and Goded taking control of the Canary and the Balearic Islands, respectively. Any opposition in the Spanish colonial empire was quickly crushed with leading trade unionists and leftists simply executed by the rebel forces. The two trade union federations in Spain offered to help crush the uprising, but were told that there was nothing to worry about as the uprising was confined to Morocco and other overseas possessions.
The coup was less than a rousing success for the nationalist rebels, who invaded from their overseas bases. They failed to capture any major cities, which remained significant bases of support for the republican government. The republican government remained in possession of the lion’s share of Spanish territory. However, the republican government was at a disadvantage for two reasons: First, the nationalists had split the territory of peninsular Spain in half, dividing the country between republicans in the north and south while they controlled the middle.
Second, the republican government responded to the crisis by effectively mobilizing the far left in Spain as shock troops to terrorize the population into submission. Communists in particular were unleashed to execute and torture anyone even suspected of being a nationalist sympathizer. It didn’t help that the clergy bore the brunt of this, with nuns gang raped before being summarily executed. The republicans went so far as to exhume the bodies of dead religious figures and desecrate their corpses.
It is truly a nauseating thought...
