The Spanish State (Estado Español) was the formal name of Spain from 1936 to 1978, under the régime of GeneralísimoFrancisco Franco (d. 1975), "by the grace of God, Caudillo of Spain and of the Crusade".
When the Spanish Civil War broke out in 1936, the Nationalist forces immediately began using the form the Spanish State rather than the Spanish Republic or the Spanish Monarchy, out of deference to the differing political sensibilities of the members of the Nationalist coalition, which included the fascistic Falangists and the rival monarchist parties the Carlist and the Legitimists.
The Spanish State was declared a monarchy in 1947, but no king was designated; the Chief of State, Franco, reserved for himself the right to name the person to be king, and deliberately delayed the selection due to political considerations. The selection finally came in 1969, with the designation of Juan Carlos de Borbón as Franco's official successor (this selection was an unpleasant surprise for many interested parties, as Juan Carlos was the rightful heir for neither the Carlists nor the Legitimists).
With the death of Franco and the dismantling of the Franquist régime, the Spanish State ceased to exist, being thoroughly reconstituted as the Kingdom of Spain, a constitutional monarchy, where the head of state reigns, but does not rule.
"Estado Español" and its translations is still used by nationalists who don't acknowledge Spain as a real nation, but as a state currently holding several nations.
One of the Nationalists' principal motives, claimed at the time of their initial uprising, was to confront the anticlericalism of the Republican regime and to defend the Roman Catholic Church, which was censured for its support for the monarchy and which many on the Republican side blamed for the ills of the country.
The Spanish Civil War was also an example of total war, where the bombing of the Basque town of Guernica by the Legión Cóndor, as depicted by Pablo Picasso in Guernica, foreshadowed episodes of World War II such as the bombing campaign on Britain by the Nazis and the bombing of Dresden by the Allies.
In October, the Nationalists launched a major offensive toward Madrid, but increasing resistance by the government and the arrival of "volunteers" from the Soviet Union halted the advance by November 8.
