'The end of the local world' (1914-1949) is a chain of events that begins with a fuse: in 1870 London takes note of the birth of a new power: Germany.

Why Spain's absurd war in Morocco
The answer lies in the French archives that we now understand well within this framework
London negotiates with Paris and at the end of the talks a loose end remains: London does not want to lose its control of the Strait of Gibraltar and so London and Paris come to an agreement: we entrust northern Morocco (the "Rif") to Spain on condition that it does not install gun batteries on the coast. Said and done.
And this absurd and damned war in Morocco will be one of the roots of an even greater tragedy: the Spanish Civil War. Conservative voices of the time shouted: "What the hell are we going to Morocco for?" And also socialist voices. Nothing. The Spaniards were good Ukrainians ready to die on the altar of the Anglo-empire.
