Those Magical 20s-1
The world where Alberto comes from is very similar to a standard Earth world, with the divergence located somewhere in ancient history, where people discovered the existence of magic and how to harness it. Of course, people being people, no major development was made through the ages, either by political strike, religious idiocy, or plain bad luck.
That being said, the use of magic never really died, even if it had to go 'underground' for centuries, as open usage of magic was a quick way to end up dead, despite the uncountable times where people just figuratively turned their face away at displays of magic to heal wounds or treat the sick.
This changed during the Enlightenment, where magic was gradually brought out to the open as part of Nature itself and studied as a science. As the 19th Century came, along with the Napoleonic Wars, the effort of mages, both as combatants and medics, finally granted them a position of respect within the societies of the world.
Around the middle of the century, the first organized, State-sponsored Magical organizations showed up, and the world met a booming development as the skills that were previously transmitted orally were finally compiled and spread out in an effort to educate the masses, and a technological boom marked the entrance into the 20th Century.
However, the tensions between the European countries were still there, disguised in a technological race, and the Sarajevo assassination were the spark to the 1914 hostilities, with the difference that in this world, it was pretty much limited to the European countries and their colonies. Still, the nature of the engagements and the destructiveness of massed magical attacks earned it the dubious fame of being called a Great War.
Eventually, the war ended in 1918, but unlike what happened in our own world, Versailles was never signed, for the simple reason that a dog ate the paperwork (multiple people would swear the dog was a magical sentient who decided to act for the good of all. A medal is waiting for him in case his identity is ever found out). Forced into yet another round of negotiations, a more stable peace accord was signed, where Imperial Germany was allowed to walk out with their heads raised high, despite their defeat (and French hardliner whining).
All in all, it was a more stable and prosperous Europe that would live through the decade of the 1920s, where people were able to swallow their pride and work with their former enemies to fix the scars of war that torn Europe apart, a decade of reason after four years of madness and ruin. This decade of reason also saw the birth of the European Union: shocked by the fruits of rampant nationalism, the seed of the second round of Versailles quickly blossomed on a tree that is showing great promise for the future of Europe.
