You mean the dumb American definition of the word or actual fascism? I can't help you with the first but I don't think you can have the second without the Russian Revolution, it was the catalyst event that led to a dramatic polarization in the political discourse. Without the world War and the economic hardships of the next decades you won't see any fascist movement in any country. That said, the ideas are already there. Fabian socialism is pretty close to fascism, and you would still have a massive divide between a traditionalist authoritarian right and the socialist and anarchyst left in countries like Spain.
