Carlistreich

Point of Divergence
In 1872 the Carlists rise again, pretty typical, huh? But this time Austria supports them with soldiers while the newly formed German Empire, just to annoy them, supports the Liberals of King Amadeo I of Savoy. This continues as the other ones until in 1874, when Prussian expeditionary troops attack Austrian expeditionary troops. This causes manifestations against Prussia in the entirety of Austria and Hungary, which finally declares war. The French Republic, which has been observing and secretly supporting the Carlists (although they are supposed to be a democracy) decide to stay out of it but when the auto denominated Charles VI of Spain agrees to moderate his traditionalism and liberalize a little the government the support openly explodes in France, which would finally join the war in late 1875.The Germans managed to hold the Austrians and the French for two years, and, animated about this and wanting to help their German friends, Italy enters the war. Finally, after many battles and deaths the war would end in 1885, leaving the Carlist claimant as the king in Spain and having Germany and Italy shut down by the French and Austrians.
