what if Henri, Count of Chambord accepted the tricolour and became king of France? my personal opinions would be that France would help stabelise Spain and might even dissuade the Spanish-american war. Also with a bourbon on the throne tensions between Italy and France could increase. if ww1 happens Italy might back their ally Germany and invade France, hoping to regain Nice and get rid of bourbon restoration support. with italy on the german side the war would probably be over by 1915. i'm pretty sure France would just steam roll all the way to Tyrol, Germany and Austria would have to divert troops to help italy from the western and eastern front and it would be a easy victory for the entente. i know this last part is quite fanciful.
