Let's say Napoleon III is less religiously Imperial and doesn't intervene in the Crimean War and the Protection of the Papacy. So Sardinia does not join. And the Russian ally, Austria who Russia supported less than a decade back in the Hungarian Revolution of 1848 possibly joins or stays neutral. Also using Austria's relationship with the Turks to push the Austrians against the Turks would be smart, Britain decides to still help the Ottomans as they did in the Second Ottoman-Egyptian War. Also Russian generals are smarter and more sober. The Austrian-Russian forces supported by the local civilians push through the Balkans and Eastern Anatolia, Britain does not attempt Crimea and their army is not enough to stop the Russians, Greece might convince Britain to pull out and Greece could convince Russia and Austria to not be so harsh against the Ottomans, the Russian-Austrian fleets are defeated anyways. Austria annexes Bosnia, some of Serbia, Serbia gains more autonomy and so does Bulgaria and the Armenians, Greece gains a little territory in the Empire. Russia might expand in Eastern Anatolia and a little bit in the Balkans. Bulgaria is smaller Pre-Turkish War. Orthodox Christians gain rights in the Holy Land. Russia and Austria could continue to bully The Turks, the Great Eastern Crisis could happen earlier with a Weaker Ottoman Empire. Russia could take advantage of it and Start another Russo-Turkish War. The sides would be pretty much the same, Britain gains Cyprus, Greece, Russia and the Austrians expand into the falling Empire. Serbia, Bulgaria, and Armenia gain independence. The Balkans except Montenegro and Greece are pretty much Russian puppets. A faction might form between Russia, Austria-Hungary and Germany. The Holy Alliance might adapt more to the new age. The Balkan Wars would mean the end of Ottoman Power in Europe, Constantinople coming under Russian power and the Western Coast of Anatolia coming under Greece. Bulgaria gains most of Thrace, Serbia and Montenegro unite, Bulgaria gains most of Macedonia, while the rest is split between Greece and Serbia, Albania is split. Greece might join the Holy Alliance due to a good relationship with the Russians and Britiain and Greece being at ends since the Crimean Wars. The Great War might erupt late, also Russian strength might have had Russia complete the Trans-Siberian Railway. The Great War could start between Italy and Austria over Venice since the Italians were never able to take it with Russian backing of Austria, meaning Italy's campaign in Venice was a complete failure and since Prussia didn't want a bad relationship with Austria, left it as that. The Quadruple Entente with France, Italy, Turkey and Britain maybe Japan too, verse Germany, Russia, Austria-Hungary and all the Balkans. The Entente could not hold against the Superior German army, the Russian numbers, Balkan-Austria-Hungarian support. Japan would be pretty much the only power who could attack Russia's mainland, the allies would be completely outnumbered. A United German Navy and a Stronger Russian navy could maybe overcome the British blockade, also Russia would be in charge of most of the supplies, its industrial manpower would mean the Germans wouldn't run out of supplies until at least over 6 years into it. Germany already winning in Europe wouldn't be so scared about the US, the Lusitania might get destroyed but Russia might scare the US enough where they won't get intervened by means of military. Austria-Hungary, and Germany would be focusing its entire army and military from the start on the Western front which is including the Italians. Also the Schlieffen plan would be successful maybe with Russian support. The Holy Alliance would most likely win, Britain would not lose land except Cyprus which is to Greece. Japan might give up at least Northern Korea. The Ottomans would give Hejaz and Palestine independence, Britain would make sure the Ottomans don't collapse and maybe bring Palestine under Britain. The Ottomans would reform the Empire, more nationalistic, militalristic and stable. Fascism would form in Italy, Austria gaining Lombardy. Luxembourg and parts of Eastern Belgium and parts of Lorraine to Germany. Russia would expand in Anatolia. Communism would take France, maybe Algeria and Tunisia with it, communism might also take Italy depending on things. The Ottomans would become nationalistic, Russia would adapt and become more liberal, maybe decentralize a little bit, same with Austria. Russia would expand its influence in Iran and China. Kuril Islands would also be annexed by Russia. Lenin would stay in Switzerland or go to France or Italy. Ireland might be fully united but maybe not. German expansion in the colonies would be limited. Anatolia might be split into influential zones, Greece and Russia. Russia could take the name of second most powerful army. Poland would be given some autonomy in Vistula Land. France and Italy depending on their ideologies could support the Spanish republicans. Islamofascism could form in Turkey. Japan could become more angry and extremely nationalistic beyond our TL.
Italy would be unstable with four factions struggling for power, republicans/democrats, fascists, monarchists and communists. Monarchism or Communism would come on top with local support. (France and Austria-Hungary.) Greece wants more land and so a nationalistic regime could form. (Like Italy in OTL) Tensions could rise between Holy Alliance members. This is just what I think could happen if Russia won the Crimean Wars. Tell me if you like it and your thoughts, also is any of this possible? I didn't go into great detail like in Asia or the Balkans, me.
