Here's a try:
The Ottaman Empire stays out of WWI. This lets the Allies do better, causing victory in 1916. However, Italy joins the Centrals, but loses just as bad. Later,the Ottamans take the leftover parts of Austria-Hungary. No Russian Revoultion, so, Russian Empire!
The Weimar goverment collapses earlier, and Germany splits into city-states and minor nations. Prussia is the only strong one left, and it shares many Nazi ideals, beside the anti-semitism. They are a monarchy.
Italy also splits apart after Mussolini takes over. Several states declare independence, eventually slitting all of Italy.
