Some other ideas i have for this timeline is the alternative World War Two - France turns into a fascist state in 1921 following the assassination of President Georges Sorel, and the fourth republic of France is declared. In the following year in Italy Mussolini comes to power but ITL he pushes for the abdication of Victor Emmanuel III and gets it, the King and his family fleeing to Switzerland. In 1930 the two countries form an alliance, the foundations have been laid for the Fascist Bloc.
In 1932 the dissolution of the Austro-Hungarian Empire is complete with the Republic of Austria holding its first elections in 1933 where Adolf Hitler wins and becomes the first President of Austria. He soon gets loans from France and Italy and quickly builds up Austrian industry and the armed forces, joining as an ally of Italy and France in 1935.
In 1937 a joint French-Italian-Austrian task force aids to Franco and puts him in power and France annexes Catalonia for the trouble. The four nations now form the Fascist Bloc. In 1938 the Milan Summit is held were the Soviet Union and Argentina also attend, here the Fascist Bloc allies itself with the Soviet Union and Argentina associates itself with the Bloc.
The leaders of the Bloc say they have formed this alliance in retaliation for the Triple Alliance of Germany, Great Britain and the United States.
In 1939, a surprise move Japan allies itself with the Fascist Bloc cosying up to the powers, though they will not fight together throughout the entire war they remain allies (like OTL Germany and Japan).
The war begins in 1940 with the Soviet invasion of the Kingdom of Poland with Germany honoring the Danzig Treaty signed in 1932 and declaring war on the Soviet Union mobilizing. This is followed by Great Britain who also mobilizes and then the Fascist Bloc declare war on the Triple Alliance, leading the United States to declare war in 1940.
Europe is entrenched in warfare for the next six years and it changes the world forever. The war ends in Europe in 1946 with the German nuclear attack on Moscow leading to the Soviet surrender. The war sees Fascism leave Europe and the regimes replaced with monarchies or democratic governments for example the Bourbons in Spain and France and the Savoy's briefly in Italy before a referendum is held and the monarchy abolished. The biggest U-turn in regimes was the restoration of the Romanovs to Russia in 1947 with the head of the family Grand Duke Andrei (son of Grand Duchess Xenia) taking the throne as Tsar Andrei I.
Following the war the Saint Petersburg Trails are held (OTL Numenberg trails) were the full atrocities of the war are revealed to the world via the press. One notable person persecuted by the trails are former Soviet leader Stalin sentenced to death, and one person who escaped trail and imprisonment and certain death was Adolf Hitler who secretly escaped to Argentina, it was revealed he fled there following the allied attack on Vienna, he died in 1954.
The the final months of the war the Americans pulled out to return to the states and fight in the Pacific, the same can be said of the British but they made better use of their troops in India and Australia.
With the end of the war in 1946 in Europe the Congress of Nations was created to keep peace throughout the world with many nations joining the HQ of this organisation would be in Zurich with the North American HQ being in Vancouver. Also created was NADA (North Atlantic Defense Alliance) to keep Europe from falling into war again and to protect all of its members from attacks from other nations (OTL NATO), the organisations HQ is Munich.
The two biggest powers in Europe the German Empire and the British Empire both dramatically change in the following decade. Germany grants Independence to all of its colonies apart from the Congo which is fully incorporated into the country and the nation is reformed and becomes the United Greater German States.
While Great Britain grants its dominions independence following the war and in 1963 grants all of its colonies independence, the British Commonwealth is created keeping the nations together in a lose federation with the INDEPENDENT countries having the British monarch as Head of State and a joint currency of the pound sterling each country having its own for example Canadian Pound.
