Jean Jaures survives the assassination attempt and is elected Prime Minister of France in 1919, governing alongside the Radicals. In the 1924 elections, he manages to gain a majority coalition alongside the Communists under Frossard. He signs a joint interests agreement with President Friedrich Ebert and Chancellor Otto Weis, while Lenin secretly meets with Foreign Minister Frossard, signing agreements concerning cooperation in the future. Lenin is succeeded by Leon Trotsky, with the support of Sergey Kamenev, Nikolai Bukharin and Alexei Rykov, who marginalize and eventually forcibly exile Stalin and his allies.
Jaures retires, and, for a time, right wing governments retain control in France; However, in 1930, facing intense public pressure to return, he is elected President of France, and Leon Blum, Frossard, and Maurice Thorez form a government under him. Fascist movements begin to be suppressed, and Jaures is forced to resign when he refuses to arrest Philippe Petain for meeting with reactionaries and fascists. Jaures flees to America, and he is replaced by Jacques Doriot, who establishes a Council of Ministers, including Leon Blum, Maurice Thorez, Marcel Deat, and a handful of others, which assumes legislative authority and signs a defense and trade pact with the Soviet Union.
Ernst Thalmann eventually is elected President over Hitler, and he begins purging the Nazis, monarchists, and reactionaries, with the help of the Strasser brothers and Ernst Rohm. President Thalmann appoints himself Chancellor, and signs a military pact with Trotsky and Doriot. Mussolini signs an agreement with Spain, Portugal, Yugoslavia, Finland, Poland, Czechoslovakia, Austria, and Romania*, leading a Fascist alliance against the Trio of Communists. World War Two breaks out when Mussolini sends troops to Austria to aid Engelburt Dollfuss against German-backed Communist protestors.
