Part 1: The Munich Coup, and Plans for the Future (1923-1925)
In what was, for the rest of the world, a footnote, Adolf Hitler was arrested, tried and executed for high treason, owing to a failed coup in Munich on the 9th November in 1923[1]. His co-conspirators were imprisoned. With his death, the far right-wing elements in German politics were left without a rallying figure, and the Communist elements gained more support.
In 1924, due to the (forged) Zinoviev letter, the Labour Party lost the 1924 elections in Britain. Lenin also died in early 1924, and Leon Trotsky managed to get his rival for control, Joseph Stalin, 'eliminated' sometime in the middle of that year[2]. Later, in December, a communist coup attempted in Estonia succeeded with supplies of Soviet ammunition and weaponry, terrifying the western world about the 'red menace'.
In 1925, Benito Mussolini declared that he was taking dictatorial powers, as Trotsky began his first Five-Year Plan and several brutal collectivisations, as a beginning to his plan to invade Europe and bring Communism to it by force,in order to facilitate the world revolution which Trotsky saw as coming soon and inevitable. Meanwhile, French troops abandoned the Ruhr area of Germany in response to an effective campaign of passive resistance. The year ended with the Locarno treaties, which normalised relations with the Weimar Republic
