History of Germany
To a pre-POD history, see wikipedia:History of Germany
After the German loss in the war, Fascism still grows, but instead of the hatred of Communism, Hitler used his anger against Britain, France and other western nations. Hitler still enters into World War II, but without an Anti-Comintern Pact and the need of a Non-Aggression Treaty with the Soviet Union.
Hitler then would be able to take the British Isles and Africa. Japan sees no need of Pearl Harbor attacks and the US doesn't get into the war. Hitler's Lebensraum doesn't include Russia. Therefore, Germany didn't invade its neighbour and kept in peace with it.
After the German invasion of Africa and Great Britain in 1943, Germany became the world's superpower, comprising about 25 million sq km and about half of the world's population. After the war, the government began their "Nazi policies", such as mandatory atheism and persecution of Jews and other minorities (which led to a massive migration of Jews to the Jewish Autonomous Oblast, making it declare independence becoming the Republic of Judea).
Seven years after the war, corruption and the lack of civil rights have destroyed Germany from inside. A crisis was installed and people lost hope in the government. At the outset of 1952, an anti-government organization named Rotfrontkämpferbund or the Alliance of the Red-Front Fighters was created. This left-wing movement started to gain force incredibly fast, and, on 7 October 1952, the Revolutionaries took over Berlin, which became known as the "Sozirev", creating a new form of government.
Non-democratic democracy, non-dictatorial dictatorship
After the establishment of the new government, a new type of democracy was used. The germans hadn't forgotten the tragical result of the Weimar Republic and was not confidence about a full multi-party democracy. So, in the new created People's Chamber decided to create a new type of elections, the German Democracy. The German Democracy, like in OTL Soviet Democracy, worked under a one-party system, the KPD, but with elected representatives and even secret ballots.
This new type of democracy started to reconstruct an economy in ruins and restructure freedom of speech and other democratic values. The negotiations with other countries started in weeks after the coup. The Christmas of 1952 the Berlin Accords was signed to give England and Wales (at the time the queen was exiled in Canada) back to the UK and give sovereignty to Africa, creating the African Democratic Republic.
Present and Future
Today, the Great German Republic is one of the rarest examples of working socialism and proof that socialism alongside with Capitalism can work together for the best of the people.
